FAQs :

1. How to remove symbol prefix from my symbol when sending order to binance? if symbol prefix is a_BTCUSDT, when sending order via API you should send “BTCUSDT” only

here is the script tutorial to remove prefix from your symbol

void OnStart() {

   string sym = _Symbol;
   string prefix = "bs_"; 
   int length = 3; 
   string resultString;


   if (StringSubstr(sym, 0, length) == prefix) {
      
      resultString = StringSubstr(sym, length);
   } else {
      
      resultString = sym;
   }


   Print("Original Symbol: ", sym);
   Print("Result String: ", resultString);
}

2. I am getting wrong Lot size calculation while calculating lot size for my EA, I use Google to calculate USD rates. What I am doing wrong?

You should calculate Lot size as per Binance rules only. Here are links to Binance Leveraged Margin Table which mentions Maintenance Margin as per your position size. You should deduct Maintenance margin from your position size. Also you must be interested in Liquidation Calculation logic to be implemented in your EA

Example : First go to Binance App and select leverage you wish e.g. 125x

then lets suppose your account balance is $33.69 and BTCUSDT price is 59169.3

then check how much qty you can buy, in this case as per price in screenshot you can see I can buy 0.071 max qty

so make sure your calculation is either 0.071 or below then your EA will be placing order without any issue.
