In trading, an order is an instruction to your broker to execute a trade (open or close a position). In cTrader, creating an order means sending a request to buy or sell a specific symbol under certain conditions. An order contains details like the symbol, volume (lot size), price (for pending orders), and any attached stop-loss or take-profit. Once an order is executed, it results in a deal and potentially an open position. cTrader supports various order types (Market, Limit, Stop, Stop-Limit) to cater to different execution preferences.
