well i haven't used this indicator that well to really know how powerful it is, but i beleive its not when it crosses 15 or 25 that you need to take a trade, to be at the safes place of making a good trade you need to make the trade after the peak has crossed and closed down, that way you are sure to make good profit, also, use on H1 or H4. Also you can reduce the len to something like 50 to accommodate more signal and av ery good one.
