A heat map is an easy way of displaying trading activity in the DOM over time. Use it for scalping and finding entry points. An enhanced heat map provides more useful opportunities for ATAS platform users when working with Scalping DOM and DOM Levels indicators.
What is a heat map and why do you need it?
A heat map is a way to display activity in the DOM over time. The brighter the color of a price level on the chart, the larger the volume of limit orders placed at that level in the DOM.

The above screenshot demonstrates the Scalping DOM indicator with the heat map in action (1).
- dark blue cool colours correspond to low volumes in the DOM;
- yellow and orange shades indicate high volumes that are likely to reveal the interest of an important market participant.
Analyzing the heat map, you can notice the activity of a limit buyer (2). Apparently, this is a major player’s robot buying up assets at a breakout of the local resistance level (3).
This is just one of many examples showing how a heat map can be an easy and useful instrument for tracking the actions of big players in order to uncover their intentions and get some ideas about directions that the price will move.
Use the heat map in ATAS indicators for:
- scalping;
- finding more accurate entry points – minimize the risk;
- learning – study the markets safely in the Market Replay mode, use the heat map to track the behaviour patterns of big players in the DOM.
Advantages of the ATAS heat map
- Accuracy. Its readings are based on tick data coming from exchanges (and stored on ATAS servers).
- Flexibility. In the settings, you can specify in detail the parameters of the colour scheme, contrast, and others.
- Optimization. Launching the heat map does not heavily load system resources. The playback and centring occur smoothly.
- Built-in navigation. If necessary, you can move the map up/down, left/right with your mouse, as well as quickly return to the right edge.
- Beauty. No comments are needed ;)
