Investor Preference Index was discussed in the “Technical Analysis of Stocks & Commodities” magazine in December, 1997, page 19. The article was written by Cyril V. Smith Jr.
Initially, this indicator, which was used as the long-term stock market investment tool, compared the efficiency of S&P 500 with the New York Stock Exchange to measure sentiment. The theory suggests that investors prefer certain types of investment.
The indicator has five input parameters:
- Instrument – the name of the financial instrument
- ROC period – period for calculating the price rate of change
- Fast smoothing period – the period of the fast smoothing
- Slow smoothing period – the period of the slow smoothing
- Result smoothing period – the period of the resulting smoothing
Calculation:
IPI =100.0*(Result smoothing period * SMA(B2, Result smoothing period)+1.0)
where:
B2 = SMA(B1,Β Fast smoothing period) - SMA(B1,Β Slow smoothing period) B1 = ROC1 - ROC2
ROC1 - the current symbol's price rate of change over the ROC period ROC2 - the 'Instrument' symbol's price rate of change over the ROC period
ROC = 100.0 * Log(Close - Log2) / Log2
Log2 = Log(Close[ROC period])
Please note that in order for the indicator to display correctly, historical data for the ‘Instrument’ symbol are needed, which can lead to a delay in displaying the oscillator line during the first launch or symbol changed.
