XTB offers one type of execution:
Market execution
Market orders are executed at the current market price. It means that the displayed price is not guaranteed and the buy/sell order will be based on the best price that XTB can offer at a given moment, without a need for any additional confirmations from the Client, even if the market price has changed since the time of placing order (to the advantage or disadvantage of the Client). The advantage of this type of orders is that there are no problems associated with their execution. The disadvantage is that the client is not sure at what price the order will be executed (especially in the presence of high volatility in the markets).
In other words: market orders guarantee execution*, not price.
*In extreme cases, e.g. due to a lack of available liquidity or an inability of XTB to determine the current market price, the market order may be rejected.
Bid-Ask Spread
The spread on financial instruments on Standard accounts is variable and depends on many factors, such as: volatility of the instrument, available liquidity, time of the day, economic situation or XTB margin. The Company exercises the greatest care to ensure that the spread offered is consistent with the target values presented in the Financial Instruments Specification Tables.
