A live depth-of-market heatmap that runs beside your chart. Watch where size is resting, where it pulls just before price arrives and where the market gets absorbed.
Full order-book history painted as a heatmap, not just the top of book
Brighter means bigger — spot walls and icebergs at a glance
Absolute size thresholds so a level that matters always gets colour
Same symbol and timeframe as your chart, side by side in one window
