The Bitcoin order book shows all active limit buy and sell orders across 10 major exchanges — Binance, Coinbase, Kraken, Bybit, OKX and more — aggregated into a single combined view. Bids (green bars) represent demand at each price level; asks (red bars) represent available supply. Bar width reflects order volume. The bid/ask delta shows real-time imbalance across the entire market.
Fragmented liquidity is a major issue for Bitcoin traders: large whale walls on Binance might be invisible on Coinbase. TapeSurf's combined BTC order book removes this blind spot — showing you the true market depth, real support and resistance levels backed by actual order volume, and large orders as they appear, move, or get absorbed across all exchanges simultaneously.
