if you zoom in on the adx crosses you will see that by the time they crossed the drop was near enough finished and ready to move back up again...thats the trouble with indicators...they lag price action...
Only to be used imo as a confirmation of what the price action has already been indicating...its the same with macd as a trading signal...by the time it crosses its too late..its only use is to get a feel for longer term directions in daily and weekly time frames
just my two penneth anyway...
