Open DepthMethod. Price, volume and order book from Binance USDⓈ-M BTCUSDT. Option levels use open interest from Deribit, OKX and Bybit with the common assumption that dealers are long calls and short puts; it is an estimate, not measured positioning. A wall is "held" when trades hit it and price turned, "pulled" when it vanished within seconds with almost nothing traded, "eaten" when most of it was traded away. Times are UTC.
