IB offers top % gainers and a multitude of other parameters through their market scanner. IB is geared to very active traders and their TWS platform is a comprehensive one.
IB charts are awful, however, so try using it in conjunction with QuoteTracker, an excellent charting application. The two together (fast executions at rock bottom prices/great charts) are a great combination.
Check out elite trader reviews of both for more info. Good luck.
