I have two panels.
One with the price (OHLC) and a moving average, and one with the volume.
I want to create a middle panel with to oscillators that oscillate around zero.
Each oscillator is the difference of two moving averages of the chart above it.
Is it possible?
Thank you.

I have managed to create the middle panel with the two oscillators, but I can't change their color.Any ideas?
