gazonkos - MetaTrader 5용 expert

The automated trading system Gazonokosilka (in Russian means "Lawnmower") can provide often little profits. Stop Loss and Take Profit parameters are set to tight values so that trades could be closed in case of small price movements. But the EA should not be scalping, the optimum scenario is one-two trades per day.

Trading rules of the system:
1. Enter at the roll back of the price movement
2. Exit at Stop Loss or Take Profit

Therefore we first need to determine the price action or momentum (a variety of options is available). Then wait for the rollback (various options) and enter the market.

The EA is designed to test on EUR/USD H1 and allows experimenting with the underlying trading system. The EA analyzes price movement inside the bar, therefore testing should be performed in the "Every tick based on real ticks" mode. It is very important.

The code is well commented and structured, so even a beginner can understand it.
