Are lot size's fixed for copy trading ?

Can you adjust lot size's for automated trades copied from experts on mt5 ? 

If yes, how would you go about doing so ? 

Thanks in advance, 

  1. Down by reducing the deposit load below 95% (max)
  2. Up by increasing your account balance vs. what the signal provider has. Signal lot size is adjusted from signal balance and leverage to yours.
