This has been working fine, then on Thurs 27th, I repeatedly got the following report.
I am using Windows10
It tried to trigger one of the indicators. then produced the above instead and disabled the tick from the " Last Pattern"
(The same exception appeared at the same time on a different machine running Windows7 operating system)
Here is a screenshot of my settings.
I had ticked ALL the different pattern, but feel it was a ''Crab' or ''Shark' that it didn't like
It occurred on my 10 minute chart
