Pfscan
Pfscan is a very neat and well priced (£60 one off)TA scanning/chart producing tool that can be used with several different data feeds including Sharescope, Yahoo, TC2000 and Metastock. Dave Baker the person who wrote it intially for his own trading needs, is constantly developing and changing it according to feedback from users and consequently the support is excellent.
A big plus, is that provided you can access data you can use the program on any market or instrument.
You can scan for stocks that may be about to reverse in price and the analysis part of the program will tell you how good a trade a buy/sell would make based on support and resistance levels. I tend to use this as the basis for finding my UK FTSE100 swing trading picks.
If you go to this link you can download it for a 30 day trial period free.

(PS I've marked it down one point on features because as yet it doesn't draw candlestick charts, just OHLC and P&F. But I have reason to believe that might change soon :))
