onOpen -> balance

[krasnopv]

var entries = [{ name : "Update Portfolio", functionName : "balance" }];
Where is this function balance() in js Files? Maybe there should be another function in Menu?

Thanks and updated

function onOpen() {
  var sheet = SpreadsheetApp.getActiveSpreadsheet();
  var entries = [{ name : "Update Portfolio", functionName : "balnew" }];
  sheet.addMenu("Cryptos Tools", entries);
};
