Histo type indy for mtf ma

I thought this might be a nice idea for an indy if a coder is sitting around with nothing to do(ha ha)--or if it already exists can someone please post.
I know there are other ways to get same result but--
Block type histogram. Inputs--ma type, ma period,timeframe, line height(so they can be stacked) It would show green for bar close above ma and red for bar close below ma.
Any help really appreciated.

If I want to see on a 5 min chart for eg where the 10 ma is on a 15 min chart I thought I could just put a 30ma on the 5 min---ie 3 x 10 --but this doesnt work--why not?
Sorry for dumb question
