Need to program a good idea of trend indicator

Hi all
Need rectangle histogram indicator that shows three colors:
- when price is above upper bollinger band
- and when under lower band
- and when between the two bands

I use this method to identify trend direction with high degree of accuracy when using H4 & H1 at the same time and i use bollinger standard dev. 1.0

Thanks alot in advance

Do you mean one of those indicators that puts different colored bars in a separate window?

yes Neutralizer this is what i mean

Hi all
The attached indcator is exactly what i am talking about but it gives only two colors ( when price is under lower band and it changes color when price goes over uper band )

We need to insert a third color when price is between the two bands

Can somebody help with that

Thanks alot in advance
