travisdu's discussion of the opening price principle prompts me to inquire about the screening feature which sorts out those stocks which have historically either gone up or down at least $1 or $.50 or 2.5% from their opening price over 80% of the time over the past 20 trading days. Big Easy has such a screen. I was using it with over 80% success trading $1 bulls back in the spring, but this market gives no hits for $1 (still plenty of $.50) and I got the feeling that's it's too good to be true. Also, anyone can do it, the only premise is purely statistical probability. Has anyone used it? Would appreciated your thoughts, opinions.
