Well, this is a question that i have encountered most of the time...specially after a nice profit and then losing it again. We all make profit at some point of time but we cannot sustain it, sooner or later we end up losing it . I think we should know when to stop..but then the question again, how? There is no direct answer to it, it can be learnt only through the conscious observation of gameplay over a period of time. No matter how we play, but once we gain some profit, we must be attentive to our behaviour..i.e. how we react after winning that causes us to lose. Somebody said correctly..."its not your loss, but how you behave after winning that decides your fate"
