Embedded Indicator and CalculateOnBarClose

[Stopped]

Hello,

Let's assume we have two indicators X and Y where the first one is set to CalculateOnBarClose (COBC) = true and the second one to COBC = false. If X is embedded in Y, does that mean that X would now run as if COBC = false?

By the way, I stumbled upon an old thread where you said there was a bug related to using the COBC line on any indicator that is embedded (see http://www.ninjatrader.com/support/f...7&postcount=20). Has that bug been solved?

Thanks in advance,

Hi Stopped,

CalculateOnBarClose should be assigned a maximum of 1 time in the calling script only. If your script A calls other scripts B and C, scripts B and C should not have any COBC assignment within.

Thanks RyanM,

Just to clarify, regarding my first question, if A calls B and A has the COBC property set to False, would that mean that B would now be running with the COBC property set to False too?

I am asking this because I had developed an indicator that was running correctly when calculated with COBC = True, but I am getting wrong results when I embedded that indicator into another one that is running with COBC = False.

Thanks again.

Yes, you can have unexpected results and your indicator may not work properly if you assign COBC in called indicators. There's no answer here other than to follow this as best practice.

Since you can always assign COBC from the indicator GUI, its assignment in a script should be avoided as often as possible. Assign only if the design of the indicator requires it, or you want to save time setting it via code while testing.

If you need to combine parts of your script with COBC = true/false, this sample offers the recommended approach.
