Used madscan. Its okay and will do just about everything. Have a few issues with their servers going down. Went down the last three days in a row. Unacceptable in my opinion. But it is a good program. For the price you cant beat it. Has alot of features but its not geared toward scalping. The developers are more programmers and dont quite understand exactly what a trader wants in a stock screener. I know use StealthAlerts. This program is unbelievable. They can program any trade idea you have into a ticker. This program is more for the advanced traders in my opinion. For stock screening nothing beats it. One of the coders/developers worked at a trading firm and knows what a trader wants and needs. And you cant tell once you use the software. If you have ever used Insight then you will feel at home with Stealth Alerts.
Ditto on StealthAlerts. Been using it for some time now and love it! I challenged Madscan and Trade Ideas to create the same rules for me that I use in Stealth Alerts and they couldn't do it. I guess you get what you pay for.
