For 20 years, it never broke once.

I don’t need flashy big profits. What I wanted was a harvester that wouldn’t break easily.

Harvesting the golden wheat that ripens on the chart, diligently every day.

Designed to withstand every major market crash, the multi-layer defense EA “Golden Wheat Reaper (GWR) v4.50.”

【From the Developer】I am “Komugi,” the developer.

Thank you for visiting the page for the EA I developed, GWR.

Suddenly, in the winter of 2019, I suffered the biggest personal failure in manual trading.

I was glued to my smartphone day and night, and when I was caught in a sudden move of the pound, I removed the stop loss’ reverse order thinking it might come back.

The next morning, when I woke up and checked the screen, there was a loss three times larger than I had imagined. In that cold room, gripping my phone with a numb head, I still can’t forget the feeling of being paralyzed.

“I never want to feel that again.”

I wanted a system that would guard my money, rules, even when I was asleep or at work. So I studied programming from scratch, rewrote code hundreds of times, and created this “Golden Wheat Reaper (GWR).”

There are many EAs that boast “monthly return of 100%!” or “100% win rate!”

But most of them rely on reckless lot sizing and averaging down, and their accounts get wiped out every few months. I couldn’t bring myself to entrust my money to such dangerous numbers.

Therefore, I built GWR with all-out focus on not dying, surviving whatever market comes.

I have personally put 8 million yen of my own money into this EA and run it 24/7 on a real account at Forex Finest. I also publicly show real-time results daily on GoGoJungle’s “REAL TRADE.”

Because I cannot sell something I’m afraid to use myself.

【Truth of 20 Years of Full Tick Testing (2006–2026)】To avoid cherry-picked data (curve fitting), I used a historical data specialized tool and tested the 20 years 8 months from 2006 to 2026 in the smallest time frame with full ticks (modeling quality 99.90%, error 0).

Verification period: January 3, 2006 – September 2, 2026（20 years 8 months）

Initial capital: 8,000,000 yen

Total trades: 90,598 (win rate 69.18%)

Profit factor:1.49

Net profit earned:＋51,...1,833 yen (about 7.5x capital)

Maximum drawdown:11.36%

No discrepancy chart error: 0

What I want you to see most is not the 50 million yen profit, but“The maximum drawdown over 20 years was only 11.36%.”This is the number.

From the 2008 Lehman crisis, 2015 Swiss Franc shock, 2016 Brexit, 2020 Covid shock... through all the historical storms that have toppled many EAs, it never sank more than 11%. The principal 8 million yen never dropped below 5,150,000 yen in these 20 years.

This is the result I built over time for 20 years.

【Why doesn’t it die? The multi-layer defense supporting GWR】The reason GWR has survived 20 years is that the safety measures that distribute risk are built in from the start, layered multiple times.

① Different types of guards work simultaneously (multi-independent entries)

Markets constantly change faces: range, trend, sudden movement. Relying on a single indicator will mislead.

GWR runs independent logics with different aims at the same time, covering each other’s blind spots. Honestly, tuning the mix ratios of these multiple logics took the most time.

② Don’t cluster and self-destruct at the same place (20-pip boundary)

The biggest cause of dead-napping EAs is having too many positions in a narrow price range and becoming immobile.

GWR is coded to require at least 20 pips away from existing positions before opening a new one. A subtle restriction, but it saved me many times.

③ If pressed, abandon greed (hybrid emergency exit)

In quiet times with few positions, it keeps taking profits up to the target (default: TP 6.0 pips).

But when the market moves against and positions reach a specified number, GWR gives up chasing profits and switches to an emergency mode to exit all positions, including transaction costs and swaps, resetting the account.

④ Expand/contract with the market (Dynamic ATR)

When the market is stormy, it automatically widens the grid to hold deeper; when calm, it tightens the take-profit to escape quickly. This dynamic grid adapts to market breathing and has been continuously adjusted since v3.0.

⑤ Don’t dive into big drops empty-handed (Daily chart macro defense shield)

When big events or news push the market strongly in one direction, I stopped forced counter-trading. If daily chart 200-day moving average and ATR indicate danger, I halt entries and wait for the storm to pass. A humble but trusted shield.

⑥ Zero-hold decree (75-day timeout stop loss)

The scariest thing about averaging-down is getting trapped for months and choking the account with negative swaps.

If it has not recovered within 75 days after reaching the specified maximum level, the system exits, recognizing the market structure has changed. Accepting loss to survive allows a new chance to rise again.

⑦ State visible on the chart (1 real-time cockpit)

You can instantly see the EA’s current state and margin maintenance percentage from the chart dashboard. Normal is green, warning is yellow, danger is red. Visual reassurance like this helps me sleep at night.

【Recommended capital and lot settings】Based on 20 years of backtesting, the safest golden ratio is set as default.

Capital guideline: For 800,000–1,000,000 yen, start with 0.01 LOT. This setting could still be dangerous if a Lehman-like event recurs.

Same as me (compound interest setup increasing by 0.01 LOT every 2.5 million yen): ON — This setup is much safer.

Automatic compound interest braking feature (InpUseSmoothScaling): ON

Balances increasing by 2,500,000 yen raise the lot size by 0.01 safely. This provides a smooth brake so the later surge doesn’t cause self-destruction.

Don’t be greedy with lots; use mostly the default settings.

If you don’t rush, and trust GWR’s defenses, time will be on your side.

【In the end】I’m not a genius programmer nor a hedge fund manager.

During the day I work hard, value time with my family, and am an ordinary office worker just like anyone else.

That’s why I built it with the criterion of, “Will I be able to sleep well at night?”

Now I can sleep normally at night and not think about charts during work.

May this ‘Golden Wheat Reaper v4.50’ bring the same calm to the lives of those who hold it.
