Re: [amibroker] Filter and Parameter

[ChrisB <kris45mar@xxxxxxxxxxxx>]

Hi

I am still thinking about this:

I want to use the Param function in Exploration to control one of three 
values I want to use for the Filter:

Paramtoggle only gives me two values, to pass into the Filter: true or 
false, so I cannot use this.

If I run
UPbar = C > O; Downbar = C < O;

Filter =1; // in Exploration this works
Filter = UPbar; // In exploration this works
Filter = Downbar;// in exploration this works

So I have looked at ParamList:

This code does not do what I would have thought:

Typebar = paramlist("Typeofbars", "upbar, Downbar, AllBars",2);
TB = iif(Typebar == "Upbar", Upbar,
iif(Typebar == "downbar",Downbar,
iif(typebar == "AllBars, 1, Null)));
filter = tb;

Exploration runs, but I get columns with heading with no data.

Still not sure where to go from here.

Any nudges in the right direction would be appreciated.

thanks

ChrisB
