Folks - New to the market - using Ameritrade account with their add-on Level II etc. Looking at other options - all very pricy by comparison. Most importantly - what software gives the ability to find premarket equities meeting certain conditions. For example - list of stocks that gapped up or down more than $1 in premarket activity Any recommendations?? Is it possible to do this with Tradestation? eSignal? Others for a new trader....??? Thanks Rob
