First, please check these results

From 2003 to 2026, about 23 years, USD/JPY M5Tick Data Manager measuredbacktest results.
These results cover all market conditions, including the Lehman Shock, COVID shock, and historic yen weakness.

The 23-year backtest created with Tick Data Manager shows a modeling quality of 99.9, making it a reliable backtest that accounts for spreads and slippage.
Under that environment, win rate exceeded 80%, while the maximum drawdown was 3.83%.
In other words, as you can see from a completely upward-trending balance graph over 23 years, while maintaining a high win rate of over 80%,
even in the worst period, only 4% of the balance was lost.
This is truly an outstanding low-risk, high-win-rate EA.
Of course, there is a reason for these results..
(By the way, with compounding ON, it would yield over 14 billion yen in profits! Since lot sizes are unlimited, this is seldom achievable in reality...)

Why this performance is possible

This EA is not simply a mechanically trading EA.
Three-layer, four AI filters filter trades, two types of settlement modes are automatically adapted to market conditions.

① Three-layer, four AI filters select only “profitable trades”

Entry candidates pass all four gates below to be actually traded. (the count is derived from backtests)
Entry precision is so high that averaging down is not used, achieving an 80% win rate.

② Two settlement modes are automatically used according to market conditions

Mode-selection AI chooses the most appropriate settlement method for each trade. This is the main feature of this EA.
The two settlement modes are not simple TPSL settlements; they monitor technical indicators and dynamically adjust TPSL to aim for big profits and small losses.

In crescent moon mode, a profit-protection function is also built in.
Additionally, this mode includes profit protection.

③ Confidence-based lot sizing (can be turned OFF in settings)

Instead of trading all positions with the same lot, the AI automatically adjusts lot size based on the confidence of each trade. Confident trades get larger lots, cautious trades get smaller—focusing capital on high-quality opportunities (feature added in ver.7).

If ON, it automatically scales to the user-set base lot.
Note: “Confidence” is calculated from price data such as RSI, so due to price differences between brokers, the same trade may have different lot multipliers, which may slightly differ from the official account lot sizes (this is a natural behavior of the mechanism). If OFF, the lot remains fixed.

④ Thorough tuning for USD/JPY M5 to earn irrespective of market conditions

This EA is not a generic EA for all currency pairs. Focused on USD/JPY M5 and optimized solely for its price movement characteristics.

By narrowing to one currency pair, it achieves accuracy unattainable by generic EAs.
Mikazuki does not depend on a specific market direction.Whether USD/JPY rises in a yen-weakening environment or falls in a yen-strengthening environment, it consistently generates profits. In fact, backtests show that during downturns (yen appreciation) annual profit and win rate tend to be higher.Buying in uptrends and selling effectively in downtrends—this bidirectional design enables this stability.

These complex logics and AI training data mean the EA source code runs to 49,522 lines!!!

Operation Guide

Recommended settings and operating information to use this EA with confidence.

①Lot settings

Mikazuki allows separate settings for buy and sell lots. You can freely adjust risk allocation for both rise and fall of USD/JPY.

② Compounding feature to accelerate assets

This EA includes an automatic compounding feature that increases lots as profits grow, aiming for snowball-style asset growth.

Risk tolerance (0.10–0.50, initial 0.20)

This value decides how aggressively to increase lots when compounding is ON. Roughly, it indicates what portion of funds you are willing to endure as temporary drawdown. Higher values speed up growth but also deepen drawdowns.

③ Parameter settings

All parameters are tuned to perform best with default (optimized) settings.

Generally no changes are needed. This EA is USDJPY・M5 focused.

④ Server time settings (broker time adjustment)
This EA is designed based on the official forward broker server time (Winter GMT+2 / Summer GMT+3, US daylight time).
If your broker's clock differs, these four parameters are used to correct it.For most MT4 brokers in Japan, the default values operate as is.
