Max open Deals used by the bot when backtesting

yes sure
Two things:

  1. requested to add this info in the backtest stats here
    Backtest - dynamic price - add max simultaneous deals stats

  2. if you want to get this info at the moment the only trick is to open a deal with 100 DCAs and set the the same % used in the dynamic price filter - then look at the closed deal list in the backtest
