Min lot value

I have a question regarding lots sizes of us tech 100. Is there a minimal lot size in backtesting bots? Im coding my bot to take trades according to my risk = 100$ every trade, so my lot size varies from 0.3 to 2. However, my bot is not taking proper trades when lot size is smaller than 1. I want to connect my cBot to FxPro later, and their minimal lot size on nasdaq is 0.01, which should work fine, but ctrader backtesting is not allowing to take trades smaller than 1 rn
