Although the parameter menu for setting the bet amount limits the stop loss/profit to stop the game play automatically after reaching it, you don't know the chance of winning in each session because the program works automatically without you monitoring it on the PC screen. Besides, I suggest that you should limit the money in gambling and the system of the casino may be able to detect bot applications so you need to learn the terms and conditions because some online casinos do not allow bot users.
I'm referring to the built-in game settings. I also used a fixed chance of winning every time I use automated bets. I don't use bot scripts that need to insert into the code system, I am aware of the risk of using it generally. That's why I use automation bet settings to make my play faster so even if I don't monitor it, I can see the results when it stops.
