I decided to see how strategies will work on BNB pairs, but for some reason MoonBot writes that I have zero BNB balance, although I have about $100 in BNB. Meanwhile, the parameter on the main window shows BNB: 0.34. Can you tell me what the problem is?

You have autopurchase BNB set up for the trade commission and MoonBot has autopurchased BNB on your available balance.
Go to Settings – dvanced – Engine settings. Uncheck “Auto buy BNB” option. If you want autopurchase function, set “Min. BNB level” = 0.10 and “Buy BNB” = 0.10, i.e. if the number of BNB decreases less than 0.10 MoonBot will automatically buy only 0.10 BNB more each time.
