Get Value of ParamField()

AFL Programming
1

Is there any way to get the current ParamField() selection in AFL? ParamField() returns the selected array, but I can’t find any way to programmatically determine which array the user has selected. I’m trying to display the selection as part of the chart commentary. I tried using _DEFAULT_NAME(), but that returns a lot of extra info. I guess I could use the string functions to extract it, but I’m wondering if there’s a specific variable for it?

hello
what about _PARAM_VALUES()

Sorry i was wrong for _PARAM_VALUES()

For Interpretation you can use something like

per = Param("rsi period" ,14,5,30);
testRsi= RSI(per);

printf("\n"+
" my Parameters On RSI (" + per+") , and Close is "+ C  );

below one more example with _PARAM_VALUES()

per = Param("rsi period" ,14,5,30);
dummy1 = Param("dummy1 period" ,10,5,30);
dummy3 = Param("dummy3 period" ,50,5,30);

testRsi= RSI(per);

printf("\n"+
" my Parameters On RSI (" + per+") , and Close is "+ C + "\n\nAlso using dummy param() and _PARAM_VALUES(),  are: <b> " + _PARAM_VALUES()+"</b>");

P = ParamField("Price field",-1);

printf("\n"+
" My ParamField is " + _PARAM_VALUES()+ " with value  (" + p+ ")" );

Maybe consider using ParamList and populating the array yourself based on the selection.

Thanks for the suggestion, PanoS. This is what I ended up using:

StrMid(StrExtract(_PARAM_VALUES(), 0), 1)
