RE: How to create the Mansfield Relative Performance Indicator

I believe the original Mansfield Relative Strength used a proprietary method to do the calculation, as it used a weighted MA for the zero line, and was also based on the DOW or NYSE, and not the S&P 500. So you won’t get an exact match. But using the 52 week simple MA of the relative performance of the stock versus the S&P 500 is the best approximation these days imo, and the board literally has thousands of examples proving its use.
My research over the years has found that showing the zero line as the actual moving average on the chart gives an extra vital piece of information, as if the stock goes above the zero line when the zero line itself is still declining, then the chances of failure increase dramatically. And this was confirmed in a brief Q&A with Stan a number of years ago, and has now become one of the breakout checklist core rules. As A+ breakouts almost always occur when the relative performance zero line is either flattening or rising. If it's still declining, then it's usually a red flag.
And so you can't see this extra information with the flat version of the Mansfield RS, and hence why I show the version with the actual MA slope in view.
