Execution bubbles: seeing aggression on the heatmap

DeepDom's Volume Bubbles put the time & sales directly on the chart. Each bubble is an execution, or a group of executions, placed at the time and price where it happened. Its size is proportional to the volume, its color shows the side: an aggressive buy or an aggressive sell. Combined with the heatmap, they show the full face-off: the liquidity that is waiting, and the aggression that comes to test it.

Bubbles are often how a beginner “sees” order flow for the first time: you understand instantly who is hitting, where, and how hard.
