To understand which advisor will be useful to you and, most importantly, profitable, you need to personally test it on a demo account, understand its algorithm and be able to optimize it for trading for certain currency pairs. You also need to be able to understand its settings and be sure to control the risks.
For MT5, popular EAs include Forex Flex EA, Wallstreet Forex Robot, and GPS Forex Robot. Choose one with good reviews, consistent performance, and adjustable settings to fit your trading style. Always test on a demo before live trading.
