Can someone code this MTF Heikin Ashi, please?

I assume this might be a quick bit of coding but beyond me (I did try).

Can some one add 2 more next time frames to this, so it is a 6 time frame HA?

Thanks In advance.

MT4 doesn't allow more than 8 buffers.

This indicator uses already all 8 as it needs 2 buffers per timeframe (blue + red).

The only solution is to recode the indicator and plot objects instead of using buffers.
