comparing instruments

[brucelevy]

Hi what functions can I use to begin comparing %chg between two instruments in a strategy?

I would like to also plot a %chg line chart if possible.

Hello brucelevy,

Thank you for your note.

You could use CurrentDay OHL to pull todays open, then take the difference between the last and todays open divided by todays open,

Or you could add a daily secondary series for both instruments, then compute the difference between yesterdays close and todays price, then the difference between the two.

You would use closes under this approach,

To add a plot:

Either of those two methods could be used to accomplish what you’re looking to do.

The following sample on the forum you may also find useful,
