Among others rsi, ultimate osc, slow stoch, wm%r, but picking the right indicators is not enough... I'd recommend reading Technical Analysis for the Trading Professional by Constance Brown. The author's got a very nice way of explaining how to read signals and what settings to use. I for instance use different settings for different timeframes, especially with forex charts.

The best is to try them out and see what works for you. Try to see patterns and write them down. You can make some trades on paper, based on the settings that you wrote down and then see what your success rate is after a period of time. Settings are never optimal, they continuously need tweaking...
