Original Turtle Rules Trader - MetaTrader 5용 expert

Original Turtle Rules Trader EA implements a trading system described in the book "The Original Turtle Trading Rules".

According to the description given in the book, the famous Turtle Trader system consists of the following components:

• Selecting the size of a trading position depending on the current market volatility.
• Entering the market after the fast or slow Donchian channel breakout.
• Skipping the second signal following the first successful breakout.
• Adding new positions.
• Placing and moving stop orders.
• Exiting positions.

In full compliance with the description,

• the system automatically tracks the current market volatility and calculates the optimal trading lot - unit;
• the algorithm visualizes three Donchian channels on the chart: System 1 and System 2 channels, as well as the fast channel for exiting a position;
• the EA skips the channel breakout (regardless of its outcome) if a successful trading signal was implemented before that;
• the algorithm tracks a trade, closes a position after the fast channel breakout or adds positions after specified volatility intervals;
• the EA sets and moves stops.

Instead of closing trades after the fast channel breakout, the algorithm can use the Parabolic SAR system or simply set a take profit.
