My work says if it retraces to 4 then chances are we've seen the low, so that's where my stop is now. Coincidentally, it corresponds to my b/e point for today.
Regardless of what happens today, I think situations like these are where my trading could improve. Such a critical point is perhaps a good place to partial out 1/3. What I have found though is that partialing out is a trade off: you get a more stable equity curve but less overall profit in the long run.
The up trend channel is broken so now all it has to do for me is get under Friday's low (27) and I can hold overnight. In such a scenario I would keep a stop over the nearest s/r level that risks no more than 25% of profits from today. I actually haven't tested this holding overnight part, it is just a rule I made up.
It's a mini-hinge... which can lead to a decent move either way. I'm just gonna sit tight. At least for the next 60 seconds.
