Why has my position been closed unexpectedly?

A Stop or Limit that you have set on your position has been reached and executed. Your position has been closed due to a margin call. If your "Trade Funds Available" figure has slipped into the negative, add funds to your account or close your current position. Doing nothing will result in the Risk Department closing (or partially closing) your position. Alternatively, you may have been trading on a futures contract and its expiration date has been reached. You may call us before the contract's expiration to roll the contract over to the next expiration date.
