Hi, is there a way to write a condition formula for use in either a watchlist, or better yet a scan, where the premkt Bid is compared with the close of yesterday? For example, the premkt Bid is 8% higher than yesterday's close. Another example would be the premkt Bid is x% greater or lesser than yesterday's close, and I could put that as a watchlist column and sort by it.

Also, can premkt volume as a pcf  condition, again for use ideally in a scan but secondarily in a watchlist.

 Thank you in advance for your help.

No, it is not possible to include bid or ask (pre-market or not) in conditions of any type in TC2000. There is no way to reference the bid or ask in the Personal Criteria Formula Language.
