Re: How to apply functions to other than tickers?

["nenapacwanfr" <nenapacwanfr@xxxx>]

not easy, because ADX uses DM ( dir movement ) that use High, low
OBV has one fixed value.
Stephane
for example the code of ADX is below


Periods= Optimize("Enter time periods",7,7,40,1);

PlusDM= IIf(High>Ref(High,-1) AND
Low>=Ref(Low,-1), High-Ref(High,-1),
IIf(High>Ref(High,-1) AND Low<Ref(Low,-1)
AND High-Ref(High,-1)>Ref(Low,-1)-Low,
High-Ref(High,-1),0));
DIPlus= 100 * Wilders(PlusDM,Periods) /
ATR(Periods);

MinusDM= IIf(Low<Ref(Low,-1) AND
High<=Ref(High,-1), Ref(Low,-1)-Low,
IIf(High>Ref(High,-1) AND Low<Ref(Low,-1)
AND High-Ref(High,-1)<Ref(Low,-1)-Low,
Ref(Low,-1)-Low, 0));
DIMinus= 100 * Wilders(MinusDM,Periods) /
ATR(Periods);

DIDif= abs(DIPlus - DIMinus);
DISum= DIPlus + DIMinus;
ADXRaw= 100 * Wilders(DIDif/DISum, Periods);

Plot(ADXRaw,"",2,1);
