Heatmap

The indicator shows data changes in the DOM.

It has minimum and maximum volumes, the basic ask and bid colors, and the colors of asks and bids that exceed the maximum volumes.

If the volume of the limit level in the DOM is between the minimum and maximum, the price level color is proportional to the volume. If the volume of the limit level exceeds the maximum, the price level will be the maximum volume color.

This indicator is best used for tick charts with a value of 1, where every bar (tick) stands for a separately aggregated trade.

Indicator settings

Parameters

Name	Description
Depth of market	Changes the DOM
Expanded DOM	Extends levels from the current price to the price scale.
Color map	Visualization settings for volume in the indicator.
Lower cutoff %	Corresponds to the upper cutoff.
Lower cutoff V	Minimum volume. Levels with order volumes lower than the minimum value will not be displayed.
Upper cutoff %	Let’s say the maximum volume permitted in the visible range is 1000. We can also say there’s a level with volume 800. If the cutoff is 0, the color for that level is 80% of the maximum color in the gradient. If the value is 20%, the maximum volume will be 1000 - 20% = 800. In that case, levels with volume 800 will be the maximum volume color.
Upper cutoff V	The maximum volume. If the order volume exceeds the maximum, the price level will be the maximum volume color.
Contrast	Controls the contrast between the levels on display.
Large volumes	Sets the maximum value for every bar, with the last value in each bar taken the moment it is closed if this is not checked.
Brightness	Filters levels from smallest to largest. The higher the brightness, the easier it is to see weak levels.
