OBV customizable source/reference (close, open, high, low)

New comment

Hello,


I would like to have an OBV Indicator that I can choose to add or remove from OBV based not only in close price but also be able to change it to open, high and low. Does anyone have this modified indicator that could share or even help me out on changing the attached code?


Thanks in advance.

Where have you added the input to specify that, and modified the code to do that?

You haven't stated a problem, you stated a want. Show us your attempt (using the CODE button) and state the nature of your difficulty.

We're not going to code it for you (although it could happen if you are lucky or the issue is interesting).
