In the MoonBot terminal, on the Filters / Volume tab of the strategy settings, the UseBV_SV_Filter parameter is located: this is the filter activation parameter that takes into account the ratio of purchase volumes to sales volume. If the BV_SV filter is enabled, that is, UseBV_SV_Filter = YES, then the strategy strategy will work if the calculated BV_SV value lies in the range that is set by two parameters: from BV_SV_FilterRatio to BV_SV_FilterRatioMax.
In order for the BV_SV filter parameter to be checked by the strategy, you need to set IgnoreFilters = NO on the general Filters tab, and set IgnoreVolume = NO on the Filters / Volume tab, while a green vertical bar should light to the left of the Filters / Volume tab, which shows that this tab and the parameters in it are not ignored.
