CME gaps: where Bitcoin and Ether futures reopened after the weekend

Until 29 May 2026, CME's Bitcoin and Ether futures stopped trading over the weekend and on holidays, and they often reopened away from where they stopped. That difference is a CME gap. Since then they trade around the clock apart from a two-hour pause on Saturday, so no new gaps form. This tool finds every gap from before that date, measures how often and how soon price came back to close it, and lists the ones still open. It is a Pro Lab tool, part of the Pro and Elite plans.

Using it

1. On a computer, press Pro Lab on the right-hand toolbar; on a phone, open the analysis centre from the chart's bottom bar and choose Pro Lab. Then choose CME gaps.
2. Choose the contract: Bitcoin or Ether.
3. Choose the smallest gap to count: All, 0.25%, 0.5% or 1%. Every figure on the page follows this choice.
4. Read the open gaps in their table, and press Alert me on one to hear when price reaches it.

Reading the results

• The first line says how many gaps closed and within how long half of the closed ones did.
• How soon they closed sorts the gaps into the same day, within a week, within a month, later and still open; By size shows the same for small and large gaps.
• The chart shows the contract's daily closes with a dashed line at the level of each open gap.
• Recent gaps lists the latest ones with their size and how long each took to close.

Good to know

• A gap is read on hourly bars: two bars at least 20 hours apart, the second one's open against the first one's close. It closes when a later bar trades back to that close.
• The futures trade a little above or below spot, so an alert on an open gap is set on BTCUSDT or ETHUSDT at the same percentage distance from the price now.
• AlertaChart's hourly CME history begins on 31 October 2025 and the futures have traded 24/7 since 29 May 2026, so every gap falls between those two dates and no new ones are added.
