Bollinger Channel

A robot is designed for trading on a real account. The robot trades inside a channel formed by Bollinger bands. Trades are only opened with trend, near the border line of the channel. Take Profit is set at the opposite side of the channel. Deals are always by stop losses.

Trading Strategy Characteristics

The robot calculates the channel formed by Bollinger bands. Market entries will be made near the channel borders if there is a sufficient gradient. Profit is fixed on the opposite side of the channel. Since the deals are only opened in the trend direction, the EA tries to close the majority of deals with profit. Losing positions are averaged using additional deals, which are calculated so that their aggregate sum could also be closed with profit. As the deposit grows, the money management is applied to increase the volume of trades to match returns and risk with available funds. Robot testing and use are demonstrated in the video.

Outputs

The default parameters are optimized to trade with the minimal risk on EURUSD H1. The EA was tested with the specified parameters using Alpari real account quotes. Testing showed that the trading robot can start working with the minimum starting deposit of 100$, with a profit of 100% per year in testing. Use of a higher deposit and of the initial lot may proportionally increase profitability. There is potential for its expansion by a simple optimization of some of its parameters.

Usage Tips

No indicators are required for the EA operation. All necessary algorithms are contained in a single EA file. To control the EA operation, you can use the standard Bollinger Bands indicator from the MetaTrader 4 terminal. You can enable or disable placing of opposite positions when the opposite direction entry criteria are met (parameter Open counter positions). If you allow opposite positions, the total number of trading cycles will be increased, while increasing the probable profit and reducing drawdown through locking.

The robot is easily optimizable for other currency pairs and timeframes. Parameters recommended for optimization are marked by (*). I will provide the product buyers with the optimization specifics in a personal message.
