Gap (trou de cotation)
A gap is an empty space on the chart: price reopens higher or lower than its previous close, with no trade taking place in between. It comes from a break in quoting — a weekend, overnight, a trading halt — during which information kept flowing. Not to be confused with a Fair Value Gap, which forms during continuous trading inside a single session. A historic case: Bitcoin’s famous CME gap, created by futures closing over the weekend while spot kept trading 24/7 — it hasn’t formed since the CME moved to continuous quoting on May 29, 2026.
