ADX Defining PDI/NDI

[chrisf95003]

Hi
I am trying to setup an ADX indicator that changes colors when the NDI/PDI get out of line by more than 10. I am not sure where and how to define the PDI/NDI variables. If someone could take a look and tell me what I am missing that would be great.

Thanks,
chris

The attached revision will paint the ADX line in green if PDI-NDI >10 and red if PDI-NDI<-10. Compare it to the one you posted to see the differences.
It is unclear to me if you want to also plot the PDI and NDI. If not then replace the return line with return vADX.getValue(ADXDMStudy.ADX);
Hope this helps
Alex

Thats perfect.

Thank you, Alex.

PDI-NDI

Alex:

The script you wrote (pasted below) seems to work well for me, however I have been trying to convert it to a "paintbar" with no success. I have tried by copying and pasting from other "paintbar" formulas burt seem to be missing a key variable. Could you help? Thanks Alex, your work is tremendous!

Use as an example the conditions in the efs I attached to a prior post and replace the setBarFgColor() command with setPriceBarColor(). For the syntax required by this command see this article in the EFS KnowledgeBase. Also listed in that same page are two other commands that you will need to add to preMain which are setDefaultPriceBarColor() and setPriceBarColor(). Follow the corresponding links for the required syntax
