Anyone Amend this Indi for 4Hr Instead of Monthly?

Is there anyone that can changed the attached ind so that it shows the High & Low of 4hr bars instead of Monthly ?

thanks Stan

i dont think MQL4 can work in the updated mt4 600

I'm still on version 509, so this indicator is working OK.
I just need it adjusting to show the 4Hr high & low levels, so it's easier to see possible entry points on the lower TF's.

thanks Stan

Simply search/replace all month related time frame constants to H4; namely PERIOD_MN1 to PERIOD_H4 and its respective minutes value 43200 to either 240 or (equivalent) PERIOD_H4.

Thanks for the advice Rockit.
Made the changes and it works a dream

cheers Stan
