With the last update to my message, I now seem to understand what the problem is with combo bot grids.
Combo grid’s high and low price and the volume are defined by the DCA settings. The amount of minigrid levels
is configured to be the same for all DCA minigrids. That way we can easily calculate the volume per grid level by dividing the total amount by the number of grid levels.
(Alternatively the calculation of the volume could depend on the percentual deviations.)
If we instead define a geometric spacing the minigrid levels couldn’t be the same for all minigrids since we require more and more levels the lower we go.
