Can anyone assist in pointing me in the right direction for creating a scan criteria in tradestation for finding options with "unusual" activity. Like large block trades or higher than normal trading activity. I am currently using "Opt Volume > Open Interest" which does a decent job of finding some new large openings but I think its very limited as obviously there are going to be some larger and/or more actively traded equities with options where there can be unusual activity and the volume would not exceed the open interest.

Thanks

Where can you scan for this in tradestation...the regular scanner or the scanner in options station pro?
