When setting an order, a trader can choose different 'Time in Force' strategies to set the effective execution method of the order. Order execution strategies allow traders to have more control over their trading strategies.

1. Locate the order placement zone on the right side of the trading page.

2. Time-in-force function is only available to limit and conditional limit orders. Click on 'Good-Till-Cancelled' and select your time-in-force order strategy from the pop-up menu.

3. Proceed to successfully place the order. The system will execute the order based on the selected time-in-force order strategy.
