● EA Overview

YY DoubleDragon (Double Dragon) MT5is a fully automated trading tool that has been discovered and systematized as a breakthrough by applying a“breakout method”through next-generation AI statistical analysis in the USD/JPY market, where this pattern frequently occurs daily.

It has been thoroughly tested with actual market data (real ticks) from 2015 to 2026 (11+ years), and only in phases where a reproducible edge was confirmed across range markets, major moves, currency interventions, and sharp declines, does it take positions based on strict rules.

The design philosophy of this EA isto maximize profits from growing price moves and mechanically exit with small losses when price moves do not grow..

By thoroughly eliminating the risk of the “steady small loss then big win” typical of high-win-rate scalping EAs, it achieves high win rate with medium frequency trading while keeping drawdown at an extremely low level.

● Rules for revising the EA sale price

This EA is planned to incrementally revise (increase) the price as certain quantities are sold.We recommend purchasing early.

The ultimate target is 200,000 yen.

● Basic specs

USD/JPY is one of the most traded currency pairs in the world,with low spreads and high liquidityand experiences price movements driven by clear economic backgrounds, such as differences in monetary policy directions between the US and Japan (policy divergence).These patterns recur often.In recent years, with persistent trends driven by the divergence between the Bank of Japan's policy and the US Federal Reserve policy, the market environment has continued to produce sizable trends. This EA deeply analyzes the unique tendencies of USD/JPY and is designed on an edge confirmed by statistical significance using long-term data spanning 11.5 years, including ranges, major moves, interventions, and sharp declines.

It distinguishes itself from ideas relying on indicators without fundamental justification, focusing on the economic rationale of “why it moves there.” It also contributes to portfolio diversification by combining with instruments that behave differently, such as gold or EUR/USD.

● Backtesting results (2015–2026)

These figures are not the result of overfitting by tuning parameters to a specific period. During development, it was confirmed that parameters optimized for recent years underperform in older periods (2015–2017, times of BoJ negative interest rate, Brexit, US presidential election, etc.).Therefore, we adopted parameters robust across the entire 11.5-year available period.We have implemented robust parameters that hold across the full history.

Note: The auto-lot feature (Auto Lot) has only been tested on USD and JPY accounts. For other currency denominations, we recommend operating in fixed lot mode.

● Benefits

1. High profit factor (3.73) and recovery factor (51.07)
Even the Sharpe ratio reaches 18.52, reflecting profit stability. The design cuts losses early and lets profits run, ensuring a steadily rising equity curve.

2. Extremely low drawdown (about 4% maximum)
Over an 11.5-year horizon, the maximum drawdown stays around 4% of equity. Since losses per trade are small, you can operate with minimal psychological burden.

3. Hedged design that captures moves in both directions

4. Simple risk management with no Martingale or averaging down
To protect the account, it does not employ averaging down or martingale logic that risks ruin from a single large loss.

5. High win rate (over 90%) × small losses with trailing exit
Does not rely on fixed take-profit lines; uses trailing to extend profits when trends grow. Combines high win rate with strong trend-trailing behavior.

6. Clear operating panel + one-click cleanup
A dashboard panel on the chart shows running status, current month P/L, and monthly win rate at a glance. The “ENTRY LINE ALL CLEAR” button lets you reset all pending orders with one click and restart smoothly.

Stable monthly accumulation of about 20–25 trades and extremely low drawdown—a reliable, step-by-step EA that emphasizes reproducibility.

● Demerits and countermeasures – Please read carefully.

To understand the EA’s characteristics correctly, we candidly describe its drawbacks as well.
Knowing the drawbacks in advance helps prevent improper actions due to unexpected floating losses.

Demerit 1: Execution quality of the broker heavily affects performance

Reality:Average holding time is about 6 minutes, and the design aims to enter/exit quickly by catching price momentum. Brokers with wide spreads or slow execution may prevent the strategy from performing as intended.

Mitigation:

• Please use ECN/RAW spread brokers with proven execution quality.
• Before live trading, verify execution quality (slippage, etc.) using a demo or small live account.

Demerit 2: Tolerance to sudden moves like interventions or key official statements is only validated by backtests

Reality:Past interventions by BoJ in 2022 and 2024, and a sharp drop in Aug 2024, showed good results in individual tests, but these are based on historical tick data backtests. Actual interventions may widen spreads and cause slippage, which backtests cannot fully replicate.

Mitigation:

• In periods where major policy announcements or interventions are anticipated, monitor floating P/L yourself.
• Again, use brokers with low spreads and reliable execution quality.

● Who this EA is suited for

● People interested in USD/JPY behavior that leverages economic fundamentals
● People who dislike dangerous money-management methods like martingale
● People who prefer a monthly cadence of about 20–25 trades with steady compounding and
● People seeking a stable equity curve with minimized drawdown
● People interested in portfolio management by combining multiple instruments and multiple EAs

● Who this EA is not suited for

● People who want to multiply funds in a short period
● People who want to run the EA without monitoring at all
● People who would stop trading at the first floating loss
● People considering using on brokers with wide spreads or poor execution

● About EA parameters (GMT settings)

This EA recalculates SR (support/resistance) re-evaluation timing based on your broker’s GMT offset. Since server times differ by broker,please manually enter your broker’s current GMT offset into the input parameter (DD_GMTOffsetHours).

(Example: For XMTrading, enter “3” during daylight saving time and “2” during standard time. Please ensure correctness.)

Please revise this value when your broker switches between daylight saving and standard time.

Other EA parameters do not generally require changes. Changing the Magic Number or adjusting lot size is up to the user.

• Forex/CFD trading involves price volatility and the possibility of losing principal.
• We recommend starting with a demo account, and in live trading, starting with low leverage.
