# DOM Trading

H4 supports direct trading from the DOM for users who want tighter price control and greater execution granularity.

The chart can be transformed into the DOM from the chart bottom-right controls.

The DOM price ladder grouping is configurable below the ladder, which lets the user choose price precision.

A single touch on a DOM row places an order at that row’s price.

If one or more orders already exist on a row, double-pressing that row cancels all orders resting at that price.

DOM order size is controlled by the same size input used in the controls section.
