Weinstein Relative Strength Clause???

I've got a relative strength indicator on my charts that I took out of Stan Weinstein's book that I think is based on the Mansfield Relative Strength indicator. It's the price of the stock compared to the SPX on a 52 week average I believe. Anyways, I am wondering if there is a way to include this in a scan somehow to catch stocks where this RS line has been trending up for at least a month? I've included a screenshot of what I am talking about.


  • The Price Relative/Price Performance indicator on Stockcharts is a ratio of the per cent price change for each symbol from the first date on the chart (when there are no indicators, the first value of the RS line is always 0). You can add overlays as you have done. It may be worth noting that the values of the indicator will vary depending on the starting point of the chart, but their relative position is unaffected (so the same data point will remain on the same side of the MA regardless of the chart start date).

    Unfortunately, you cannot scan directly for the slope of the MA.

    One workaround might be to add $SPX to you stock lists and scan the list with a rank by statement for percent change for the period specified - e.g. a month, or twenty days. Save the results in rank by order. Symbols that are outperforming the $SPX over that time period will appear on the list above the $SPX.
  • Thanks for that. I'll give it a shot.
  • I'm interested. Please chow code.
  • The rank by statement has to be the last statement in your scan. Then add the PctChange function with your chosen parameter. So,

    [some favorites list] // select a favorites list from the drop down on Workbench, be sure list includes $SPX

    rank by PctChange(20, close)
