When you place an order, we provide an indicative price based on the current market data available at that time. As we execute your order, we gather quotes from multiple financial sources to ensure that you receive the best possible price.
If you place a "Market Order", the last trade price will be displayed. The order will then execute at the best remaining ask/bid price once it is processed. However, there is a risk that the price at which your order executes will be greater than the displayed price.
If your order is a "Limit Order", it will only be triggered when a specific price is reached. It may execute at a better price, which will charge you less to complete the order.
