How do I filter out a strategy if, for example, buyer volumes have started to increase, which could indicate buyer interest in the coin and lead to further price increases?

To do this, you may activate the UseBV_SV_Filter and check the box (YES). This is a buy/sell ratio filter. This parameter is only taken into account when auto-buying is enabled in the strategy. Then set the value in BV_SV_FilterRatio – it is the ratio of purchases to sales either for a specified time N or for a specified number of last trades, below which autobuying is not performed.
Example: given N = 60 minutes and BV_SV_FilterRatio = 2, the coin will pass through the filter and the strategy will work if during last hour the amount of buying was at least 2 times bigger than the amount of selling, that is, for example, if you sold 1 BTC during an hour and bought at least 2 BTC.
