Yes. It is free on any website, blog or forum, with no account and no API key. Please keep the Swiftedge link in the widget and the line under it.

The last few minutes of the Binance BTCUSDT perpetual futures order book as a heatmap (green bids below price, violet asks above), every trade as a bubble sized by volume, the live price, and the options call wall, gamma flip and put wall from Deribit, OKX and Bybit. The options levels are estimates of dealer positioning, not measurements.

Will it slow my page down?

The snippet loads lazily, so the widget only starts when a visitor scrolls to it. While it is on screen it uses one live connection of about 2 KB per second.

Does it set cookies or track my visitors?

No cookies and no advertising trackers. A view is counted the same anonymous way as on swiftedge.uk, with a code that changes every day and no stored IP address. The privacy policy has the details.

Can I change the size?

Yes. Width follows your layout (100 %), and you choose the height and how many minutes are on screen above. It works from about 300 pixels wide.

Is it financial advice?

No. The widget shows market data and descriptive options levels for information and education. It is not a signal or a forecast.
