Simple EFS question

[Himalaya]

Here is a screenshot of Dloomis's "Cumulative Bid Ask Volume"

Along with the code (that I have tweaked a little)

Why does it not plot in LIME and RED?


Thanks in advance.

Hello Himalaya,

Change premain() to preMain().

Thank you David and Jason

Thanks Jason for the fix.

And David for the study.
