Cosa imparerai:
Berkshire Hathaway Class B (BRK/B) trades across 3 distinct sessions spanning roughly 15 hours daily, but only 6.5 of those hours carry the liquidity that professional traders prioritize. Picking the wrong window can mean wider spreads, slower fills, and price gaps that erode edge before a trade even develops.
Sessioni di trading
BRK_B — Sessioni di trading Forex (UTC)
Orari di apertura e chiusura di ciascun mercato.
Orari in UTC. Gli orari effettivi possono variare per broker e ora legale.
BRK/B operates on three sessions tied to US Eastern Time and NYSE rules:
| Session | UTC Open | UTC Close | Liquidity Level |
|---|---|---|---|
| Pre-Market | 10:00 | 14:30 | Low |
| Regular | 14:30 | 21:00 | High |
| After-Hours | 21:00 | 01:00 | Low–Moderate |
The Regular session (14:30–21:00 UTC) is the only window where NYSE's full order book is active. Pre-market began expanding in 2010 as ECNs grew, but volume on BRK/B before 14:30 UTC rarely exceeds 5–8% of the daily total. After-hours trading resumed post-21:00 UTC can react sharply to earnings releases — Berkshire typically reports quarterly results after the close — but bid-ask spreads during that window can be 3–5x wider than midday Regular session levels.
For position traders holding multi-day swings, session boundaries matter less. For intraday entries and exits, they define execution quality entirely.
Two sub-windows within the Regular session consistently produce the tightest spreads and highest volume on BRK/B.
Opening window: 14:30–16:00 UTC (10:30–12:00 ET / 15:30–17:00 London / 23:30–01:00 Tokyo) The first 90 minutes after NYSE open account for roughly 35–40% of BRK/B's average daily volume. Institutional order flow dominates, price discovery is active, and momentum setups have the fuel to follow through. The first 5 minutes (14:30–14:35 UTC) carry elevated volatility as overnight gaps resolve — entries placed directly at the open carry higher slippage risk.
Closing window: 19:30–21:00 UTC (15:30–17:00 ET / 20:30–22:00 London) The final 90 minutes before NYSE close attract rebalancing flows, index-related trades, and institutional position squaring. Volume spikes reliably above the midday average, and BRK/B's price often makes its largest directional move of the day in this window.
Dead zone: 16:30–19:00 UTC Midday US hours produce the lowest intraday volume. Spreads widen slightly, price action becomes choppy, and breakout signals carry a higher false-positive rate. Scalpers and short-term traders generally avoid this window.
Pulsar Terminal's real-time spread display lets you monitor exactly when BRK/B spreads widen beyond your acceptable threshold — particularly useful for flagging the midday lull or post-close after-hours conditions.
