Shiroyagi's EA Operation Diary

Issue 12 | 2026-09-02 (Wed) | Figures are published forward measurements on GogoJungle (demo account). Only item ⑥ is a real account (self-measured).

Today, kotukotu-EX settled 3 times, with a realized P/L of +¥25. After the NZ Central Bank hiked rates, the NZD/JPY fell sharply, and sheep6 and kuroyagi-san evolved version each added one long position.

■Today's Market

The USD/JPY is at 20:509.916 (vs open +0.032). During the day, it ranged from 9.853 to 9.919, after pushing to the 9.85 range in the morning it returned to the 9.9 range. NZD/JPY is92.980 (vs open −1.370) and fell significantly. The Reserve Bank of New Zealand raised policy rates to 2.75% by 0.25%, signaling no further rate hikes for now, which weighed on the NZ dollar, pushing it to the intraday low of 92.762 against the yen. AUD/JPY is114.033 (vs open −0.389) and remained soft; Australia’s Q2 GDP was +0.4% QoQ and +2.1% YoY. The stock index fell sharply, with the Nikkei 225 down64,325.64 (−1,889.70 from the previous day, −2.85%). The Middle East tensions rose with US-Iran exchanges, and rising US long-term yields boosted risk-off selling. The S&P 500 closed on Sep 1 at7,631.47 (−54.67, −0.71% from the previous day). USD/JPY traded in the high 150s to 160, and Bank of Japan Governor Ueda mentioned discussions of rate hikes at the September meeting.

■EA Forward Status

“Today's realized P/L” is the daily P/L shown on the detailed statistics for each product page (monthly). Account balance and unrealized P/L are values shown on the page from 20:35 to 20:55. Annualized rates (this year / cumulative) are reference values based on simple interest and initial amount.

①sheep6 AUD/JPY・NZD/JPY | M30 | Long-only, up to 6 positions

Following the NZD/JPY plunge, at 12:18 today I added a long 0.02 lot at 92.846, bringing the holdings to 2 positions (one from Aug 21 and the new one). The unrealized P/L shown at the top of the page is −844 yen, but the orange line on the official forward chart shows about 785,000 yen, and the difference between realized 788,231 yen and the charted value is roughly the maximum intraday unrealized loss of about 2,400 yen as a rough estimate from chart reading.

②くろやぎさん 進化版 AUD/JPY｜M30｜MA + BB reversal strategy, averaging down & swaps

Today at 9:05 I added an AUD/JPY long 0.03 lot at 114.044, bringing holdings to 2 positions with the Aug 28 position. The unrealized P/L at the top shows −1,873 yen, but the orange line on the official forward chart is around 583,300 yen, and the intraday maximum unrealized loss is roughly 4,000 yen by chart reading.

③kotukotu-EX ZAR/JPY｜H4｜BB trend-following, averaging down & swaps

Today, from 14:09 to 14:10, I closed 3 positions (positions opened at 9:39 today yielded +987 yen; Aug 25 position −1,449 yen; Aug 28 position +189 yen; swaps total 298 yen). The September calendar lists today’s value as +25 yen, and the September section of the monthly analysis remains at 0 yen. The account balance at the top has updated from 1,273,627 yen to 1,277,697 yen (reflecting settlements like Aug 25, not including today’s settled amount yet). The forward history top line shows “Updating results.” and the number of holdings cannot be confirmed on the page. The orange line on the official forward chart is about −271,000 yen, and the intraday maximum unrealized loss is roughly 6,000–7,000 yen by chart reading. Compared to the real drawdown (202,772 yen; 41.61%), this is a smaller level.

④インデックス・セブン S&P500・Nikkei 225 | D1 | 7-logic buy-only

There were no settlements, and today is not listed in the daily calendar. With stock index declines, unrealized P/L widened from −$53 to −$110. The orange line on the official forward chart is about +$170, and the difference between realized $333 and that is the intraday maximum unrealized loss estimated by chart reading at around $130.

⑤ランドビルダー Rand Builder ZAR/JPY | Swaps + compound interest • 3-layer decline defense | Pre-release

Today at 9:49 I added a long 0.10 lot at 9.861, bringing holdings to 4 positions with the Aug 25 and 28 positions. The unrealized P/L at the top shows −1,968 yen; the orange line on the official forward chart is about −1,600 yen, and the difference to realized 964 yen is the intraday maximum unrealized loss estimated at around 2,500 yen. The designed maximum drawdown (including unrealized) is about 22.5%, which is a very shallow level compared to current drawdown.

⑥ Rand Builder (Real Account)FXTF • ZAR/JPY | H4 active | Self-measured (MT4 screen)

In the real account, positions opened at 0:15 on Aug 26 (9.991), 1:00 on Aug 28 (9.959), and 17:06 on Aug 28 (9.918) have been held, and today at 9:05 another position at 9.878 was added, bringing to 4 positions on average around 9.936. The top unrealized is −2,107 yen, which is about 0.2% of usable margin. The chart’s “next buy-in planned” line sits around 9.840.

■Today's Summary

FX3EA Total: Today's realized P/L+25 yen / Unrealized P/L total−5,530 yen
Index Seven (USD-based): Today's realized P/L ±$0 / Unrealized−$110
Rand Builder (Forward): Today's realized P/L ±0 yen / Unrealized−1,968 yen
Rand Builder (Real Account - FXTF): Today's realized P/L ±0 yen / Unrealized−2,107 yen

After the NZ rate hike, NZDJPY fell by more than 1 yen, and AUDJPY also softened; sheep6, kuroyagi-san evolution version, and Rand Builder each added one long position. The total unrealized P/L of −5,530 yen is primarily from kotukotu-EX (−2,813 yen) and kuroyagi-san evolution version (−1,873 yen). Compared to the actual drawdowns of each EA (ranging from 200k to 1.24M), these are modest, about 0.1–0.2% of balance.No anomalies today for all EAs. Also see you tomorrow at 21:00.
