The data for that day was complete and clean.\n\n**Instrument:** I used `edgex/trades:ETHUSDC`. The older `ETHUSD` symbol has no data after 2026-08-28, and `ETHUSDC` starts on 2026-09-03, so it looks like edgeX renamed the ETH perp. `ETHUSDC` is the only ETH perp series with data for this day.\n\n**Data check:** The day has all 12 two-hour shards, with 99.2% window coverage, which is this feed's healthy level. The feed has quality problems elsewhere: partial windows up to 2026-09-16 and stale timestamps up to 2026-09-19. None of them touch 2026-09-27.\n- There are 1,440 one-minute bars covering 00:00 to 23:59 UTC, with no gaps.\n- 68,038 trades went into them.\n- The server drops bars built from fewer than 3 trades. None were dropped on this day.\n- There were no bad prints: the largest single 1-minute move was 0.23%, and the close stayed between 2,668.19 and 2,720.79.\n\n**Calculation:**\n- There are 1,439 log returns of the 1-minute closes. The first return uses the 00:00 bar; I didn't reach back to the previous day's last close.\n- The sample standard deviation of those returns is 0.00036721.
