Bruce,

In earlier topics you give information for a volitility stop indicator. You give the formula July 13 2009. However I have tried to drop the formula following the inherits line and errors appear.  Would you please give me the formula where it can be placed immediately below the "inherits" line in the Class Tab.

Thanks,

Ed

If you are talking about my Monday, July 13, 2009 12:55:03 PM ET post in the My volatility stop in SF topic, it is designed to be pasted into the Code tab of a RealCode Indicator and not into the Class tab below the Inherits line.

Also note that first line would need to be replaced as it is an example of applying the Volatility Stop to another indicator instead of applying it to price.


'# MI = indicator.MyIndicator

You would drag and drop the indicator into the RealCode Editor and then set the variable name to MI instead of whatever gets assigned so the rest of the RealCode can access it.

If you want RealCode for a Volatility Stop calculated on price, I'd probably just use the RealCode from the first post in the topic in the Code tab.

Bruce,

Thanks.. Is Period the look back period in time segments as given on the Chart, and the Factor the multiples of ATR?

Thanks, Ed

Factor is the multiple of ATR.

Period is very similar to the looback in time segments, but it is using Wilder's Smoothing instead of something like a simple moving average, so a period of 14 doesn't mean it is looking at 14 bars. The idea of increasing the period to increase the lookback is quite similar however.

Bruce,

Thanks for the information.  The indicator works great, and behaves similar to Wilder's PSAR.

Thanks, Ed
