I use a Slow Stochastic of 14,7 as a good indicator for swing trading on the daily. Its showing right now that its coming down from being overbought and is still some ways away from being oversold. This is when the %D of the slow stoch will be near the 20 level, its at 61 right now and moving down. However, the %K value is at 34 which is nearing oversold...
Cheers!
