Like using the pullback bottom as the stop loss level, and trading with the trend? Sure, its a great method and how most traders do it, afaik. The problem from my perspective is that pullbacks come in many waves. Waves counted by V bottoms (in an uptrend). By that I mean a HL-LL-HL formation. So maybe after the first V bottom in a pullback in an uptrend, I go long, place my stop just below that V bottom expecting continuation. Then price makes another low (or a few more), then goes on to make a new trend high. This is why I got away from using PA strictly for entries, and see trendlines or MA's more accommodating and useful for pullbacks. I think you posted a chart earlier in the thread measuring a pullback with a trendline? On the flip side, if a trader wants to take little nips at the pullback, and okay to get stopped out a few times from a multi-leg pullback, I think that's okay. So long as they measure risk correctly.
I hope I understood the question correctly. Perhaps I did not.
