HISTOGRAM BUFFER

[Rajesh Kumar]

 

Can someone please confirm how histogram buffers are used when writing custom indicator

i created line to histogram but the histogram repaints.

How do I relate the buffers to the histograms.

please help me.

#property indicator_buffers 5
#property indicator_color1 Yellow
#property indicator_level1 0.0
