How far are you willing to let price come against you? I find that when low points like that break there is often a pullback thereafter which there was albeit not a very large one. Of course not always does price pullback after low and high points break but I do find it to be common.
No set amount, just depends on what traders do with it. I don't think price ever traded more than a tick above my entry, which was basically the spread, though I might be wrong. This trade resulted in a very small profit, and then set up a long opportunity which is still alive, though I did take 1/2 the position off when price traded at the opening range high.
