This is a professional trading robot, which implements the classical WPR based trading strategy.

The signal is produced upon exiting of Williams % from the overbought/oversold areas; the levels of those areas will be levels with the values of LevelMax and LevelMin. We buy, as Williams % falls lower than level LevelMax and then rises above it. We sell, as Williams % rises above level LevelMin and then falls below it. Also, the signal can be inverted. 

The EA correctly processes errors, and works reliably in the market. Can work with the initial deposit from $100! It is important to choose the direction of the EA operation: both sides, only buy or only sell.

The Expert Advisor uses the basic concepts, breakeven, trailing, stop loss and take profit, as well as closing by an opposite signal.
