6 years ago I purchased the camarilla formula to daytrade bonds...I made the mistake thinking it was the Holy Grail of high and low predictors.

I now use the formula to get the "zones" for the next day...I use the high,low and close from 8pm EST to 8pm EST to get the levels to trade...for a long entry...if price goes below level 3 but not level 4 I will buy a pip above level 3 and place stop below level 4.

Reverse for sells.

I am told that price exceeding level 4 is a breakout buy/sell.

Currently I am working on finding an earlier entry for buys/sells in the level 3 area that get me in before the price goes over/under level 3 again.

Formula for camarilla is in one of the threads here also.
