Cotton Trading Hours & Best Sessions | COTTON

Cotton trades exclusively on the Intercontinental Exchange (ICE) under a single named session — ICE Regular — spanning 02:00 to 19:20 UTC daily. There are no extended or overnight sessions, unlike metals markets where CME Globex provides near-continuous access. The market closes completely from 19:20 UTC Friday to 02:00 UTC Monday, creating a weekend gap risk that data from 2020–2023 shows can average 0.3–0.8% price displacement on Sunday opens during high-volatility periods. Total weekly trading time amounts to approximately 86.7 hours, compared to roughly 120 hours for Brent crude.

Liquidity in Cotton concentrates during two overlapping windows. The first runs from 13:30 to 16:00 UTC, coinciding with the New York open and the release of USDA agricultural reports — historically the highest-volume period, often accounting for 40–55% of daily volume in a single session. The second window, 09:00 to 11:30 UTC, captures European trading hours when institutional positioning ahead of the US open generates measurable order flow. Compared to the opening hour at 02:00 UTC, the 13:30 UTC window typically sees 3–5x higher volume. In US Eastern Time, peak activity runs 09:30–12:00 ET; in Central European Time, that maps to 15:30–18:00 CET. Traders in Asia-Pacific face the least favorable timing — the 02:00–06:00 UTC window carries lower liquidity and wider spreads.

Spreads on Cotton are not static across the session. At the 02:00 UTC open, bid-ask spreads can run 2–4x wider than midday levels, reflecting thin early participation before US and European desks activate. The tightest spreads historically occur between 13:30 and 15:30 UTC, when US market makers and agricultural funds are most active. USDA report days — typically released at 12:00 or 16:00 UTC — produce sharp, temporary spread spikes of 5–10x normal levels lasting 2–5 minutes post-release. Avoiding limit orders in those windows reduces adverse fill risk. Pulsar Terminal displays real-time spread data directly on the chart panel, making it straightforward to identify when Cotton spreads widen outside the 13:30–15:30 UTC optimal window before placing a trade.
