Issue with using Add() in NT7 Indicator

[trader3419]

After having used
Add(PeriodType periodType, int period)
In my NT 7 Indicator.
When I switch symbols a few times from EURUSD to EURJPY etc.
Eventually my chart becomes blank.
Is there something I should do after I finish using Add?
Do I need to dispose of the BarsArray?
Thoughts?

Hello trader3419,

Thank you for your post.

There should be no need to dispose of the called instrument series in this case.

Do you receive an error on screen? Are there errors on the Log tab of the Control Center? If so, what do these errors report?

I look forward to your response.

Thanks for your response.
I actually got no errors but a few pairs were blank if I changed to them.

Keep in mind that I overloaded the dispose function.
Also once I disposed of those instruments I stopped getting blank charts.
I just added in BarsArray[1].Dispose();
BarsArray[2].Dispose();

Even though I stopped getting the issue, is there any reccomendations you have?

Hello trader3419,

Thank you for your response.

I would not have any recommendations here, I am glad that you found a solution here though.
I will test and report this unexpected behavior as a bug.

Add(PeriodType periodType, int period)

What PeriodType and value are you using here? Can you copy and paste each Add() used?

[trader3419]

Add("$EURUSD",PeriodType.Minute,5);
Is an example.
Also a 10 minute one

Hello trader3419,

Thank you for your response.

Do you have a workspace that you were testing this on that I may test?

You can send over your workspace by going to the Control Center-> Help-> Mail to Platform Support-> ensure the Workspaces option is enabled.

I don't have the ability to upload my workspace at this time.
But I am positive the issue arises from using Add() in the initalize function.
while overloading the dispose function.
and then switching around pairs a few times (I think the same pair you added).
Then eventually that chart goes blank while on live data

Hello trader3419,

So disposing resolves the matter or causes the matter?

[trader3419]

overloading the dispose function without actually disposing of the BarsArray[1] and [2]
Is when I had the issue.I was only disposing of other things not the BarsArray.

but once I added in the 2 lines of code to dispose of BarsArray it fixed the issue

Sorry if that wasn't clear

Did your overloaded dispose call base.dispose()?
