Frequently asked questions

How does a trade get executed?

How a trade gets executed depends on the market you’re trading and the derivative you’re using to trade it. But essentially, when you confirm your trade, we’ll instantly check whether your specified price is still available.

Once we’ve confirmed that we can execute your order according to your specifications, we’ll let you know that the trade is live in our platform. Over 99% of the time, this will happen in less than a second.

What is slippage?

Slippage is when an order is executed at a worse price than where you specified. If you place a buy order in the FTSE 100 at 7500, but it executes at 7502, for example, slippage has occurred – because you’ve bought the underlying market at a higher price than your order.

Slippage can occur in fast-moving markets, when prices move beyond the level you can see on our platform before we’re able to execute your order. There are a few different ways of limiting the risk of slippage in your trading, including using limit orders or guaranteed stop loss orders.
