The AIQ code based on Vitali Apirine’s article in STOCKS & COMMODITIES, “The Slow Relative Strength Index,” is shown here. This code for the slow RSI (SRSI) is for use as an indicator. A sample chart illustrating the SRSI is shown in Figure 7.
FIGURE 7: AIQ. This example chart shows the slow RSI (6,14) compared to the classic RSI (14).
!THE SLOW RELATIVE STRENGTH INDEX !Author: Vitali Aprine, TASC April 2015 !Coded by: Richard Denning 5/3/2015 !www.TradersEdgeSystems.com !INPUTS FOR INDICATOR: emaLen is 6. wilderLen is 14. !INDICATOR FORMULAS: ema is expavg([close],emaLen). pDif is iff([close] - ema > 0,[close] - ema,0). nDif is iff([close] - ema < 0,ema - [close],0). rsiLen is 2 * wilderLen - 1. AvgU is expavg(pDif,rsiLen). AvgD is expavg(nDif,rsiLen). srsi is 100-(100/(1+(AvgU/AvgD))). !PLOT
