A guaranteed stop-loss order (GSLO), available for most products, works in the same way as a stop-loss order except that it guarantees to close out a trade at the price specified, regardless of market volatility or gapping.
If you wish to place a GSLO on a trade, you will need to pay a small cost, called a 'GSLO premium' in the trading platform.
The GSLO premium calculation when placing a guaranteed stop-loss order on a trade is: premium rate x £/point.
The applicable premium rate can be found on the trading platform, in the product overview for the relevant product.
The premium will be charged when placing the GSLO, including when this is done by changing an existing pending regular stop-loss or trailing stop-loss order to a GSLO.
Half of the GSLO premium (50%) will be refunded to you if the GSLO is subsequently cancelled before it has been executed. An additional GSLO premium is not required to modify an existing GSLO.
If you wish to place, modify or cancel a GSLO you must ensure that you have sufficient available funds in your account to cover any increase in position margin as a result. Failure to pay any GSLO premium due in full may result in your GSLO being rejected or removed.
