We provide you with real-time prices—free of charge. The price displayed is known as the 'last' price—the price at which a trade has occurred at one of the venues from which we source data.
It is important to note that the price displayed in the app is indicative prices, which means that your order may be executed at a slightly different rate than the one displayed in the application. This is directly related to the fact that stock prices can sometimes change significantly in one second/minute. (Markets are dynamic that way!)
