Real users should carefully review JustMarkets' slippage. It depends on the market. During normal trading hours, when there aren't significant fluctuations, slippage is minimal and essentially negligible, with the difference between the order price and the executed price remaining relatively close. However, when important data releases arrive, such as the non-farm payroll figures or the Federal Reserve's decision, slippage can become quite painful. When the non-farm payroll figures came out, the price I saw when placing my EUR/USD trade differed by 3 pips from the actual executed price, significantly reducing my potential profit. Furthermore, slippage is more noticeable on mobile than on desktop, so be mindful when placing orders on your phone. However, slippage on a demo account is comparable to that on a live account, providing a useful reference for practice.
