All legs near the calm-market floor — the cost basis behind the EW6-ZH / ZAK revival holds right now. Floor = median half-spread measured 2026-08-06 (commission-free). "wide" (>3× floor) is
the stress signal that closes the cross-cost advantage; "elevated" (>1.5×) is a watch.

Net = non-commercial long − short (negative = net short the currency). z / %ile are vs the trailing
156-week window; |z|≥1.5 = crowded positioning (a weak, ~3-day-lagged contrarian context — not a
timing signal). Source: CFTC COT (Legacy futures-only) + FRED DEXJPUS + G8 JPY strength.

net adj removes each venue's persistent quote offset (下駄) — a constant offset never converges,
so it is not arbitrage; only the transient part net of 0.7bp can be. "gross incl. 下駄" is the naive
cross-venue difference for contrast; "offset" is the largest persistent per-venue bias. Green = net-adj positive =
a recogniser (not realised — last-look / latency / T&C sit between a quote and money). x-region = non-simultaneous, suspect.
tick charts mid price, per venue, last 30min (recv clock)
Lag = seconds this venue's mid trails its region's consensus (positive = slower feed = the stale/latency-arb target). Same-region only, so network path is netted out.
