Step Size Part allows setting distance between commands DCA. 

• Step Mode: There are 5 options to set step calculation for DCA instructions.

• Fixed Poinst: fixed by number of points.

• Last Distance: calculates the step by the distance between two preceding orders. Unlike Fixed Points, in this mode, the distances between orders are not constant. With Last Distance, the spacing between two orders varies. For this mode to work, there must be two initial orders entered from the Entry tab. Only then can the distance between the first two orders be calculated to function as Last Distance.

Trailing: Calculates the step based on the distance between the entry point of the previous order and the current price (when the price moves against the direction of the previous order).
