SHIROYAGI EA DAILY
Shiroyagi's EA Operation Journal
Issue 30 | 2026-10-12 (Mon)〜10-23 (Fri) | Numbers are published forward measurement on GogoJungle (demo account). Only item ⑥ is real account (self-measured).
Since two weeks have passed since the previous issue, I will summarize the 10 business days from October 12 to 23. During this period, out of the five forward-measured products, there were a total of 25 settlements across four products, and the net profit of FX3EA was +7,810 yen. Of this, +5,178 yen came from 12 settlements of kotukotu-EX. Meanwhile, the stock market collapsed following the positive surprise in the US September CPI on the 14th, and Index Seven closed one long position on the S&P 500 at −$189.45. The unrealized total for FX3EA widened from −24,339 yen on October 9 to −29,496 yen due to evolves in Shiroyagi-san’s Evolution version carrying over three new positions.
■Market during this period
The US CPI for September released on the 14th (US time) showed a total year-over-year increase of +3.7% (forecast +3.6%), and core CPI excluding food and energy rose +2.6% (forecast +2.5%). Both exceeded expectations, which spurred concerns about continued monetary tightening and selling in tech stocks led by semiconductors, resulting in the S&P 500 closing at 7,718.94 (down 86.51 points, -1.11%) from the previous day. The next day the Nikkei Average fell to 64,425.95, down 3,318.34 from the previous day (largest drop in three years). On the 16th the S&P 500 stood at 7,659.44 (−84.62, −1.1%), down 152.10 points (−1.9%) for the week from the 9th close. On the same day, Bank of Japan Governor Ueda was reported to continue raising policy rates as inflation approached 2%, while the USD/JPY remained around 158 with little movement.
On the 19th, the S&P 500 rebounded as tech stocks that had been sold off the previous week were bought back,7,690.73(+0.41%), but due to crude oil prices rising on geopolitical tensions in the Middle East, Friday the 23rd closed at7,623.68(−39.75, −0.5%), for the week down −35.76 (−0.5%). From the 9th close of 7,811.54 to two weeks later, it fell by −187.86 (about −2.4%). The Nikkei closed on the 23rd at62,693.16 yen(−214.68 from the previous day), down from the 9th close of 69,030.92 yen by −6,337.76, and TOPIX stood at3,965.81(−31.69), down from 4,104.81 on the 9th by −139.00. Yahoo! Finance’s rate shown at 19:00 on the 25th (Sunday, NY close on the 23rd due to market holiday) shows USD/JPY at9.447 yen, AUD/JPY at110.333 yen, NZD/JPY at89.372 yen, USD/JPY at156.826 yen. Compared with the values shown in the previous issue (night of the 10th), USD/JPY is down from 158.271 to −1.445, AUD/JPY from 110.596 to −0.263, NZD/JPY from 88.868 to +0.504.
■EA status (10/12–10/23)
“Confirmed profit and loss for the period” is the sum of daily profits and losses on the detail statistics (monthly) pages for each product, excluding results plus swap and fees, from after the previous issue’s data collection date (October 11–23). Balances and unrealized P/L are the values displayed on the page from 19:00–19:37 on October 25 (as the market is closed on the 23rd, NY close level). The comparison target is the values displayed from 20:00–20:45 on October 10 (as described in Issue 29). Annualized figures (this year / cumulative) are for reference with a simple interest basis and use an initial amount.
①sheep6 AUD/JPY・NZD/JPY |M30|Long-only, up to 6 trades
During this period there were no settlements or new positions. We carried over 4 NZD/JPY long positions (placed Aug 21 at 95.113, 0.01 lot; Sept 2 at 92.846, 0.02 lot; Sept 8 at 90.578, 0.03 lot; Sept 30 at 88.309, 0.05 lot; total 0.11 lot). The unrealized P/L improved from −21,203 yen to −17,297 yen as NZD/JPY recovered from 88.868 to 89.372. The official operation chart shows a temporary drop to about −6,374 yen on the 20th, then widening again after the 22nd (approximate chart reading). Balance-to-equity ratio is about 1.0%, with the actual maximum drawdown at 226,351 yen (26.62%), which is well below 10% of balance.
②Kuroyagi-san Evolution AUD/JPY|M30|MA + BB reversal, averaging down & swap
As of the 9th, with zero holdings, during this period there were three rounds of opening and closing positions. One position opened on the 12th at 110.491, settled on the 14th at 110.675, profit +552 yen with swap +40 yen for +592 yen.

The actual maximum drawdown is 1,245,840 yen (29.13%), which is less than 1% of balance. The win rate upper figure is 70.13% (2512/3582), Profit Factor 1.17.

Including fees for 12 lots of −1,764 yen (−147 yen per lot), the balance change is +3,414 yen, matching the difference (1,273,670 yen → 1,277,084 yen). [Post-reflection] The three positions opened on Oct 1 at 9:47, Oct 6 at 11:42, Oct 8 at 17:59 had settlements earlier than the previous issue, but at the data collection time of the previous issue, there was no open price shown and the initial trades began displaying as “Updating results.” The earliest portion of the trade history at the time of acquisition showed four lines of “Updating results,” with no number of lots or entry price. Unrealized P/L moved from −3,136 yen to −4,761 yen, which is 0.4% of balance, and the actual maximum drawdown was 202,772 yen (41.61%), about 2.3% of balance. Win rate 73.36% (603/822), Profit Factor 1.63.
④Index Seven S&P 500, Nikkei 225 |D1| 7 logic long-only

A position opened at 00:00 on the 12th at 7,836.07 was closed on the 18th at 7,646.62 after CPI-related declines, yielding −$189.45. Among the trade history, this is the largest per-position loss since measurement began, and the top-loss statistic shows −$189.00. A position opened at 15:00 on the 15th at 7,704.02 was closed on the 21st at 7,739.39 for +$35.37, and at the same time a new position (0.01 lot) was opened at 7,739.42. Unrealized is −$110.00. Account balance decreased from $10,438.00 to $10,341.00, a drop of $97.00.

Win rate 46.43% (13/28), Profit Factor 1.37, Maximum drawdown 38.91% ($428.00).
⑤Rand Builder ZAR/JPY|Swap + Compound Interest · Downward protection 3 layers
At 16:06 on the 16th, two 0.05 lot positions opened on the 9th at 9.560 and on the 15th at 9.520 were settled at 9.590, resulting in a profit of +500 yen plus swap +46 yen for a total of +546 yen as per the calendar numbers.

Position count increased from 9 positions totaling 0.58 lot to 13 positions totaling 0.78 lot (8 positions from Aug 25–Sep 14 at 0.53 lot and 5 positions since Oct 16). The top positions figure in the upper statistics shows 13. Unrealized is −17,892 yen to −23,028 yen as the USD/JPY fell into the 9.4 range. The initial capital was 1,000,000 yen, about 2.3%, and the design maximum drawdown (including unrealized) around 22.5% is only a small fraction of that.

⑥ Rand Builder (Real Account)FXTF・ZAR/JPY |H4 Active | Self-measured (MT4 screen)
From here on, this is not the GogoJungle forward measurement but the MT4 screen of Rand Builder being operated in the FXTF real account. The numbers are copied as displayed in MT4. The comparison is the difference from the last data extraction (10/10 20:57).
In the real account, EA2 settled 2 positions.

EA1’s 8 trades (from Aug 26 to Sep 10, total 1.35 lots) showed no activity over the period, while Rand Builder’s unrealized P/L widened to −19,842 yen due to holdings increasing to 13 positions as USD/JPY declined. Margin maintenance dropped from 1130% to 852%, and the estimated margin call changed from 4.428 to 4.423.
