Quote from FCXoptions:
Do you get to watch the market all day or at least occasionally check your positions? If so as soon as you are up raise your stop loss. Use it to guarantee your win. Ive started using them on my option trades and walking them up as soon as it's a winner. Makes me 10 times more comfortable with letting my trade run for longer in case the market reverses faster than I can place a limit order.
moving stop losses to break even is a good idea and i implement it sometimes, not as much as i should though
just i get greedy thinking if i bump the stop loss get stopped out and miss the next big wave
