Would some Coder Experts Modify this Great Indicator ?

I found this indicator is great and useful in 1M TF for trading...as the trigger or as the filter...

And if some great coders and programmers want to modify this...it wiil be greater and more useful than the original one...

So, the changing is like this..

If the current bar is lower than the precious bar, it becomes Red means Selling Area.
If the current bar is higher than the precious bar, it becomes White means Buying Area.
