thank you, and it's a good example of why trading is not black and white like a math equation: There's all sorts of variables that come into play depending on trading style, goals, risk tolerance, emotions, etc - all these decisions one has to make that can be difficult at times -  and you have all that human emotion coming into play to cloud your judgement 

to me it's always far easier buying into a position than it is exiting/selling - exiting is always the toughest part, where to exit, exit all, exit part etc
