Your decision needs to be aligned with how you set your limits and expectations and not by just following your emotions which most of the time been dominated by greed and aggression.
If you doubt things are as you say my friend, I think that first of all we as humans, before we are traders, market speculators, even investors, well we should be people who should imagine all the scenarios, if we play badly it is lost money, but if we play well we double the money, but at what price will we take that risk? Are we in a position to take that risk? We should imagine the worst scenario which is to lose all the money, and if possible, what should we do next? If we have an alternative plan that does not affect our lives in an impressive way, then we take it, but if not? What would we do? That is what before playing we should think, analyze and decide how far we can risk , for me that is playing intelligently.
