How to calculate RSI2 at a price

  I’m trying to calculate what the value of RSI[2] would be if on the next bar price had dropped to a certain value.

  I’ve tried several ideas but nothing seems to return the correct values. Anyone know how to do this?

  You can try to reverse engineer the RSI or start from this version: RSI Reverse Engineering indicator

  I’ve reverse engineered the reverse engineered RSI indicator!… and I think I have something that works. In this code the value for RSI2 is returned if price is at the Average[2](Low).

  My plan was to have RSI2 based position sizing and buy on a pending order if price fell to the Average[2](low) so hopefully this can now be done. I’m sure there is most likely a more elegant solution to find this info but I’ll use this until someone else can tell me what that solution is.

  RSIPeriod = 2 for i = 0 to 10000 RSIRevValue = i/100 REM Original RSI values RSIOri = RSI[RSIPeriod](close) UPOri = MAX(0, close - open) //higher close then previous DOWNOri = MAX(0, open - close) //lower close then previous upMAOri = wilderAverage[RSIPeriod](UPOri) downMAOri = wilderAverage[RSIPeriod](DOWNOri) REM Reversed Engineered RSI Value to Price RSRev = (100/((-1*RSIRevValue)+100))-1 if RSIRevValue < RSIOri THEN upMARev = upMAOri*(1-(1/RSIPeriod)) downMARev = upMARev/RSRev DOWNRev = (downMARev - (downMAOri * (1-(1/RSIPeriod))))/(1/RSIPeriod) RSIPriceRev = close - DOWNRev elsif RSIRevValue > RSIOri THEN downMARev = downMAOri*(1-(1/RSIPeriod)) upMARev = downMARev*RSRev UPRev = (upMARev - (upMAOri * (1-(1/RSIPeriod))))/(1/RSIPeriod) RSIPriceRev = close + UPRev endif if RSIPriceRev >= average[2](low) then myRSI = RSIRevValue break endif next //Dummy Trade if average[2] = -1 then buy at market endif graph myRSI

  1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40

  RSIPeriod = 2   for i = 0 to 10000 RSIRevValue = i/100   REM Original RSI values RSIOri = RSI[RSIPeriod](close) UPOri = MAX(0, close - open) //higher close then previous DOWNOri = MAX(0, open - close) //lower close then previous upMAOri = wilderAverage[RSIPeriod](UPOri) downMAOri = wilderAverage[RSIPeriod](DOWNOri) REM Reversed Engineered RSI Value to Price RSRev = (100/((-1*RSIRevValue)+100))-1 if RSIRevValue < RSIOri THEN upMARev = upMAOri*(1-(1/RSIPeriod)) downMARev = upMARev/RSRev DOWNRev = (downMARev - (downMAOri * (1-(1/RSIPeriod))))/(1/RSIPeriod) RSIPriceRev = close - DOWNRev elsif RSIRevValue > RSIOri THEN downMARev = downMAOri*(1-(1/RSIPeriod)) upMARev = downMARev*RSRev UPRev = (upMARev - (upMAOri * (1-(1/RSIPeriod))))/(1/RSIPeriod) RSIPriceRev = close + UPRev endif   if RSIPriceRev >= average[2](low) then myRSI = RSIRevValue break endif next   //Dummy Trade if average[2] = -1 then buy at market endif   graph myRSI
