How to separate Frustration and Emotions from your trading.

We all learn several techniques as a Trader, even we use same in stock, commodity and Forex or Future market, and those strategies have been used by traders since the inception of Trading, but why then they have been so successful and why we are not and the shocking answer is Frustration which brings emotions in trading that really destroy every mindset or change it for a while. Frustration can really of several type as not understanding the market price action or poorly time trade without knowing the result or reward of that trade making mistakes which could easily be avoided. Reason of raising this matter is the case that has happened to me just recently where I was stopped twice of my pound sterling trade and succeed only once but that does not patter. IF we buy and sell at the same place then It really frustrate your mind as all those several years spend in trading can really be of no use.
