The Cantor Exchange market is constantly being updated as contract prices are changing. Therefore, when you submit an order request, the market may move away from your requested trade price before your order actually reaches the server.


Your order is more likely to be filled when submitting a GTC or Good Til Cancel Limit Order. When submitting a GTC order, your order will sit on the order book until one of the following events occurs: the order is filled; the order is cancelled; the contract reaches the expiry time. The default order type on the Tradologic trading interface is GTC.


When submitting an IOC or Immediate or Cancel Limit Order, if there is no matching order on the order book when your order request is received, the order is cancelled right away and is not left sitting on the order book. If the market happens to move away from your trade price before your request reaches the server, your IOC order will not be filled and, therefore, will be cancelled.


If you look at your Order History report, you can view the history of all of your orders, filled or unfilled.

If your order failed to submit, you will see “Syscxled” in the Status column for the given order. This is a system cancelled notice. If you click on the given order number, it will open up a drill down of the order, including details as to why you have received the system cancelled notice under the Reason column.

The most common system cancelled notice is ‘No opposing order in book.’ The ‘No opposing order in book’ notice occurs when you request to purchase a position at a certain price and the automated liquidity providers in the market move away from that price before your request reaches the server and, therefore, your order does not get filled.
