In my opinion ADX indicator is one of the best trend indicators from MT4 or MT5 terminal. This indicator is powerful, especially it shows pretty good signals on bigger timeframes like H4 and D1. Even alone this indicator can be used as an extra filter for trend direction. I think a lot of people likes this ADX indicator, so now i have an EA based on it. Strategy is simple - sell trade when -DI line is higher than +DI line and buy trade when +DI line is higher than -DI line. It looks quite simple, but with proper settings it can be the really good strategy. Also EA has trailing stop feature, so you will be able to protect your earned profit more securely. There is an reversed option too, it reverses all the signals, buy instead of sell and sell instead of buy trade. It's a free forex robot, you can download it and maybe your will find some good settings on some timeframes and symbols. If you will find out that you need something more in this EA, so ask me and i will update it for extra charge. Have a nice trading with it, i hope you like it.
