## What you see
Each bubble is one aggressive order – a market order that took liquidity from the order book. It sits at the order's time and volume-weighted price; green bubbles are buys, red bubbles are sells. The radius grows with the square root of the size, so the area reflects the volume; the largest 1 % of the loaded orders reach **Max radius**. Bubbles large enough show the size in the base currency (for example ETH) inside.

## How orders are merged
An exchange reports one large market order as a burst of trades, one per price level it consumed. The indicator joins them again: consecutive trades on the same side count as one order as long as each follows the previous one within **Merge window (ms)** and the whole burst stays within **Merge price span (ticks)**. Raise these values to merge more, lower them to see smaller fills.

## Data
Live trades are added while the chart is open. Past trades for the visible range are loaded only if your account includes tick downloads and Settings → Chart Settings → Enable Tick Download is on (see [Account](https://chartrider.com/docs/account/)). If the visible range is longer than **Max minutes in view**, past trades are not loaded and the status bar says so – zoom in to load them.

## Reading it
Clusters of large bubbles show where aggressive buying or selling was concentrated, and at which price.
