Any of you technical traders use Parabolic SAR for anything?
I just added an implementation of it to my AmiBroker plug-in and get decidedly poor backtesting results if using just that to generate buy and sell signals (based on daily prices). If I play around with the acceleration factor (ie. rather than just using the 0.02 value) I can sometimes get better results, but even then mostly poor relative to other methods.
If you do use it, how do you use it - by itself or in combination with other things somehow?
