The ‘force open’ function on the trading platform allows you to enter a new deal in the opposite direction to an existing deal on the same market.
This will ensure that you have two distinct positions open. If you do not check ‘force open’ in this situation and instead have 'net off' selected, all or some of your existing position may be closed.
When using IG’s desktop platform, the ability to ‘force open’ is listed underneath the 'deal' and 'order' selection box. If left unchecked, and instead 'net off' is selected, then our platform will close any existing positions that would be cancelled out by the new position. If you buy 100 shares of Exxon Mobile when you have an open position to sell 100 shares of Exxon Mobile, for instance, IG would simply close the open position in this scenario.
If the ‘force open’ box is checked, our platform will not do this and the position will be opened as a standalone, new trade. In this respect, a forced open is a different matter to a forced close, which occurs when a position is closed automatically without any action by a trader.
