Instruments that are based on a futures contract either have an expiry date or a rollover date. You can find out which by clicking on the "Details" link on the main trading platform screen next to the instrument’s name. Whenever a futures contract reaches its expiry date, all open positions and Orders for that instrument are terminated, regardless of any associated Orders you may have set beforehand.
For more information on rollover dates, please read “Do you offer a Rollover service?”
