Forex Robot Rules:

Long Entry: When Fast EMA crosses Above the Slow EMA.

Long Exit: Exit happens with Short Entry.

Short Entry: When Fast EMA Crosses Below the Slow EMA.

Short Exit: Exit happens with Long Entry.

This robot uses the iMA function to calculate the fast and slow exponential moving average values for the specified symbol, period, and settings. The FastEMA and SlowEMA inputs are used to specify the periods for the fast and slow EMAs. The StopLoss and TakeProfit inputs are used to specify the stop loss and take profit values for the trades.

The robot checks if the fast EMA crosses above or below the slow EMA, and if so, it places a long or short trade using the OrderSend function. The MagicNumber variable is used to identify the trades placed by this robot, so that it can manage them correctly.
