kennerhk,

The error message refers to your input statement which should be in the format

INPUT(MESSAGE[,DEFAULT,MINIMUM,MAXIMUM]).

If you cut and paste your code into BS, perform 'check' then you get the error message that you found. However you also get the option for BS to correct the code. Select 'yes' and then hey presto your input line will change to

periods:=input("TMF periods", 21, 1, 100);

and your code will now work.

regards,

p.s. You also have to remove the space in "p eriods" in the last line.

I am trying to build an indicator in BC, but know ZERO about this, so I'm hoping someone can help me out. This indicator is a variation on the Chaikin MoneyFlow with some exponential smoothing built in to correct some false signals. The Metastock code provided by the indicator's author/creator on his website is as follows:

{2003-09-24}

periods:=Input("TMF periods",1,100,21);

TRH:=Max(Ref(C,-1),H);

TRL:=Min(Ref(C,-1),L);

TR:=TRH-TRL;

ADV:=((C-TRL)-(TRH-C))/If(TR=0,999999,TR)*V;

WV:=V+(Ref(V,-1)*0);

If(Wilders(WV,periods)=0,0,Wilders(ADV,periods)/Wilders(WV,p eriods))

I tried to just cut and paste this into the indicator builder window, but when I try to do that, I get the following error message:

"Error 902: parameter 3 to input function must not be greater than parameter 2"

Does anyone know how to tweak this to run in BC? Ideally, I'd like the correct code so I can just cut and paste it into the Indicator Builder. Would greatly appreciate your help on this.

Thanks in advance!
