Holding winners/resisting urge to take profits: I always seem to get this wrong. If I take profit on a trade, it will then fly off relentlessly in my anticipated direction. If I 'let it run' it always hits my stop. Without knowing what the market will do, it's hard to get this part right.
That I agree absolutely. Let profit run and cut loss sooner is almost impossible to do in real trading because you never know whether the profit is going to be there when you take it in the future and once you cut the loss, the loss might turn around and erase itself and become a winner instead.
