Derivative Oscillator – DEROSC

Derivative Oscillator – DEROSC

The Derivative Oscillator is an advanced version of the Relative Strength Index(RSI) and applies the MACD Histogram principle to the double smoothed RSI. The indicator was developed by Constance Brown and published in her book “Technical Analysis for the Trading Professional.”

The indicator is a twice exponentially smoothed RSI with the default parameters of 5 and 3.
Then a signal line is formed by simple smoothing of the resulting 2ERSI with the period of 9.
The derived histogram is calculated as a difference between 2ERSI and the signal line.

    Many Many Thanks, Nicolas. My broker has a very old version of PRT. So, it give me error at the first line [“BufferRSI = RSI[InpPeriodRSI](InpAppliedPrice)”]. Please, what you suggest me?

      Download the file and import it instead of copy/paste the code.

      the old version I have does not allow importing. It is very old, I think the version 2 of PRT.

    Hi Nicolas,

    I have been extensively researching for lot of answers here. I found that you have been great contributor and helped with solving a lot of issues.
    Thank you for helping.

    I have a question on this indicator. I have imported the indicator. I tried applying to the chart, but I can’t see on the chart.

    Can you help me on this?

      Don’t apply it on price, use the main “indicator and trading system” button found on the top bar of each price chart.
