What is a tick? I am very confused by it. Is it the trade price that most recently closed? As and when a trade is completed a tick is generated and calls ExUpdate() for the request below?
TickSource = ExtSubscribe(1, nil, "t1", instance.parameters.Type == "Bid", "close");
TickSource = ExtSubscribe(1, nil, "t1", instance.parameters.Type == "Bid", "close");
