Quote from dagnyt:
I believe most traders would have better results if they ignored B/E.
Once you own a position, it's your job to manage risk and exit the position at an appropriate time. That exit point depends on risk/reward, probability of earning money if you hold etc.
But the one thing that does not matter - is the price you paid to own the position. The position is either good to hold right now, at today's price, or it's not. Nothing else matters.
I know that's a minority view, but it's the correct stance nonetheless.
