StochRSI - PCF's NeuroCat(ejr39) Recently, I began reading SI's TA - Beginner's thread and realized that most of the DNS could be programmed in TC2000 version 4; so now, for Chande's Stochastic RSI: StochRSI = (RSI - RSIL)/(RSIH -RSIL) where RSIL and RSIH are the lowest and highest values of the RSI over a given period. In his book he uses 14 periods. In TC2000, the translation for StocRSI is: ((RSI14 - MIN(RSI14,14)) / ((MAX(RSI14,14) - MIN(RSI14,14))+.001) * 100) As you know, Catlady, TC2000 doesn't have charting capabilities for the StocRSI; the StochRSI > 30 is simple: ((RSI14 - MIN(RSI14,14)) / ((MAX(RSI14,14) - MIN(RSI14,14))+.001) * 100) > 30 But how is the direction of the indicator determined (using only TC2000) - would ((RSI14 - MIN(RSI14,8)) / ((MAX(RSI14,8) - MIN(RSI14,8))+.001) * 100) > ((RSI14 - MIN(RSI14,14)) / ((MAX(RSI14,14) - MIN(RSI14,14))+.001) * 100) work? StoRSI increasing(NeuroCat01) Try this for StochRSI today - StochRSI 2 days ago > 0 (((RSI14 - MIN(RSI14,14)) / ((MAX(RSI14,14) - MIN(RSI14,14))+.001) * 100) ) - (((RSI14.2 - MIN(RSI14.2,14)) / ((MAX(RSI14.2,14) - MIN(RSI14.2,14))+.001) * 100)) > 0 Using 2 days difference instead of 1 was a totaly arbitrary decision on my part. I charted the same StoRSI indicators in Metastock and the charts look OK to me. StoRSI today (RSI(14)-LLV(RSI(14),14))/((HHV(RSI(14),14)-(LLV(RSI(14),14)))+.001)*100 StoRSI 2 days ago (Ref(RSI(14),-2)-LLV(Ref(RSI(14),-2),14))/((HHV(Ref(RSI(14),-2),14)-(LLV(Ref(RSI(14),-2),14)))+.001)*100 Also, your StoRSI formula agrees with Chande's but the folks on SI seem to be using a version with an extra Moving Average thrown in for smothing, like this: Mov((RSI(14)- LLV(RSI(14),14)) /((HHV(RSI(14),14)-(LLV(RSI(14),14))),14,E)+.001)*100 Now, that would be hardier in TC2K, do we need it?

"As an RSI user, you may have been frustrated when the RSI did not reach an extreme value (above 80 or below 20) for months at a time. Perhaps you wanted an entry point into an ongoing trend, and were looking for a price extreme, but couldn't find one using RSI. The solution to your problem is the Stochastic RSI (StochRSI)." "The StochRSI combines the two popular ideas behind the RSI and the Stochastic oscillator. The Stochastic oscillator measures the location of closing prices within the recent high to low range. Similarly, StochRSI measures the location of RSI within its recent range, showing short-term momentum extremes. It can be used as an antitrend or a trend-following tool." "The sensitivity of the StochRSI overcomes the disadvantages of using a fixed number of days in its calculation and the tendency of the built-in RSI smoothing to mask short-lived price extremes while showing swing failures in RSI. The ability to spot short-term extremes in RSI (and momentum) is its principal advantage. The StochRSI is a more consistent indicator of overbought and oversold conditions simply because we are measuring its position within the most recent range." The above explanation of StochRSI was taken from "The New Technical Trader" by Tushar S. Chande and Stanley Kroll For the entire message, http://www.techstocks.com/~wsapi/investor/reply-540925 |
