but if this 3rd bet or round is eventually in the money, this way you have recovered not just your capital but also have made some profits 2x your stake $15x2 - $30.
Now, it either you take a leave for next day or wait for the next round if you would want to continue betting.
Ensure you have a target profit amount and loses amount your willing to take, and the way I approach it, whichever one that I hit first, I turn my system off and leave for the next day.
When I've lost for a while and somehow magically I start winning, if I'm just starting my gambling session it doesn't bother me currently as I've learnt this gamble in moderation, so I have the funds I'm prepared to either lose or multiply as the case may be.
The only exception is when I'm about ending my gambling session and I stumble on such win that recovered my losses and gives me an edge or profit for the evening. I'll want to end the session smiling and withdraw the profits for a bottle of beer or two. At such situations, I'll quit immediately and arrange myself for little merriment.
