SMA throws exception

[liorsham]

Hi,

same SMA i've used in NT7 is throwing an exception now when calling
SMA(Closes[index], barCount)[0]

Closes[index].Count = 968 & barCount=20 , so no problem should be happening..
The exception thrown is:
"Index was out of range. Must be non-negative and less than the size of the collection.\r\nParameter name: index"}

Again, the exact line of code with the same parameters is always working in NT7.

Hello liorsham,

Thank you for your post.

Are you checking there are enough bars to load with CurrentBars?
For example:

if(CurrentBars[0] <= barCount || CurrentBars[1] <= barCount)
return;

Thanks. it seems that helped.
interesting though I didn't have to do it in NT7.
