Passamontes has done years of stats and research on it .He says the 233 level will get hit 90+ %of the time ..I entered today at 36 and exited at 49..the 233level.
As you get confident ,you can enter on the reversals which hit the levels sometimes to the tick....which just happened.
Price bounced from the upper 233, came down through the opening range (switching to bearish bias ) bounced from the lower 233 ,back off the opening range and now headed for the 382..
