Relative strength

Teknical

Hello, I need a scanner as in the image attached.
Conditions
Spx 500 Falls more than 5% in 10-days ,but the stock felt less than 5% in the same period which shows that stock is exhibiting Relative Strength . Please if anyone guide me how to scan for such condition .

Thank you

I think you probably should set this up as an Alert (or Scheduled Scan) for the SPX FALLS condition. Then when the Alert is triggered, run the "FALLS LESS" scan.

The Alert (or Scheduled Scan) code for the SPX condition could be

[symbol = '$SPX']
and [ROC(10) <= -5.0]

This would trigger the Alert when the 10 day Rate of Change is less than or equal to -5%
If run as a Scheduled Scan, the results would show "No data available in table" if the scan resulted in the condition not being met.

Looking at the ROC10 on the $SPX chart and putting a horizontal line Overlay at -5 shows this doesn't happen too often in the past year.

So once the Alert is triggered, or Scheduled Scan produces a result, you could run your "Falls less" scan

StockCharts.com has a PctRelative function in the workbench in the TECHNICAL INDICATORS dropdown.

PctRelative defaults into the workbench like this:

and [PctRelative(20,$spx) > 0]

It's asking for the percent change relative to the $spx in the last 20 days to be greater than 0. So if the $SPX went down 5% the symbols returned by this parameter would have gone down less than the $SPX.

As you are looking for the 10 day threshold, you would change the 20 to 10.

I'd also suggest changing the > 0 to be a much higher level as a securitiy that went down 4.999 percent vs the $SPX down 5.0% has a PctRelative > 0

Below is a possible sample to "combine" both requirements into a single scan. You have a Part 1 to find the FALLS part and a Part 2 to find the FALLS LESS part.


//FALLS LESS Scan or Alert

//Part 1 FALLS
//Remove the // from in front of the 2 lines after Begin Part 1 to run the FALLS part of the scan

// Begin Part 1 FALLS
[symbol = '$SPX']
and [ROC(10) <= -5.0]
// End Part 1 FALLS


//Part 2 FALLS LESS
// Add // in front of the Part 1 FALLS lines. Remove the // from in front of the 2 lines after Begin Part 2 to run the FALLS LESS part of the scan

// Begin Part 2 FALLS LESS
//[[group is NASDAQ100] or [group is SP500]]
//and [PctRelative(10,$spx) > 3]
// End Part 2 FALLS LESS

//Optional Rank By to put results in PctRelative order
rank by [PctRelative(10,$spx)]
