For 20 years, it never broke once.

I don’t need flashy profits. What I wanted was a harvester that breaks as little as possible.

Harvesting the golden wheat that ripens on the charts, day after day, steadily.

This is the multi-layer defense EA “Golden Wheat Reaper (GWR) v4.50,” designed to endure every market crash.

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

Thank you for visiting the page of the EA GWR that I developed.

By the way, in the winter of 2019 I made my biggest personal trading mistake with manual trades.

I glued to my smartphone day and night, and when the pound moved dramatically, I removed the stop-loss trailing by thinking “it might come back.”

The next morning, when I woke up and looked at the screen, there was a loss three times larger than I imagined. In that cold room, gripping my smartphone with a dead hush, I felt a blank that I can’t forget.

“I never want to feel like that again.”

I wanted a system that would protect my money and follow the rules even when I’m asleep or at work. So I studied programming from scratch, rewrote code hundreds of times, and built this ‘Golden Wheat Reaper (GWR).’

There are many EAs that boast “monthly profit 100%!” or “win rate 100%!”.

But most of them rely on desperate averaging down with unreasonable lots, and their accounts get wiped out every few months. I could not entrust my money to such dangerous figures.

So I built GWR with the sole focus on never dying, surviving whatever market comes.

I myself have put 8 million yen of my own money into this EA and run it on a real account at GMO-Finest for 24 hours a day. I also publish it in real-time on GogoJungle’s “REAL TRADE,” without hiding anything.

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

【Truth of 20 Years (2006–2026) All-Tick Verification】To avoid cherry-picked data (curve fitting) that looks good only for convenient periods, I used a historical data-specific tool and tested the full 20 years and 8 months from 2006 to 2026 with the smallest time frame, every tick (modeling quality 99.90%, error 0).

Verification period: 2006-01-03 to 2026-09-02（20 years 8 months）

Initial capital: 8 million yen

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

Profit factor:1.49

Net profit earned:＋52,013,183 yen (about 7.5x the capital)

Maximum drawdown:11.36%

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%.”.

During the 2008 Lehman Brothers collapse, 2015 Swiss franc shock, 2016 Brexit, 2020 COVID shake... this history's storms claimed many EAs, but this one never sank more than 11%. The moment the principal fell below 5,150,000 yen from 8,000,000 yen, it never happened in these 20 years.

This is the result I built over 20 years.

【Why doesn’t it die? The multi-layer defense that supports GWR】The reason GWR has survived 20 years is that a defensive mechanism that thoroughly distributes risk is built in from the start in multiple layers.

① Different types of monitors work at the same time (multiple independent entries)

Markets constantly change their faces: range, trend, sudden moves. Relying on a single indicator will always mislead you.

GWR runs independent logics with very different aims simultaneously, covering each other’s blind spots. Honestly, it took the most time to tune the balance of these multiple logics.

② Do not cluster in the same place and self-destruct (20-pip barrier)

The biggest reason averaging-down EAs die is that they take positions too heavily in a narrow price range and cannot move.

GWR is coded so that it cannot open a new position unless it is at least 20 pips away from existing positions. A modest constraint, but it saved me many times.

③ When cornered, abandon greed (hybrid emergency escape)

In times of low positions, it holds profits up to the target take profit (default: TP 6.0 pips).

But when the market moves against and reaches a certain number of positions, GWR stops chasing profits. If even plus one yen is saved after fees and swaps, everyone exits immediately, and the account is reset to a lighter state.

④ Expand and contract with the market (Dynamic ATR)

During storms, the averaging-down width automatically widens to take a deeper stance; in quiet times, the take-profit width shortens for a quick exit. This dynamic grid expands and contracts with the market, and has been the area I have continuously refined since v3.0.

⑤ Do not dive into crashes with bare hands (Daily macro defense shield)

When big events or news drive the market in one direction, I stop forcing counter-trend entries. If the daily 200-day moving average and ATR indicate danger, I stop entries and wait for the storm to pass. A humble but the defense I rely on most.

⑥ Zero-saltout declaration (75-day timeout stop-loss)

The scariest thing about averaging-down is being trapped for months in a non-recovering market, with negative swaps choking the account.

If the position has not returned within 75 days after reaching the maximum steps, the system recognizes a structural change and closes out. Admitting loss to survive, so you can rise again at the next opportunity.

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

You can instantly see the EA’s current state and margin maintenance rate from the chart dashboard. It turns green in normal times, yellow as risk increases, and red when in real danger. This visual reassurance helps you sleep at night.

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

Capital guideline: For every 800,000–1,000,000 yen, start with 0.01 LOT. This setting is dangerous in the event of another Lehman-like shock.

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

Auto compound braking feature (InpUseSmoothScaling): ON

Designed to safely raise LOT by 0.01 each time the balance grows by 2.5 million, to avoid a late surge that could cause self-destruction. A smooth brake is applied in the later stages.

Do not be greedy with LOTs; keep to the default settings as much as possible.

If you don’t rush, and trust GWR’s defenses, time will surely work in your favor.

【In conclusion】I am not a genius programmer or a fund manager.

I am an ordinary office worker who works hard during the day and values time with my family.

That’s why I built this with the standard of “whether I can sleep at night without worry.”

Now I can sleep at night, and during work I hardly think about charts.

I hope this ‘Golden Wheat Reaper v4.50’ brings the same calm to the lives of those who try it.
