Re: [EquisMetaStock Group] Change the setting of function

["formulaprimer" <formulaprimer@xxxxxxxxx>]

You just change the default functions by making your own custom formula for the indicator or changing the default setting if it will allow you. example for OBTR Rapid your can change the default settings
FmlVar("On Balance True Range MACD Hist","SIGNALMA") another example is bollinger bands BBandTop(DA, Prds, E S T TRI VAR W, Deviations)

TrueRangeHigh:=Max( Ref(CLOSE,-1), HIGH );
TrueRangeLow:=Min( Ref(CLOSE,-1), LOW );
OBTR:=Cum(If(C > Ref(C,-1),C-TrueRangeLow, If(C < Ref(C,-1),C-TrueRangeHigh,0)));

ShortMA:= Input("ShortMA -",1,200,8);
LongMA:= Input("LongMA -",1,200,17);
SignalMA:= Input("SignalMA - ",1,200,9);
MACDOBTR:=Mov(OBTR,ShortMA,E) - Mov(OBTR,LongMA,E);
If(MACDOBTR>=Ref(MACDOBTR,-1),MACDOBTR,0);
If(MACDOBTR<Ref(MACDOBTR,-1),MACDOBTR,0);
Mov(Mov(MACDOBTR,ShortMA,E)-Mov(MACDOBTR,LongMA,E), SignalMA,E);
