GBPJPY Anomaly v04 ｜ 曜日と時刻だけで撃つ時間アノマリーEA

■ Judgement materials are only a watch and a calendar

GBPJPY Anomaly v04uses absolutely no indicators.

No moving averages, RSI, or Bollinger Bands are stacked.

What this EA watches is “what day of the week it is today and the current time”—that’s all.

In the currency market, there are price-m ändering tendencies that recur regardless of market sentiment.

Underlying demand flows toward Tokyo fix. Forty-ninth-day settlement demand. Month-end rebalancing. Monday open.

These are not predictions of whether the market will go up or down,they are structural biases born from the schedules of people and organizations participating in the market.

This EA cuts out time bands where these biases are observed into 5-minute grid cells and only fires at the statistical survivors110 cells.

■ Ten-year actual performance

Measured values from MetaTrader 4 Strategy Tester (All ticks / 0 misalignment).

All figures are after deducting all trading fees.

【Testing environment】

AxioryAsia-02 Demo (Build 1471) / GBPJPY 1-minute chart / 2016.01.04 – 2025.12.30 (about 10 years)

All ticks (Modeling quality 25.00%)/ Misalignment chart error0/ Test bars 3,719,556

Initial margin 10,000 / Spread 10 (1.0 pip) / 0.05 lots fixed

■ We’ll write out the entire logic

We do not claim “it is a black box.” Here is all of this EA.

【110-cell breakdown】

• Mon 1 o’clock hour (buy) 12 cells — right after weekly open

• Tue–Fri 0 o’clock hour (sell) 48 cells — early in each trading day

• Tue 1–2 o’clock / Wed 1 o’clock (buy) 18 cells — Asia session start

• Gotō-day 0–2 o’clock (buy/sell) 29 cells — settlement demand of the 50-day

• End-of-month Friday 5 o’clock / 20th 17 o’clock / 10th 13 o’clock 3 cells

■ To avoid curve fitting

Parameters for each cell are determined byforward testing (walk-forward).

Using only the most recent 3 years of data for each cell’s optimal combination, then testing the next year, then shifting by one year and repeating

This is repeated for 10 cycles, and the profit/loss during the testing period (data unknown at the time of selection) waspositive in all 10 cycles.

The values loaded in this product are thoseselected by the latest cycle (learning period 2022–2024) and fixed as is.

We do not search for the best year or overall optimal combination.

The selection is built with the discipline that only information available at the moment of firing is used.

Additionally, among the 110 cells,104 cells converge to the same parameters (take profit 20 pips / stop loss 20 pips / hold 120 minutes).

Forward testing continued to yield the same answer across years, indicating that the parameters sit on a broad plateau rather than sharp peakson a broad plateau.

■ We also disclose weaknesses

Please know before purchase which market conditions this EA struggles with.

1. Profits are biased toward the later period

2016 and 2018 were losses for the year. 2017 was almost flat.

The biases observed in the time bands this EA captures depend on market participant composition and trading hours conventions.

The most profitable period in the last 10 years was the most recent 3 years, and fund settings assuming this state should be avoided.

2. Relies on server time

This EA triggers based on the server time of the account. Brokers with a time difference from the testing environment will fire in a completely different time window, and the above performance will not be reproduced. Please confirm server time before implementation.

3. Firing times skew toward quiet periods

Most entries occur around date changes. During this time, spreads tend to widen, and results may differ by account type.We recommend accounts with narrow spreads.

4. Stop loss does activate

During the testing period, 535 occurrences, 17.7% were stop-loss exits. The design accommodates up to 20 pips stop loss.

■ In conclusion

This EA does not rely on market forecasting.

What exists is a collection of observed facts: “on this day of the week at this time, market participants’ circumstances tend to bias prices.”

Because of that bias, performance will disappear when the bias disappears.

We publish year-by-year performance and weaknesses without concealment so you can use it with full awareness.

Use the ten years of actual data and the underlying tendencies as part of your decision-making.
