The AccumulationDetector indicator calculates the current volume profile over the period specified in the settings, provided that the zones are close enough to each other, and statically displays the Volume Area zones. The closer these zones are to each other, the higher the volume in this range, and consequently, the volume distribution will have a more impulsive character.

In the settings, you can choose the time frame for building the volume area. There are no specific guidelines on what period should be used for a particular working time frame, but you can refer to the following recommendations:
