If Done versus OCO Orders http://www.financial-spread-betting.com/Stop-loss.html 'If Done' (contingent) Orders. Some spread betting brokers also allow contingent orders. As the name suggests, these orders only happen if some other condition is satisfied. One example of this would be if you placed a limit order to enter a trade at a certain level. You could also place a contingent order to set a stop loss, contingent on the trade having been opened - after all, you do not want to "sell to close" a position if the trade has not been opened yet.
