Here is an example of the KISS method : we use the same indicator (RSI) with different parameters to confirm the trend and the timing. The advantage is that you have only one indicator to master to get your system. Of course you can use DMI, MACD or something else to confirm the trend, and Stochastics or whatever oscillator you want to get the timing. But here we have only one indicator to get the whole and it is true it could be an advantage (dixit my bro').
