I should be able to move this code to 5.5 but I still need a little help. Got most of it but got a little confused around the DIFF

CODE:

Second Question
Is there something in 5.5 that supports "AddScanColumn"

Thanks again for all your help....Ed

Hi Ed,

When starting new topics, please try giving it a meaningful title. "Little Code Help" is something widely requested, and in addition, you have already had a thread named exactly the same in recent past. Thank you in advance for helping forum members find what they need and organizing information better :)

No. We'd suggest calling your Fidelity rep and telling you need this function back in Version 5.

What exactly is confusing about the Diff? What is the .NET equivalent of Abs, or ...?

Moving Linear Regression Channel from 4.5 to 5.5

Didn't think anyone would be working today! Thanks for the reply. Sorry for being so vague, but would you code the above so I can use it on 5.5 my coding expertise is not there yet and I couldn't find any examples.

I will call Fidelity Monday about the "AddScanColumn".

I was hoping the checkbox would be add to the Optimization Variables on this release. It sure would be a nice feature. (Wealth-Lab .NET » Wealth-Lab 101 » Optimization Question)

Thanks for the Demo on VolumeOnPricePane, this is how I get most of my code.....Ed

That's how it goes. Thought I'd be finishing some other stuff today but got not enough inspiration for that. :)

Good. This request is becoming popular lately.

And mention this please too when calling Fidelity, this is a really convenient option that begs to be there.
