Keith,
Here are two formulas: ADXR Custom and ADX custom, Is this what you
seek.
/* ADXR CUSTOM */
Periods=14;
PlusDM=IIf(H>Ref(H,-1) AND L<=Ref(L,-1), H-Ref(H,-1),IIf(H>Ref(H,-1) AND
L<Ref(L,-1)
AND H-Ref(H,-1)>Ref(L,-1)-L,
H-Ref(H,-1),0));
PlusDI=100*Wilders(PlusDM,Periods)/ATR(Periods);
MinusDM=IIf(L<Ref(L,-1) AND H<=Ref(H,-1), Ref(L,-1)-L,IIf(H>Ref(H,-1)
AND L<Ref(L,-1)
AND H-Ref(H,-1)<Ref(L,-1)-L,
Ref(L,-1)-L,0));
MinusDI=100*Wilders(MinusDM,Periods)/ATR(Periods) ;
DIDif=abs(PlusDI-MinusDI);
DISum=PlusDI+MinusDI;
ADXFinal=100*Wilders(DIDif/DISum,Periods);
ADXRCUSTOM= (ADXFinal+Ref(ADXFinal,LastValue(1-periods)))/2;
Graph0=ADXRCustom;
/************************************************************/
/* ADX CUSTOM*/
Periods=14;
PlusDM=IIf(H>Ref(H,-1) AND L>=Ref(L,-1), H-Ref(H,-1),IIf(H >Ref(H,-1)
AND L<Ref(L,-1)
AND H-Ref(H,-1)> Ref(L,-1)-L,
H-Ref(H,-1),0));
PlusDI=100*Wilders(PlusDM,Periods)/ATR(Periods);
MinusDM=IIf(L<Ref(L,-1) AND H<=Ref(H,-1), Ref(L,-1)-L,IIf(H>Ref(H,-1)
AND L<Ref(L,-1)
AND H-Ref(H,-1)<Ref(L,-1)-L,
Ref(L,-1)-L,0));
MinusDI=100*Wilders(MinusDM,Periods)/ATR(Periods) ;
DIDif=abs(PlusDI-MinusDI);
DISum=PlusDI+MinusDI;
ADXFinal=100*Wilders(DIDif/DISum,Periods);
Graph1=ADXFinal;
Title=Name()+" ADXR RATING: "+"("
+WriteVal(ADXRCUSTOM,FORMAT=1.2)+")"+" :::" +" ADX VALUE
"+"("+WriteVal(ADXFINAL,FORMAT=1.2)+") ";
