FunctionParameter question

[Patch227]

Hello

I am having difficulty understanding why my FunctionParameters are not coming up in the >Chart Options/Edit studies.

Can someone perhaps explain please?

Thanks

function preMain() {
    setStudyTitle("IB Try");
    setPriceStudy(true);
    setShowCursorLabel(false);

    // default parameters
    var     fp0 = new FunctionParameter("Risk", FunctionParameter.NUMBER);
            fp0.setName("Risk");
            fp0.setDefault(150);


    var     fp1 = new FunctionParameter("PSL", FunctionParameter.NUMBER);
            fp1.setName("PSL");
            fp1.setLowerLimit(1);
            fp1.setDefault(20);



var Long
var PSL
var Size
var Risk
var Bid





}
function main(){
var nState = getBarState();

    Bid =   getMostRecentAsk()  
    
        
            debugPrintln(Bid);

    }

You need to add the FunctionParameter names in the arguments of the main() function eg
function main(Risk, PSL){
For more information and examples on the FunctionParameter Object see this article in the EFS KnowledgeBase and/or any one of the studies included in the EFS2 Custom folder in Formulas

Thank you Alex. Nowhere in the EFS literature have I seen this mentioned.

You are most welcome.
As to this not being mentioned in the EFS literature I am not sure what you mean as it is explained in depth in the Tutorial 3: Introduction to preMain() and main() which is available in the EFS KnowledgeBase in the Help Guides and Tutorials-> Beginner Tutorials and it is mentioned in the examples shown in the article I pointed to in my previous reply and in the EFS Editor Help file (under FunctionParameter Object)
