Failed to call method 'Initialize'

[daven]

I downloaded an indicator from a forum which appears to work just fine. the code is open and I can look at it. However, I keep getting the following message in the log file:

"Failed to call method 'Initialize' for indicator BTAutoPivots.' Object reference not set to an instance of an object."

What kind of thing should I be looking for in the code that might cause this kind of message? It doesn't seem to be affecting the performance of the indicator itself but how would I know. other than it doesn't work at all?

I'm adding the first part of the code and it clearly does have an initialization section.

Thanks

Dave, the Initialize() you posted looks ok to me - is this part of any chart template / workspace? Can you please try if you see the same error in the log if you load the indicator in a fresh workspace and on a fresh chart?

Thanks

I will try that later today and see what happens.
Thanks
