What I meant by “setting the interval between the UI and DOM snapshot short” is reducing both update intervals so the heatmap reacts to order book changes more frequently and with less latency.
In my setup, I set:
• UI Update Interval to 100ms
• DOM Snapshot Interval to 100ms
By keeping both intervals short, the heatmap reflects liquidity appearing and disappearing almost immediately, instead of updating in larger steps. This makes the transitions smoother and the behavior closer to Bookmap, where you can visually track subtle changes in resting liquidity and absorption in near real time.
If performance becomes an issue, reducing the displayed depth helps keep the system responsive.
