I was a subscriber for about eight months. I cancelled my subscription only because I decided swing trading wasn't for me, as it was only useful for EOD filtering. The program is pretty well thought out and very user friendly. You can perform some pretty basic easy-language programming, as well as advanced input for screening stocks. It has a healthy database of pre defined pattern recognition, as well as a public forum for member supplied strategies, and most are rated by users. At the time I think it was about $9.00 per month, so it won't break the bank. I am not affiliated with them in any way.
