As you know that you need to stop and leave the game? How can you feel this moment. I almost always lose their money because they can't learn when to leave the game. I'm not sorry to lose. I have a lot of money not to lose, but I can't keep the winnings if I'm lucky.
For me the time to leave is when I've lost half of my bankroll. That's a signal that I've gone too far and at least I still have half of my money.
