How to translate the metastock code to prorealcode (indicator RS EMA)?

  Hi,

  From the article “Relative Strength Moving Averages ” in the latest issue of Stocks & Commodities Jan 2022 there is an interessting indicator called RS EMA. But it is written in METASTOCK code and look as follow:

  Periods:=50; Pds:=50; Mltp:=10; Mltp1:=2/(Periods+1); Cup:=If(C>Ref(C,-1),C-Ref(C,-1),0); Cdwn:=If(C<Ref(C,-1),Ref(C,-1)-C,0); RS:=Abs(Mov(CUP,Pds,E)-Mov(Cdwn,Pds,E))/(Mov(CUP,Pds,E)+Mov(Cdwn,Pds,E)+0.00001); RS:=RS*Mltp; Rate:=Mltp1*(1+RS); If(Cum(1)=Periods+1,C,PREV+Rate*(C-PREV));

  1 2 3 4 5 6 7 8 9 10 11

  Periods:=50; Pds:=50; Mltp:=10; Mltp1:=2/(Periods+1); Cup:=If(C>Ref(C,-1),C-Ref(C,-1),0); Cdwn:=If(C<Ref(C,-1),Ref(C,-1)-C,0); RS:=Abs(Mov(CUP,Pds,E)-Mov(Cdwn,Pds,E))/(Mov(CUP,Pds,E)+Mov(Cdwn,Pds,E)+0.00001); RS:=RS*Mltp; Rate:=Mltp1*(1+RS);   If(Cum(1)=Periods+1,C,PREV+Rate*(C-PREV));

  It said this in RS EMA has less lags than the normal EMA (see attached png).

  I have problem to translate the last line (line 11) to prorealcode. It seems a recusive. Can someone help?

  Here is my code:

  // From S&C Jan. 2022 "Relative Strength Moving Averages" - Vitali Apirine Periods = 50 Pds = 50 Mltp = 10 Mltp1 = 2/(Periods+1) if close >close[1] then Cup = close - close[1] else Cup = 0 endif if close < close[1] then Cdwn = close[1] - close else Cdwn = 0 endif EMAup = ExponentialAverage[Pds](Cup) EMAdwn = ExponentialAverage[Pds](Cdwn) RS1 = abs((EMAup - EMAdwn)/(EMAup + EMAdwn + 0.00001)) RS = RS1 * Mltp Rate = Mltp1 * (1 + RS) RETURN ???

  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

  // From S&C Jan. 2022 "Relative Strength Moving Averages" - Vitali Apirine   Periods = 50 Pds = 50 Mltp = 10   Mltp1 = 2/(Periods+1)   if close >close[1] then Cup = close - close[1] else Cup = 0 endif   if close < close[1] then Cdwn = close[1] - close else Cdwn = 0 endif   EMAup = ExponentialAverage[Pds](Cup) EMAdwn = ExponentialAverage[Pds](Cdwn)   RS1 = abs((EMAup - EMAdwn)/(EMAup + EMAdwn + 0.00001)) RS = RS1 * Mltp   Rate = Mltp1 * (1 + RS)   RETURN ???

  This should be complete:

  // From S&C Jan. 2022 "Relative Strength Moving Averages" - Vitali Apirine Periods = 50 Pds = 50 Mltp = 10 Mltp1 = 2/(Periods+1) if close >close[1] then Cup = close - close[1] else Cup = 0 endif if close < close[1] then Cdwn = close[1] - close else Cdwn = 0 endif EMAup = ExponentialAverage[Pds](Cup) EMAdwn = ExponentialAverage[Pds](Cdwn) RS1 = abs((EMAup - EMAdwn)/(EMAup + EMAdwn + 0.00001)) RS = RS1 * Mltp Rate = Mltp1 * (1 + RS) IF BarIndex <= (Periods + 1) THEN ReturnedDatum = close ELSE ReturnedDatum = ReturnedDatum[1] + Rate * (close - ReturnedDatum[1]) ENDIF RETURN ReturnDatum AS "RS Moving Average"

  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

  // From S&C Jan. 2022 "Relative Strength Moving Averages" - Vitali Apirine Periods = 50 Pds = 50 Mltp = 10 Mltp1 = 2/(Periods+1) if close >close[1] then    Cup = close - close[1] else    Cup = 0 endif if close < close[1] then    Cdwn = close[1] - close else    Cdwn = 0 endif EMAup  = ExponentialAverage[Pds](Cup) EMAdwn = ExponentialAverage[Pds](Cdwn) RS1 = abs((EMAup - EMAdwn)/(EMAup + EMAdwn + 0.00001)) RS = RS1 * Mltp Rate = Mltp1 * (1 + RS) IF BarIndex <= (Periods + 1) THEN    ReturnedDatum = close ELSE    ReturnedDatum = ReturnedDatum[1] + Rate * (close - ReturnedDatum[1]) ENDIF RETURN ReturnDatum AS "RS Moving Average"

  It was written incorrectly, this is the correct line:

  RETURN ReturnedDatum AS “RS Moving Average”

  1	RETURN ReturnedDatum AS “RS Moving Average”
