Product Description

Polynomial Regression Channel

This indicator will automatically curve-fit a polynomial regression channel. The user may select any polynomial factor between 1 (a straight line) and 6 (a complex curve). 

- I recently purchased the Polynomial Regression Channel and Sniper Trend studies and applied them to 5 minute charts for day trading purposes. In the first week, I have had great success using these studies.

I am really finding both studies useful and profitable.

aka The finest polynomial regression channel available for ThinkorSwim

I was wondering if you might want to attempt coding a Polynomial Regression Channel for Thinkorswim. I’m a huge believer in channel trading, but there has been nothing adequate coded for TOS to date. There are some poorly coded pseudo-channels on the net, but they are copies of each other and they have the same flaws.

This was a fun, although very challenging, project. I needed to study up on linear algebra so that I could understand the math involved. Then, because ThinkScript does not support arrays, matrices, or easily storing data for future reference, I had to devise creative work-arounds to handle the advanced algorithms required by this indicator.

This indicator will automatically curve-fit a polynomial regression channel. The user may select any polynomial factor between 1 (a straight line) and 6.

Questions

Was this made with a T3 Moving Average or a Centered TMA with an extrapolation to the right?

No. No moving averages are involved. This is a true polynomial regression. The curve is fit based on the closing prices of each candle.

Will this work with Heiken-Ashi candles?

Yes. It will work with any chart type (tick, candle, Heiken-Ashi, etc.) and on any time frame.

Below is a screenshot of a Heiken-Ashi chart.
