Hi MrTools, can you please modify the attached indi as per pic. You did modify it before but it draws histo irrespective of where the fast and slow positions are. In essence it is correct but what i would like with this new modification is to :

Only draw red hist when red fast period is below red slow period.
&
Only draw green hist when green fast period is above green slow period.

Hope pic is clear..i have attached the original indi and the histo indi you created from it(hopefully will be easier to edit it).

Any help will be greatly appreciated.
