Why not cut your losses earlier, not only do you risk getting stopped out but you tie up increasing capital in a losing trade so you can't use that to take another trade so you end up losing 3 times, once for the tied capital, once because of not taking a trade in the right direction and once when the price moves back to your original entry.
Think about that, and cut your losses a lot earlier.
You end up paying a lot more then just the loss for holding on to losing trades. Even getting out at BE is still a loss.
