There are several ways in which you can copy another trader. You can automatically copy all the trader's orders such as entry, take profit, and stop-loss. Or you can copy some of them manually simply by receiving notifications of those trades.
In any case, it is necessary to have a trading account, the appropriate software, and devices. MetaTrader is the most widely used trading platform by licensed and unlicensed Forex traders and brokers.
Although this platform has very advanced features, it is easy to use. The confidence it generates is based on its stability and security backed by years of experience.
Both MetaTrader 4 and MetaTrader 5 platforms contain indicators, signal service for copy trading, oscillators, expert advisors, and other technical assistance, as part of their functionality.
