I am currently using NexTrend Analsyis (http://www.nextrend.com) that has a nifty Market Scan utility. I currently have setup scans to display those trades that broke the 52-week high, another one to display those that broke the 52-week low, and another one to display those that are in either a crossed or locked market. These all are relatively simple scans on their system. I was wondering what other people use as criteria to scan or screen for when looking for interesting posisitons to potentially get involved with. Any suggestions or criteria you can provide me will be greatly appreciated.
