Settlement date

The date in the month when a futures contract expires. This is not always the end of the month and will depend on the broker or the exchange on which the contract is listed.


When you go short on a market, you are hoping to make money if the price falls. One of the advantages of derivatives trading is the ability to short falling markets.

Trailing stop loss

A stop loss that stays the same distance behind a trade as it goes up in price, but stops if it comes down.
