out of experience and practice comes this: talking about average events (most frequent events that happen) before comes a certain loss there is a chance of recovering it during a session. After this limit is over, and you get loss again there is most likely no chance to recover it, you will go down deeper and deeper almost for sure. You have to figure it out with practice and experience, you have to get feeling of it to know. It takes time and patience. And you don't always have to play real money.
