I am trying to find some information on the technical indicator SIROC (Smoothed Indexed Rate of Change). Could you point me towards something please?
In answering your question, I sought the assistance of Sharefinder. I acknowledge the assistance of Greg Campbell and Gary Stone, from whose replies I have made up the following:
The SIROC indicator is a proprietary indicator. Its formula is not in the public domain. SIROC stands for Smoothed Indexed Rate of Change. It forms part of the Sustained Profit Advantage Medium Term Trading Systemä.
The smoothing is not described and the algorithm is the real secret to this indicator. The only clue is that its smoothing characteristics are similar to MACD. The indexing simply forces its values to lie within the range 0 to 100, in a similar way to RSI and Stochastics and unlike MACD, which has no fixed boundaries to the oscillator.
There are two parameters for SIROC. The first defines the period of the rate of change. The second defines the amount of smoothing. More information is available from Sharefinder (http://www.sharefinder.com.au ).
