Re: [EquisMetaStock Group] Re: Using explorer to send parameters to formulae

["Roy Larsen" <rlarsen@xxxxxxxxxx>]

Hi Crom/Preston

 

 

It's possible using Mark Pyle's GV DLL to pass parameters on to other tools. There are conditions, of course, such as the indicator must have been pulled down onto a chart to allow the user-input to be read and saved as a global variable. Here's how I recall making it work when I last tested the method.

 

{My Indicator}

UserData:=Input("User Input",0,99,5);

UserData:=ExtFml("GV.SetVar","UserData",UserData);

{remaining indicator code}

 

 

{My Exploration}

 

{colA}

UserData:=LastValue(ExtFml("GV.GetVar","UserData"));

{remaining exploration code}

 

I don't have any full working examples of code but I do know that the process works as long as the global variable(s) is/are set up in each MetaStock session before the exploration attempts to use them. If not set up correctly your results will be garbage.

 

 

Regards

 

Roy

Thanks for that Preston. So, does that mean that I am correct in that there
is no way to send formula parameters to the formulae themselves, from the
explorer, when running explorations?

Cheers,
Crom

Crom,

Just remember that the default inputs will be used when you call the
formulas.
