Trading foreign exchange on margin carries a high level of risk, and may not be suitable for all investors. Before deciding to trade foreign exchange you should carefully consider your investment objectives, level of experience, and risk appetite. You could sustain a loss of some or all of your initial investment and should not invest money that you cannot afford to lose. CFDs are complex instruments and come with a high risk of losing money rapidly due to leverage.

Force open definition

What is force open?

Force open is a function on the trading platform that allows you to enter a new bet in the opposite direction to an existing bet on the same market. This will ensure you have two distinct positions open, except in the case where you have a short position on an unborrowable share.

A forced open should not be confused with a forced close, which occurs when a position is closed automatically without any action by you.

Force open vs net off

If you opt not to use force open, your open positions may be ‘netted off’. This is when existing positions are automatically closed if they would be cancelled out by the new position (unless you attach a stop or a limit, in which case it will keep both positions open).

Force open on IG’s platform

On IG’s desktop, the ‘force open’ option is listed underneath the size field – if you do not check 'force open' all or some of your open positions may be automatically netted off.

Force open on unborrowable stock

If you use force open when shorting unborrowable stock, the two positions will not be treated as 'distinct', as you will not be able to close the long position unless you close the short position first. Closing the long position ahead of the short will be treated in the same way as opening a new short position, which you cannot do on an unborrowable equity.
