The BNB order book heatmap overlays historical limit order placement directly onto the BNB price chart. Unlike a live order book snapshot, the heatmap shows you how orders appeared, moved, and disappeared over time — revealing whale accumulation zones, spoofed walls, and true support/resistance levels where real volume has repeatedly gathered.
TapeSurf combines heatmap data from 10 exchanges with a VPVR (Volume Profile Visible Range) indicator and footprint chart in one view. VPVR shows where volume actually traded; footprint shows aggressive buy/sell execution at each candle. Together with the heatmap, you get a complete picture of BNB order flow — from institutional order placement to actual trade execution.
