SyntaxError: missing ; before statement (??)...

[asherisaac]

this code serves no purpose yet, but i can't figure out why i'm getting the error...



preMain() {

setStudyTitle("AID_PAIR_TRADER");
setCursorLabelName("AID_PAIR_TRADER");

}



main(s1, s2) {
var BOLLY = new BollingerStudy(20, "Close", 2);
var UPPER = BOLLY.getValue(BollingerStudy.UPPER);
var LOWER = BOLLY.getValue(BollingerStudy.LOWER);
var BASIS = BOLLY.getValue(BollingerStudy.BASIS);

if ((UPPER == null) || (LOWER == null) || (BASIS == null)) {

return; }


if (s1 == null) {

s1 = "SPY";

}

if (s2 == null) {

s2 = "QQQ";

}





return;

}

You are missing the word function before preMain() and main(s1,s2).
Alex

function preMain() {  

setStudyTitle("AID_PAIR_TRADER");
setCursorLabelName("AID_PAIR_TRADER");

}



function main(s1, s2) {
var BOLLY = new BollingerStudy(20, "Close", 2); 
var UPPER = BOLLY.getValue(BollingerStudy.UPPER);
var LOWER = BOLLY.getValue(BollingerStudy.LOWER);
var BASIS = BOLLY.getValue(BollingerStudy.BASIS);

if  ((UPPER == null) || (LOWER == null) || (BASIS == null)) {

            return; }


if (s1 == null) {

     s1 = "SPY";
     
     }

if (s2 == null) {

     s2 = "QQQ";
     
     }
   




return;

}

Hello asherisaac,

I'd also recommend moving your code for initializing the Bollinger study outside of main. You only need to establish a study object once. Your formula will still work if you leave it inside main. However, it's a less efficient process.

var BOLLY = new BollingerStudy(20, "Close", 2); 

function main(s1, s2) {
var UPPER = BOLLY.getValue(BollingerStudy.UPPER);
var LOWER = BOLLY.getValue(BollingerStudy.LOWER);
var BASIS = BOLLY.getValue(BollingerStudy.BASIS);

if  ((UPPER == null) || (LOWER == null) || (BASIS == null)) {

            return; }
