GetBar throws error

[Sleeping Troll]

In this code block:

 
[COLOR=red]StudyBar = GetBar(Time[0].AddMinutes(-30));[/COLOR]
[FONT=Courier New][SIZE=2][SIZE=2][FONT=Courier New]Print(StudyBar);[/FONT][/SIZE]

[/SIZE][/FONT]

I get an "Object reference not set to an instance of the object" thrown by the line in "Red".

This script errs when Time[0] = 9:04. There is a Bar at 8:34.

Further investigation shows that this is the first Time[0] that is an even Seconds (9:04:00) I think perhaps that is the problem, but I can't understand why?

Ran it again and time[0] was 9:04:01!

I am at a total loss... Please help!

Sleeping Troll, please keep all discussion for the same topic on the same thread. Perhaps we can test this on our end. Which instrument are you using and what time frame?
