I am looking for an indicator pcf that implements the VolatilitySwitch indicator by Ron McEwan.

Thanks,

Dana

If you are OK with the indicator running from 0 to 100 instead of 0 to 1, you can use the following Formula in a Custom PCF Indicator in TC2000 v17.

SQR((SUM(((C - C1) / ((C + C1) / 2)) ^ 2, 21) - SUM(((C - C1) / ((C + C1) / 2)), 21) ^ 2 / 21) / 21)

And add a Worden Stochastic indicator with a Period of 21 and %K of 1 to the same chart with the Data Source set to use the Custom PCF Indicator you created earlier as the Data Source of the Worden Stochastic. You will probably also want to remove the %D indicator from the chart.

Add and edit indicators on your chart - (1:49)
Change an indicator's data source - (2:02)

You would have to change both the period of the Worden Stochastic and all instances of 21 in the Formula in the Custom PCF Indicator to change the period of the Volatility Switch indicator.

Thanks. I don't care about the range, so this should work well.

BTW, it looks like for this to work you have to take %K down to 1. That seems to estimate the indicator pretty well.

Yes, you definitely have to take the %K to 1. Sorry I didn't mention that. You probably also want to remove the %D indicator.

How come the "create a condition" window that opens changes when you change the

data source?

 

It doesnt look like you can create a scan?

 

 

 

 

Thanks

Click on the formula label, then Create Scan Condition.

You should see your formula listed with Worden Stochastics below it. Select Worden Stochastics from the Indicator dropdown and you should be able to create the condition. 

I'm not sure why it does not work when you start by clicking on Worden Stochastics.

That seems to open a window to edit Worden Stochastics

not create a condition.

Thanks
