Hi, scalping_nickel ! I'm also very interested in pre-market stock screener, my strategy is based on big movements on pre-market, more than 20% up or down... if you are focused on pre-market price/volume movements than I guess we have some things to disscuss... So could you give me your email? Or drom me email to alex@dx200.biz . regards Alex P.S. I'm using www.tradingday.com to see pre-market movers.
