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

With AUD/JPY and NZD/JPY rising, +296 yen was realized and by 21:00 it returned to no position. It’s the usual pattern of taking small gains and staying lightweight.

②Kuroyagi-san Evolution AUD/JPY | M30 | MA + BB reversal, averaging down & swaps

+1,201 yen was realized during AUD/JPY’s rise, returning to no position. Being contrarian-type, it waits for a dip.

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

Yesterday’s unrealized +1,625 yen was included, and +2,150 yen remained in the balance. We hold the position after settlement and it’s −252 yen unrealized.

④Index Seven S&P 500・Nikkei 225 | D1 | 7-Logic long-only

One of the positions remains as is; balance and unrealized P/L show no change from yesterday. As this is a D1-design, the index side will observe across days.

⑤Land Builder Rand Builder ZAR/JPY | Swap + compound interest, 3-layer down-avoidance | Pre-release

Forward measurement started today, no entries yet. Balance remains at the initial 1,000,000 yen. This design accumulates land-yen via swaps and compounding, and from tomorrow onward I will list the same figures daily for items ①–④.

■Today’s Summary

FX3EA totals: day-over-day+3,647 yen／ Unrealized + Realized P/L total−252 yen
Index Seven (USD-denominated): day-over-day±$0.00／ Unrealized−$43.00
Land Builder: Balance1,000,000 yen／ Unrealized0 yen（Measurement starts today）

Thanks to the rise in cross-yen, all three FX3EAs closed some positions today. The total unrealized is −252 yen, but compared with the maximum drawdowns of the three EAs (26.58% / 29.03% / 41.61%), this is a balance ratio of less than 0.01%, within the design’s error margin. From tomorrow onward, ⑤ Land Builder will also show day-over-day changes.Today as well, no anomalies in all EAs. Also see you at 9 PM tomorrow.
