Hey Gringo... not losing me at all. What I found was that a line break is of course a much worse reason to exit and when I was drawing lines in too tight, they broke far too easily anyway. Then I started to use previous swing points (dropping the lines along the way), and this works much better, but of course you're still caught when you exit sometimes only to see price shoot back in your direction. Now I think that the best thing to do is watch how price reacts to that swing point that you're using as a way to figure out if buyers or sellers are in charge.
Of huge importance is knowing where to put your trade on. If you're trading in the middle of a range or chop, this all gets quite messy, and trades that are stopped out might still be great with-trend trades and you're simply caught in consolidation. But if you focus on trading at the extremes, which could be either channel extremes or levels you get from hourly/daily charts, then things get a bit easier because these entries either decisively work or they don't, and hence the stop will either never come close, or the fact that it does is a big clue in and of itself. Add to this the importance of figuring out if you're trending or ranging, which is part of the whole process of prep, and things get less cloudy.
I will say this though. The hard part is translating having a backtested trading plan with knowing what to do when and where based on the market. For me this means that things are firm, that rules are firm, which fulfills the first part, but watching what the market is telling you seems in some ways "lose". As you say, stop losses aren't a "pick-a-stop-loss" kind of thing, but are in some ways fluid. So once you introduce some amount of variability or the idea that "it depends", then you get really lost for a while.... at least I sure did.
