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

[pumrysh <no_reply@xxxxxxxxxxxxxxx>]

Roy,

Thanks for the input.

Crom,

The capabilities exist but do require work on your part and as Roy pointed out, the potential for garbage if you don't set it up correctly is high.

Let me also point out that Roy has a great talent for utilizing the Metastock utilities in ways that the developers never dreamed of. If you really want to see Metastock on steroids you should check out his work.

Another way to solve your problem might be to simply write a custom indicator for your application where the input values are set...like this:

{My Custom Indicator}
UserData:=5;
{remaining indicator code}

rather than using 

{My Indicator}
UserData:=Input("User Input",0,99,5);
{remaining indicator code}
  

The final method that you choose to solve your problem is your decision. Just take your time and think through the process and I'm sure you will do just fine.

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.
