Apirine Slow RSI [LazyBear]

The slow relative strength index (SRSI) indicator created by Vitali Apirine is a momentum price oscillator similar to RSI in its application and interpretation. Oscillating between 0 and 100, it generates both OB/OS signals and midline (50) cross over signals and divergences.

As author suggests, bullish/bearish divergences generated by SRSI are not as effective during strong trends. To avoid fading an established trend, the system is used in conjunction with a trend confirmation tool like ADX indicator.

You can configure the OB/OS levels, default are 70/30.

Good for day trading
Looks good LB. Thanks for sharing it and all the other indicators that you provide to us. By the way, I have looked for a Time Series Forecast indicator in the scripts and have not found it. Do you know if it exists? Thanks again.
Thank God the Ehlers flood is over ;>)

Ehler's stuff is quite good if used with some common sense :)
