These types of trades are not placed with the market immediately. Limits are placed with the market when the price you specified is reached. “At Market Best” orders are orders you have submitted to us to deal at market best when the market has not offered an electronic price.
When your trade is placed you will receive a contract note either by email or post. You can also check your account history by clicking the Accounts menu and then Account History. This will display your most recent transactions.
