Description

Hello.

Are there any way to change volume bar colors by comparing consecutive volumes, not by prices?

If today's volume >= yesterday volume, GREEN volume bar
If today's volume < yesterday volume, RED volume bar

Thanks.

Research direction

Start by tracing mplfinance's existing volume-bar coloring behavior and how it compares prices; the issue does not name a file or test. Done means consecutive volumes are compared so bars are green when today's volume is at least yesterday's and red when it is lower.
