Migrating an Indicator from 6.5 to 7

[zark.be]

Hello

i'm having a serious issue with an indicator i made for 6.5 and that makes 7 crash.
Since i don't have symbols i can't really look more into it.

I can send you the indicator by mail so you can test it . Its pretty basic, works on its own. But when used from within a strategy , it just crashes ninja.

Hello,

What ticket number did you get when you sent in the note to support as I do not see it here. We would need to test this with youy NinjaScript.

I look forward to assisting you further.

I just sent it now.

Hello,

Got it, I will look into this and get back to you via email.

Thank you for your patience.

zark.be,

The issue is that your code uses this line:

uOHLC = new UOHLC();

You do not need the "new" in there. Just do

uOHLC = UOHLC();

indeed that solves it. force of habit
