Firstly, 100% of the credit goes to Greg Morris @ Stockcharts.com for the article detailing the concept and most of the settings/components. I've simply implemented his idea. I haven't sought permission from him, but given that he was open with the components of the indicator I'm assuming he's happy for me to go ahead and code this in pinescript. See the article...
This is my PSv4.0 enhanced version of Dr. John Ehlers' Zero Lag Indicator with I.P.O.C.S. that uses a novel EMA based error correcting technique. It accepts a floating point number for the critical period providing ultimate tunability in my version. What's visually appealing about this indicator is the crossover turning points are marked with highly visible...
This indicator consists of a fast and slow EMA (default lengths are 50 and 9 periods) and an upper and lower ATR band. When combined, this combination gives traders an accurate picture of both trend strength and direction.
Users can modify the lengths of the fast and slow EMA , as well as the multipliers and length for the upper and lower ATR bands.
This is just a script that will cover you if you like to use EMAs, I put three EMAs plus a still-configurable EMA 200 in case you use a different big value, say 100 or anything.
Enjoy!
