This indicator is called FXBS2. It is very useful on XAUUSD. Please look at the two pictures bellow,i want it to run like the "target" one,not the "now" one. please help me correct it!

Why did you post your MT4 question in the MT5 General section instead of the MQL4 section, (bottom of the Root page)?
General rules and best pratices of the Forum. - General - MQL5 programming forum?
Next time, post in the correct place. The moderators will likely move this thread there soon.
In the chart window, histograms are drawn via pairs of buffers. If the first is higher than the second, it uses the first's color.

In a separate window, histograms are drawn from the buffer value to zero. They are drawn from the first to the last. If you want one to be the background, it must be the first buffer.
