Market volatility and rapid changes in price, which may arise outside normal business hours if you are trading international markets, can cause the balance of your account to change quickly. If you do not have sufficient funds in your account to cover these situations, there is a risk that your positions will be automatically closed by the platform if the balance of your account falls below the close-out level (as shown on the platform).
You should continuously monitor your account and deposit additional funds or close your positions (or a portion of your positions) so that the funds in your account cover the total margin requirement at all times. The information icon within the main account bar at the top of the CFD trading platform will detail all your account information, including the close-out percentage level.
Account close-out example:
If the current close-out percentage level is 50% and you have four trades open that each require $500 worth of position margin, your total position margin requirement will be $2000. If your account revaluation amount then drops to less than 50% of the total margin requirement, in this case $1000, some or all of the trades constituting this position may be closed out, potentially at a loss to you.
The account revaluation amount is the sum of your cash and any net unrealised profit or loss (as applicable), where net unrealised profit or loss is calculated using the level 1 mid-price.
