this thread will address another neat little trick i use in scalp trading.
Let me play Devil's advocate for a moment or two (trying to generate a useful discussion not to knock your posts!)...
I have a real problem with this type of 'rule' as if it is entirely empirically based (I assume it is?) then it requires some pretty clever analysis to demonstrate any value or not.
"Pretty clever analysis" is not posting a few charts that show
when it works
so long as you give it a few pips leeway.
I am especially skeptical when the distance between levels is not >> the error that you seem happy with as a successful application of the tool, it is very easy to 'squint' and see all kinds of magic! I know that no tool is perfect but that isn't a valid argument to assert that it does have value (which has to be the key test).
Even any replies to this thread are likely to be 'self selecting' as there is undoubtedly a bias towards replies where it has worked compared to cases where it hasn't.
(Still being Devil's advocate...) I would even go as far to say that unless there is a proper piece of analysis to back this up (the trading equivalent of the double-blind placebo-controlled drug trial) then it is about as useful a post as me telling you about my tool that requires the averaging of the temperatures in NY and Tokyo at market open and close.
As I say, just being healthily skeptical and treating everything with the caution it deserves. Note also, I wouldn't have bothered writing this much if I though you were just barking mad!
