I think I might have asked this question before (or seen it asked), but never really understood the answer.
I'm getting a bad historical bar from Barchart, and it's throwing off my back-testing. How do I fix it..? I have the real-time filter on; wish there was a way to apply it to historical data.
Maybe someone could take a look and see if they're seeing the same thing. PNC, 3/6/2009, 1 minute bar, about 3:52 PM. I have one bar that drops down to 16.1. That price never crossed in real life (or my filter blocked it out), thank god.
