Invalid condition?

[John833]

Hi
I seem to have a problem with one of my conditions…

If DonchianChannel(14).Upper[0] - DonchianChannel(14).Lower[0] > 10


For some reason this does not work, but everything else does in the script without any error in the log.
Is this an invalid condition or have I written something wrong?

Thanks in advance

What does not work?

- Does not compile?
- Condition never is true?

[John833]

Yes it does compile and it does run, however the condition is always true, even if the difference of the DC is less than 10

I don't think this is possible. You will have to debug to see what is happening.

For example:

double difference = [FONT=Arial]DonchianChannel(14).Upper[0] - DonchianChannel(14).Lower[0];[/FONT]
[FONT=Arial]Print("Difference before condition " + difference);[/FONT]
[FONT=Arial]if (difference > 10) Print("Difference after condition " + difference);[/FONT]
[FONT=Arial][/FONT]

[John833]

so are you saying that this condition should work?

Is it important to Add this in Initialize()?

[NinjaTrader_Ray]

Yes, it will work and the code snippet I provided would be a debug test so that you could verify it. This will not work in Initialize(), you need to check for this in OnBarUpdate().

Thanks for your help...

Ray, I found the problem, I should have been looking at DC 1 bar ago not the current bar.... I think... just testing it now....

Thanks again for your help
