copybuffer error 4807

[mcronline]

Hi

Trying to use copybuffer for some indicators, but it is returning error 4807 when running. I tried it for stochastics and Adaptive Moving Average, with the same error. Could only make it work for the Simple Move Average.

Thank you

I was defining the symbol the wrong way

changed to:

string name = _Symbol;
