RE: [amibroker] RSI plots don't match

["Graham" <gkavanagh@xxxxxxxxxxxxx>]

Yes I had the same, and found an AFL by DT that made them match
PerRSI = 14;
MUp=IIf(C>Ref(C,-1),abs(C-Ref(C,-1)),0);
MDn=IIf(C<Ref(C,-1),abs(C-Ref(C,-1)),0);
Rup = Wilders(Mup,PerRSI);
Rdn = Wilders(Mdn,PerRSI);
myRSI =  100*(Rup / (Rdn+Rup) ) ;

Cheers,
Graham

Subject: [amibroker] RSI plots don't match


I have a trading program that plots an RSI with the following 
formula in Metastock format:

rsi_r := (close - open); 
rsi_rs := Wilders(if(rsi_r>0,rsi_r,0),period) / Wilders(if
(rsi_r<0,Abs(rsi_r),0),period); 
RSI := 100-(100/(1+rsi_rs));

The problem is that I get different results when compared to AB's 
RSI (I don't know AB's RSI formula).  How can I adapt the one above 
to match that of AB?

TIA

Gernot
