RE: [amibroker] ADX

<SPAN

here 
is a formula for ADX. Since the indicator looks at high and low values of the 
security you could rename the Highs and Lows with a custom "Line" I do not know 
what you are trying to accomplish but something along the lines 
of.....
<SPAN 
class=136234714-26022003> 
<SPAN 
class=136234714-26022003>h=ma(h,50); 
<SPAN 
class=136234714-26022003>l=ma(l,50);
<SPAN 
class=136234714-26022003> 
Since 
the built in indicator is probably using the built in PDI and MDI for the math 
you would probably need to convert the code below to AB then plot 
"ADXFinal"

ADX Custom
Periods:=Input("Time 
Periods",1,100,14);PlusDM:=If(H>Ref(H,-1) AND L>=Ref(L,-1), 
H-Ref(H,-1),If(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:=If(L<Ref(L,-1) 
AND H<=Ref(H,-1), Ref(L,-1)-L,If(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);ADXFinal
