# Swiftedge: complete reference > Swiftedge (also written SwiftEdge) is Swiftedge ApS, a Danish company that builds free live Bitcoin order flow tools for futures and options. Swiftedge Depth (https://swiftedge.uk/depth) shows the live BTCUSDT perpetual futures order book from Binance as a heatmap in the browser, with every trade as a bubble sized by volume. Swiftedge Options (https://swiftedge.uk/options) shows the live BTC options chain from Deribit, OKX and Bybit. Both are free and need no sign-up. Descriptive only: options-implied odds are not a forecast, dealer positioning is estimated, and nothing on the site is financial advice.

Not affiliated with Binance, TradingView, Deribit, OKX, Bybit, or other businesses using a similar name such as brokers called "Swift Edge". ## Swiftedge Depth: what is on the screen - Heatmap: resting limit orders by price (vertical) and time (horizontal). Green bands below price are bids, violet bands above price are asks. Brighter means more resting size. Colour is relative (log scale by default), so check the size readout before calling a level large. - Price line: the mid price, drawn in white. - Bubbles: every executed trade at its price and time, sized by volume. Teal = the buyer crossed the spread (aggressive buy); violet = the seller crossed it (aggressive sell). - Executions: optional markers that highlight large trades across the chart. - Volume pane: traded volume per time bucket under the chart, with CVD (cumulative volume delta: aggressive buying minus aggressive selling since 00:00 UTC) drawn over it; the CVD button in the pane's corner switches it on and off. - Depth profile: the current order book binned to the visible price scale, beside the price axis. - Side panel cards: Mentor, Session Orbs, GEX, 5-minute flow (aggressive volume in the running five-minute window), Buy vs sell (share of volume that lifted the ask per timeframe) and News. ## Indicators in Depth Added from "+ add indicator" (top left of the chart) or the "indicators" button in the header. New visitors start with Liquidity, Bubbles and VWAP. - Liquidity: the order book heatmap, with settings for log scale, contrast (gamma), visibility, floor, deep-book brightness and smoothing. - Bubbles: every trade as a bubble; minimum size, aggregation window and bubble scale can be adjusted. - Executions: markers for large trades, with a minimum size and length setting. - VWAP: volume-weighted average price for the current day, drawn as a yellow line. - Mentor: a descriptive, step-by-step market read covering structure, liquidity, volume profile, order flow, timeframes and positioning, with scenarios and the level that would invalidate each. Calculated once for all visitors with fixed default settings. Not a proven signal. - Session Orbs: opening ranges for the Tokyo, London and New York sessions. RVR = opening-range volume against the same session's average. IVB = opening range plus or minus k times the VWAP deviation before the open, with k following implied volatility. Targets show historical hit rates for the same session over 60 days; these are descriptive. - GEX (gamma exposure, options): see the next section. ## GEX and options levels - Source: BTC options on Deribit, OKX and Bybit, one snapshot per minute. Faint columns before the dashed marker on the chart are reconstructed from today's open interest with DVOL-scaled implied volatility, not measured. - Formula: GEX = gamma x open interest x price^2 x 1 %, in USD. - Sign: GEX levels (gamma flip, call and put walls) and the GEX heatmap use the common assumption that dealers are long calls and short puts. By default, the dealer hedge map, the regime card and the dealer positions instead use dealer positions estimated from Deribit trade flow (taker = customer, maker = dealer, clipped to open interest); they cover Deribit only, because OKX and Bybit have no free trade history. If the flow sign is also switched on for the GEX levels, OKX and Bybit stay on the assumption there. Both settings can be changed in the GEX settings. All are estimates, not measured positioning. - 0DTE = options expiring within 24 hours (drawn cyan for positive, magenta for negative); carry = later expiries (amber positive, violet negative). Deribit's daily BTC options expire at 08:00 UTC. - Gamma flip = the price where total GEX changes sign. CW / PW = call wall / put wall, the strikes with the largest call / put gamma. - Dealer hedge estimate: how many BTC dealers would buy or sell on a 1 % move down or up, under the sign model in use. Long gamma tends to dampen moves; short gamma can amplify them. - All GEX outputs are estimates, not measured dealer positioning, and not financial advice. ## Swiftedge Options: the live BTC options chain URL: https://swiftedge.uk/options . Free, no account. Guide: https://swiftedge.uk/guide/options-chain - Rows are strikes, high strikes on top, centred on the live BTC price. Calls grow to the left, puts to the right. - Row height = the options-implied (risk-neutral) odds that BTC settles near that strike at the selected expiry, read from the implied volatility smile. Rows have a minimum height so the wings stay readable. It describes what options cost; it is NOT a forecast. Thin brackets at the edges mark the +/-1 sigma expected move (about price x ATM IV x sqrt(days/365)). - Bar length = open interest in BTC (Deribit, OKX and Bybit added up). Bar colour = who was aggressive at that strike today, read from the taker side: teal = buyers dominated, violet = sellers dominated, muted neutral = roughly balanced. A thin white line inside the bar = today's traded volume (×N when volume exceeds open interest). - Row glow = estimated dealer gamma: blue where hedging leans against moves, pink where it leans with them. Amber dashed line = gamma flip. Tags mark the call wall, put wall, gamma flip and max pain for the selected expiry. - Futures spine in the middle = a mini Swiftedge Depth for the Binance BTCUSDT perpetual: price trail, the biggest futures walls as glowing streaks, futures trades as bubbles, always ending at now. It has its own price zoom; LINK keeps the live price at the same height on the spine as on the chain, so the white price line runs straight across. - Live option trades fly in from the edges and merge into their strike (teal bought, violet sold, white ring = block trade). The bottom strip sums the last hour of options money flow: bullish premium (calls bought + puts sold) versus bearish premium (puts bought + calls sold), direction from the taker. Premium is not exposure. - Expiry tabs: daily, weekly, monthly and quarterly expiries, plus All expiries. BTC options on Deribit, OKX and Bybit settle at 08:00 UTC. A one-line summary above the chain names the options centre, the biggest bets, which side dominated today and the nearest futures walls. - Optional indicator "Dealer desk (est.)": an estimated hedge column by price and a card with the dealer regime, the hedge on a 1 % move, the futures hedge, time decay and the 0DTE share. Two models: standard (dealers long calls, short puts) or trade-flow (Deribit positions rebuilt from who took each side; other venues by assumption). - Caveats: Row height shows the options-implied (risk-neutral) odds that BTC settles near each strike at the selected expiry, read from today's option prices and the implied volatility smile. It describes what options cost; it is not a forecast. Dealer positions are not public, so dealer gamma, the call wall, the put wall and the gamma flip are estimated, by default under the standard assumption that dealers are long calls and short puts on Deribit, OKX and Bybit. Buy/sell direction is read from the taker side. Futures walls are resting orders and can be pulled at any time. Descriptive only, not advice or a prediction. ## Controls - Mouse: wheel = zoom time; shift + wheel = zoom price; drag = pan; double-click = back to live with auto-scroll and auto-scale; Esc = back to the cursor tool. - Header: "today" shows the whole day; AUTO-SCROLL keeps the right edge at now; AUTO-SCALE refits the price axis. - Alerts (button in the header): price alerts (type a price or pick it on the chart; shown as a dashed line) and a large-wall alert (at least N BTC on one $10 price level within a chosen distance of price, held for two checks, at most every 15 minutes per level). Sound and optional browser notifications; they run while the tab is open and are saved only in the browser. Swiftedge Options has the same price alerts plus alerts for BTC near the call wall or put wall, crossing the gamma flip, and a wall moving to another strike. - App: Swiftedge can be installed from the browser (Chrome/Edge on desktop and Android; on iPhone via Share, Add to Home Screen) and then opens in its own window. - Touch: drag to scroll, pinch horizontally to zoom time and vertically to zoom price, double-tap to return to live, press and hold to inspect a bubble or price level, draw with a finger. On a phone a bottom bar holds Indicators, Draw (the drawing toolbar), Alerts, Share, Chat and More (panel, whole day, auto-scale, about); the live price is at the top. On tablets the side panel is a drawer that opens from the bottom. - Share: the Share button (Depth and Options) turns a moment into an image card drawn by Swiftedge from its own data, with a link to a page that opens that moment. In Depth it uses the spot under the pointer, otherwise now; in Options the strike and expiry. Share links for X, Facebook, Reddit, Telegram, WhatsApp and LinkedIn; for Instagram and TikTok the phone's share sheet or a 4:5 image download. Cards are kept for 180 days. - Chat: one live room shared by Depth and Options, no account (a nickname), cleared every day at 00:00 UTC. New visitors read for 30 seconds before writing; links only to swiftedge.uk, TradingView and YouTube, after 30 minutes. Not financial advice. - What's new: https://swiftedge.uk/updates lists platform updates; returning visitors see a short card with what changed since their last visit. - Drawing: 24 tools in five groups (lines, Fibonacci, shapes, text and labels, positions and measuring), including trend line, horizontal line and ray, parallel channel, Fibonacci retracement and extension, rectangle, text, price label, long and short position, price and date ranges. Shortcuts: Alt+T trend, Alt+H horizontal, Alt+F fib, Alt+Shift+R rectangle; Delete deletes; Ctrl+Z / Ctrl+Y undo / redo. Drawings are saved in the browser's local storage. ## How to read an order book heatmap 1. Find the bright bands: green below price are bids, violet above are asks. The brightest are liquidity walls. 2. Check distance and age: how far from price, and how long the band has been there. 3. Watch contact: a wall HOLDS (bubbles stack on it, it stays bright, price turns), is EATEN (it dims as trades land and price moves through) or is PULLED (it vanishes before trades land on it). 4. Read the bubbles: size = volume, colour = aggressor. 5. Mind the time of day: liquidity is thinner between sessions and deeper around the London and New York opens. 6. Add context: VWAP, session opening ranges and options levels (gamma flip, call wall, put wall). Displayed size is a claim; traded size is evidence. Orders can be cancelled instantly (spoofing is placing orders without intent to fill), and hidden size such as icebergs only appears when it trades. ## Daily BTC report - URL: https://swiftedge.uk/btc/today (today, updated hourly). Each finished UTC day keeps its own page at /btc/, for example https://swiftedge.uk/btc/2026-10-14. All days are listed, newest first, at https://swiftedge.uk/btc. - Contents: close or last price, range and volume; the Asia, London and New York sessions (change, range, high/low times, volume, wall events); a heatmap chart of the day with options walls and wall events; liquidity wall events classified as held, pulled or eaten from the trades at the wall's own price; options positioning (call wall, put wall, gamma flip, 0DTE walls, dealer gamma regime) from Deribit, OKX and Bybit open interest; the largest resting walls within 2.5 % of price; the next options expiries. - Definitions used: held = trades hit the wall and price turned; pulled = the wall vanished within seconds with almost nothing traded; eaten = most of it was traded away. Times are UTC. Descriptive only. ## Data sources and processing - Order book: Binance USD(S)-M futures BTCUSDT depth stream (100 ms), grouped into a column every 0.25 s. - Trades: every BTCUSDT trade from Binance USD(S)-M futures, with the aggressor side as marked by Binance. - Options: Deribit, OKX and Bybit BTC options, one snapshot per minute. - Processing happens on Swiftedge's servers; the browser connects only to swiftedge.uk. - The book is grouped into price bins; the deep band (about 0.22 % to 2 % from price) is coarser; after a server restart the deep book refills over time; history is downsampled when zoomed out. ## Limitations - Bitcoin only (BTCUSDT perpetual), and one exchange's order book: not the whole market. - Prices are binned, so exact sizes can differ slightly from the exchange. Check prices on your exchange before trading. - GEX sign and dealer hedging are estimates (the common assumption, or a sign estimated from Deribit trade flow), not measured positioning. - Swiftedge Options: row height is options-implied (risk-neutral) odds, not a forecast; call wall, put wall, gamma flip and the Dealer desk are estimates; max pain is arithmetic on open interest, not a target. - Mentor, Session Orbs hit rates and the daily report are descriptive. They are not forecasts or signals. - Public beta: features can change, and the service can be unavailable without notice. ## Privacy No account. No tracking cookies, no advertising trackers, and IP addresses are not stored in visitor statistics (visits are counted with an anonymous code that changes daily and cannot follow anyone between days). Per page view the statistics keep the page, the daily code, country, device type, browser and OS family, the linking website and any utm_source tag. Depth and Options also count app time and, anonymously, which features are used (a feature name from a fixed list, never what is drawn or typed). Detailed records are deleted after 90 days. Drawings and settings stay in the browser's local storage. ## FAQ Q: What is Swiftedge? A: Swiftedge is a Danish company, Swiftedge ApS, that builds free order flow tools for Bitcoin traders: Swiftedge Depth, a live futures order book heatmap, and Swiftedge Options, a live BTC options chain, both in the browser. Swiftedge also publishes a daily BTC market structure report and the SwiftEdge indicators on TradingView. Q: What is Swiftedge Depth? A: Swiftedge Depth is a free, browser-based order flow tool for Bitcoin. It shows the live BTCUSDT perpetual futures order book as a heatmap and draws every trade as a bubble sized by volume. You can add VWAP, the Mentor analysis, Session Orbs, options gamma exposure (GEX), CVD and 24 drawing tools, set price and wall alerts, and share any moment as an image. The chart updates four times a second. Q: Is Swiftedge Depth free? A: Yes. Depth is free during the public beta and needs no account and no download. A paid Premium plan with extra features is planned for later; a free version will remain available. Q: Is Swiftedge the same as SwiftEdge on TradingView? A: Yes. The SwiftEdge profile on TradingView is run by the same team and links to swiftedge.uk. As of October 2026 it has 41 published scripts covering order flow, liquidity, ICT and smart money concepts, VWAP and trading sessions. Q: Is Swiftedge a broker or a signal service? A: No. Swiftedge does not take deposits, execute trades, manage money or sell trading signals. It shows market data and descriptive analysis. Swiftedge is not affiliated with other businesses that use a similar name, such as brokers or trading platforms called "Swift Edge". Q: Which market does Depth show? A: Bitcoin perpetual futures, BTCUSDT, from Binance USDⓈ-M futures: the order book out to about 2 % from price and every executed trade. Options data for the GEX indicator comes from Deribit, OKX and Bybit. Other coins and exchanges are not available yet. Q: How often does the chart update? A: Depth adds a new column of order book data four times a second, one every 0.25 seconds, and draws trades as they print. With auto-scroll on, the chart moves continuously with the live data. Q: How far back can I scroll? A: At least the last 24 hours; older hours load as you scroll back. Drag the chart to the left, or press today in the header (on a phone: More, then Whole day) to see the whole day, then zoom in anywhere down to the raw order book. History is downsampled when you zoom out and loads in full detail when you zoom back in. Q: Does it work on a phone? A: Yes. On a phone, Depth has a bar at the bottom for indicators, drawing tools, alerts, sharing, chat and more, and the live price sits at the top. Drag to scroll, pinch to zoom time or price, double-tap to return to live, and press and hold the chart to inspect a bubble or a price level. On tablets the side panel opens as a drawer from the bottom. Q: How do I add indicators? A: Click + add indicator at the top left of the chart, or the indicators button in the header (on a phone: Indicators in the bottom bar). The catalogue has Liquidity (the heatmap), Bubbles, Executions, VWAP, Mentor, Session Orbs and GEX. New visitors start with liquidity, bubbles and VWAP. CVD (cumulative volume delta since 00:00 UTC) is switched on and off with the CVD button in the corner of the volume pane; the CVD guide explains what it shows. Q: Are my drawings and settings saved? A: Yes, in your own browser's local storage, so they are there next time on the same device. They are not sent to Swiftedge, and clearing the site data in your browser removes them. Q: Can I set alerts? A: Yes. Click Alerts in Depth or Options. In both you can set price alerts, and pick the price straight on the chart. Depth can also alert you when a large wall appears near price; Options when BTC comes near the call wall or put wall, crosses the gamma flip, or a wall moves to another strike. Alerts sound and can show a browser notification. They run while the tab is open, also in the background, and are saved only in your browser. Q: Can I share what I see on the chart? A: Yes. Click Share in Depth or Options (on a phone, in the bar at the bottom). In Depth, point at a spot on the chart first to share that moment, otherwise it shares now; in Options, point at a strike. Swiftedge draws an image card from its own data with a link back to that moment, ready for X, Facebook, Reddit, Telegram, WhatsApp and LinkedIn. For Instagram and TikTok, a phone opens its own share sheet with the image, and a computer downloads a 4:5 image to post. Q: Is there a chat? A: Yes. Depth and Options share one live chat room, with no account: pick a nickname and write. The room is cleared every day at 00:00 UTC. New visitors can read for 30 seconds before writing, and links (only to swiftedge.uk, TradingView and YouTube) unlock after 30 minutes. Nothing in the chat is financial advice; the chat rules cover moderation and appeals. Q: Where can I see what is new? A: On the What's new page, newest first. When you come back to Depth or Options after an update, a short card lists what changed since your last visit. Q: Can I install Swiftedge as an app? A: Yes. In Chrome or Edge on a computer or Android phone, use Install app on the home page, Depth or Options, or Install in the browser menu; Swiftedge then opens in its own window. On an iPhone, open swiftedge.uk in Safari, tap Share and then Add to Home Screen. It is the same site, so it needs no updates. Q: What do the colours mean? A: In the heatmap, green bands below price are resting buy orders (bids) and violet bands above price are resting sell orders (asks); brighter means more size at that price. Bubbles are executed trades: teal when a buyer crossed the spread, violet when a seller did, sized by volume. Q: What is a liquidity wall, and can it be fake? A: A liquidity wall is an unusually large resting order at one price. Some walls trade when price arrives; others are cancelled before price gets there, which is called spoofing when it is done to mislead. Trades at the level are evidence, displayed size alone is not; the liquidity walls guide covers how to tell them apart. Q: What is the difference between an order book heatmap and a depth chart? A: A depth chart or DOM ladder shows the order book at one moment. A heatmap shows the same book over time, so you can see how long a level has been there, whether it grew or shrank, and what price did when it arrived. Depth shows both: the heatmap and a depth profile of the current book beside the price axis. Q: Is an order book heatmap the same as a liquidation heatmap? A: No. An order book heatmap shows real resting limit orders on an exchange. A liquidation heatmap is a model that estimates where leveraged positions might be forced to close. Swiftedge Depth shows the order book, not liquidation estimates. Q: What is Swiftedge Options? A: Swiftedge Options is a free live Bitcoin options chain for BTC options on Deribit, OKX and Bybit, in the browser with no account. Strikes are rows, calls on the left and puts on the right. Bars show open interest, coloured by which side was aggressive today, live option trades fly in, estimated dealer levels mark the call wall, put wall, gamma flip and max pain, and a futures spine in the middle shows a mini Swiftedge Depth of the BTCUSDT perpetual. Q: How do I read the options chain? A: Each row is a strike, high strikes on top, centred on the live BTC price. Call open interest grows to the left and put open interest to the right, so the biggest bars are where most contracts are open. Pick an expiry in the tabs at the top, or All expiries. The options chain guide walks through it with annotated screenshots. Q: What does row height mean in Swiftedge Options? A: Row height shows the options-implied (risk-neutral) odds that BTC settles near each strike at the selected expiry, read from today's option prices and the implied volatility smile. It describes what options cost; it is not a forecast. Thin brackets at the edges mark the ±1σ expected move, the range that holds about two in three of the outcomes options price. Q: What do the bar colours and the white line mean? A: Bar length is open interest in BTC on Deribit, OKX and Bybit. The colour shows who was aggressive at that strike today, read from the taker side of each trade: teal when buyers dominated, violet when sellers did, a muted neutral when it was roughly balanced (the colour strengthens from about 55 % one way). The thin white line inside the bar is today's traded volume relative to open interest; a label such as ×2.8 means more traded today than is open. Q: Are the call wall, put wall, gamma flip and max pain real dealer positions? A: The call wall, put wall and gamma flip are estimates. Dealer positions are not public, so dealer gamma, the call wall, the put wall and the gamma flip are estimated, by default under the standard assumption that dealers are long calls and short puts on Deribit, OKX and Bybit. Max pain is plain arithmetic on open interest: the settlement price at which option holders together would collect the least. None of them is a target or a forecast. Q: What is the futures spine in the middle of the chain? A: A mini Swiftedge Depth for the Binance BTCUSDT perpetual: the price trail, the biggest futures walls as glowing streaks and futures trades as bubbles, always ending at now. It has its own price zoom; LINK keeps the live price at the same height on the spine as on the chain, so one white line runs straight across. Q: What is the Dealer desk indicator? A: An optional indicator, labelled Dealer desk (est.), that adds an estimated hedge column by price and a card with the dealer regime, the hedge on a 1 % move, the futures hedge, time decay and the 0DTE share. It can use the standard assumption or Deribit positions rebuilt from trade flow. Both are estimates; where they disagree, treat the picture as uncertain. Q: Is Swiftedge Options free? A: Yes. Swiftedge Options is free and needs no account and no download. It shows market data and descriptive analysis, not advice. Q: What does the GEX indicator show? A: GEX estimates options gamma exposure from BTC options on Deribit, OKX and Bybit, updated once a minute. Depth draws the gamma flip, the call wall and the put wall on the chart, separates 0DTE options (expiry within 24 hours) from later expiries, and estimates how much dealers would hedge on a 1 % move; each term is defined in the Swiftedge glossary. Q: Why is the GEX sign an estimate? A: Open interest shows how many options exist, not who holds them, so the sign of dealer gamma has to be estimated. GEX levels (gamma flip, call and put walls) and the GEX heatmap use the common assumption that dealers are long calls and short puts. By default, the dealer hedge map, the regime card and the dealer positions instead use dealer positions estimated from Deribit trade flow (taker = customer, maker = dealer, clipped to open interest); they cover Deribit only, because OKX and Bybit have no free trade history. If the flow sign is also switched on for the GEX levels, OKX and Bybit stay on the assumption there. Both settings can be changed in the GEX settings. All are estimates, not measured positioning. Q: What is the daily BTC report? A: A page written from the data every day at swiftedge.uk/btc/today. It covers the Asia, London and New York sessions, liquidity walls that held, were pulled or were eaten, options levels such as the call wall, put wall and gamma flip, the largest resting walls and the next options expiries. Today's page updates hourly, and each finished day keeps its own dated page, listed in the daily report archive. Every Sunday a weekly report sums up the week, Bitcoin levels today shows the current walls and options levels on one page, and new reports are in the RSS feed. Q: Where does the data come from? A: Order book and trades come from Binance USDⓈ-M futures (BTCUSDT). Options data for Swiftedge Options and the GEX levels comes from Deribit, OKX and Bybit. Swiftedge's servers collect and process the data, so your browser connects only to swiftedge.uk, not to the exchanges. Q: How accurate is the order book in Depth? A: Close to the exchange, but not identical. The book is grouped into price bins, the deep part from about 0.22 % to 2 % from price is shown at a coarser resolution, and after a server restart the deep book takes a while to fill in again. Always check prices on your exchange before you place an order. Q: Does Swiftedge track me? A: Swiftedge sets no tracking cookies, uses no advertising trackers and does not store IP addresses in its visitor statistics. Visits are counted with an anonymous daily code that cannot follow you from one day to the next. Depth and Options also count anonymously which features are used, such as an indicator or a drawing tool being switched on: only the feature's name from a fixed list, never what you draw or type. The details are in the privacy policy. Q: Is Swiftedge financial advice? A: No. Everything on swiftedge.uk is for information and education. Analyses, levels and historical hit rates are descriptive, not signals or forecasts, and trading involves substantial risk of loss. Q: Is there a free alternative to Bookmap for Bitcoin? A: Swiftedge Depth is a free Bookmap-style order book heatmap for Bitcoin that runs in the browser with no account and no download. It covers BTCUSDT perpetual futures on Binance only; platforms such as Bookmap cover many more markets and exchanges. The Bookmap alternative page lists what Depth does and does not do. ## Glossary - Order book: The list of all resting buy and sell limit orders for a market, sorted by price. Bids sit below the current price and asks above it, and the book changes many times a second. (https://swiftedge.uk/glossary#order-book) - Limit and market orders: A limit order buys or sells at a set price or better and, if it cannot fill at once, rests in the book; these waiting orders are what a heatmap draws. A market order trades immediately against them. (https://swiftedge.uk/glossary#limit-order) - Bid, ask and spread: The bid is the highest price a buyer will pay right now; the ask is the lowest price a seller will accept. The gap between them is the spread, which a taker pays and a maker earns. (https://swiftedge.uk/glossary#bid-ask) - Market depth (DOM): How much size rests at each price near the current price. A DOM ladder or depth chart shows one moment; a heatmap shows it over time. Depth shows both, with a depth profile beside the price axis. (https://swiftedge.uk/glossary#market-depth) - Order book heatmap: A chart that colours each price level by its resting liquidity, with time on the horizontal axis. Bright bands are large resting orders and dark areas are thin liquidity. (https://swiftedge.uk/glossary#order-book-heatmap) - Liquidity wall: An unusually large resting order, or cluster of orders, at one price, seen as a bright band on a heatmap. When price arrives, a wall can hold, be eaten by aggressive orders, or be pulled. (https://swiftedge.uk/glossary#liquidity-wall) - Absorption: Aggressive orders keep trading into a level, but the resting size keeps being replenished, so price does not get through. On a heatmap, bubbles stack on a band that stays bright. (https://swiftedge.uk/glossary#absorption) - Pulled liquidity: Resting size that disappears without trading, often as price approaches. The band vanishes with no bubbles on it, which is very different from a wall that was eaten. (https://swiftedge.uk/glossary#pulled-liquidity) - Spoofing: Placing large orders with no intention of letting them fill, to create a false picture of supply or demand. It is prohibited on regulated markets, but not every pulled order is spoofing. (https://swiftedge.uk/glossary#spoofing) - Iceberg order: A large order that shows only part of its size and refills as that part trades. The tell is a level that trades far more volume than it ever displays. (https://swiftedge.uk/glossary#iceberg-order) - Sweep: An aggressive order that trades through several price levels at once, taking the resting liquidity in between. On a heatmap it shows as a burst of bubbles and a jump in price. (https://swiftedge.uk/glossary#sweep) - Maker and taker: A maker places a limit order that rests in the book; a taker trades at once against it. Makers add liquidity and usually pay lower fees; takers remove it and pay for immediacy. (https://swiftedge.uk/glossary#maker-taker) - Aggressor side: The side of a trade that crossed the spread. Binance marks it on every trade, and Depth colours its bubbles by it: teal when a buyer lifted the ask, violet when a seller hit the bid. (https://swiftedge.uk/glossary#aggressor) - Delta: Aggressive buy volume minus aggressive sell volume over a period, such as one bar. It measures urgency, not who was right. (https://swiftedge.uk/glossary#delta) - Cumulative volume delta (CVD): The running total of delta. On its own it can mislead: heavy buying into a seller who keeps refilling lifts CVD while price goes nowhere. Depth draws CVD since 00:00 UTC over its volume pane. (https://swiftedge.uk/glossary#cvd) - VWAP: Volume-weighted average price: the average price of all trades over a period, weighted by size. Depth draws the current day's VWAP as a yellow line. (https://swiftedge.uk/glossary#vwap) - Volume profile: A histogram of traded volume by price over a period: where the market did its business rather than where orders rested. It is one of the steps in Depth's Mentor analysis. (https://swiftedge.uk/glossary#volume-profile) - Point of control (POC): The price with the most traded volume in a volume profile, the level the market accepted most in that period. (https://swiftedge.uk/glossary#poc) - Value area: The range around the point of control that holds a set share of the period's volume, commonly 70 %. Its edges are the value area high (VAH) and low (VAL). (https://swiftedge.uk/glossary#value-area) - Trading sessions: Bitcoin trades around the clock, but activity follows the business day in Asia, Europe and the US. Depth and the daily report use Asia (Tokyo), London and New York sessions in local opening hours. (https://swiftedge.uk/glossary#trading-sessions) - Opening range: The high and low of the first minutes of a session. Session Orbs in Depth draws it for Tokyo, London and New York with relative volume and historical target hit rates from the past 60 days. (https://swiftedge.uk/glossary#opening-range) - Perpetual futures: Futures with no expiry date, held close to the spot price by a funding rate. BTCUSDT on Binance USDⓈ-M futures, the market Depth shows, is a perpetual settled in USDT. (https://swiftedge.uk/glossary#perpetual-futures) - Funding rate: A periodic payment between longs and shorts on a perpetual future: longs pay when it trades above spot, shorts when below. On Binance's BTCUSDT perpetual it is normally paid every eight hours. (https://swiftedge.uk/glossary#funding-rate) - Liquidation: The forced closing of a leveraged position whose margin no longer covers the loss. Liquidations execute as market orders, so a cluster of them can sweep the book. (https://swiftedge.uk/glossary#liquidation) - Strike price: The price at which an option can be exercised. Swiftedge Options draws one row per strike, centred on the live BTC price, with calls on the left and puts on the right. (https://swiftedge.uk/glossary#strike) - Expiry: The time an option contract settles. BTC options on Deribit, OKX and Bybit settle at 08:00 UTC, with daily, weekly, monthly and quarterly expiries. Swiftedge Options has a tab for each expiry and an all-expiries view. (https://swiftedge.uk/glossary#expiry) - Open interest: The number of futures or options contracts still open. In Swiftedge Options, bar length is open interest in BTC at each strike on Deribit, OKX and Bybit: where positions sit, not which way they lean. It is also the main input to gamma exposure. (https://swiftedge.uk/glossary#open-interest) - Implied volatility (IV): The volatility priced into options. ATM IV is the implied volatility of strikes near the current price. Deribit publishes a Bitcoin implied volatility index, DVOL, and Session Orbs scales its breakout bands with implied volatility. (https://swiftedge.uk/glossary#implied-volatility) - Implied odds (risk-neutral probability): The chance of each settlement price that today's option prices imply, read from the implied volatility smile. It is a risk-neutral measure: it describes what options cost, not what will happen, so it is not a forecast. In Swiftedge Options it sets the height of each row. (https://swiftedge.uk/glossary#implied-odds) - Expected move: How far options price BTC to move by an expiry: about price × ATM IV × √(days/365). About two in three priced outcomes fall inside ±1σ. Options-implied, not a forecast. (https://swiftedge.uk/glossary#expected-move) - Max pain: For one expiry, the settlement price at which option holders together would collect the least, computed from open interest. It is arithmetic on open positions, not a target. (https://swiftedge.uk/glossary#max-pain) - Options premium flow: The money paid for options over a period, split by direction from the taker of each trade: calls bought and puts sold count as bullish premium, puts bought and calls sold as bearish premium. Premium is not exposure. (https://swiftedge.uk/glossary#options-premium-flow) - Gamma exposure (GEX): An estimate of how much options dealers must buy or sell to stay hedged as price moves. Depth computes gamma × open interest × price² × 1 %, in USD, from Deribit, OKX and Bybit. Who holds the options is not known: the GEX levels assume dealers are long calls and short puts, while the dealer hedge map defaults to dealer positions estimated from Deribit trade flow (Deribit only). (https://swiftedge.uk/glossary#gex) - Gamma flip: The price where estimated dealer gamma changes sign: on one side hedging tends to dampen moves, on the other it tends to add to them. Under the usual assumption dealers are long gamma above it and short gamma below it. An estimate. (https://swiftedge.uk/glossary#gamma-flip) - Call wall and put wall: The strikes with the largest estimated call gamma and the largest put gamma for an expiry, where dealer hedging tends to concentrate. They are often watched as ceiling-like and floor-like levels and often sit at round numbers. Depth marks them CW and PW; Swiftedge Options tags them on the chain. Estimates, not measured positions. (https://swiftedge.uk/glossary#call-wall-put-wall) - 0DTE options: Options that expire the same day; in Depth, within 24 hours. BTC options on Deribit, OKX and Bybit settle at 08:00 UTC. Their gamma sits close to price, so Depth colours them separately. (https://swiftedge.uk/glossary#zero-dte) - Long and short gamma: Long-gamma dealers hedge by selling rallies and buying dips, which tends to dampen moves. Short-gamma dealers buy rallies and sell dips, which can amplify them. Dealer positions are not public, so which regime applies is an estimate.
