AMO Vs Simple Orders


When we compare AMOs and Simple orders and which one is better?, It is always better to place a normal order at market opening to get faster execution. In case of AMOs, all orders are accumulated and then sent as a bulk order on market opening. This bulk order request goes in a queue and takes time to execute.
