I found the answer:
You can use “*” as a parameter in rawFields() or formattedFields() in Quotes plug-in object.
var quote = JET.Quotes.create()
.rics("GOOG.O")
.rawFields("*")
.onUpdate(function (subscription, ric, updatedValues) {
console.log(subscription.getFieldsValues(ric)); })
.start();
Just a thought: do you really need all fields ? The more fields you subscribe to, the heavier the load on the app and machine running it.
