Institutions holding contracts at expiration must close or roll them into the next date. That rollover triggers record volumes and price swings that no economic news can explain. Most of the flow concentrates in the final US hour: expiration-linked orders and index rebalancing all execute into the closing auction. For a retail trader the key point is that these moves are mechanical: they reflect expiration flows, not a change in market opinion.

FREE TRIAL →Triple witching is the third Friday of March, June, September and December, when three families of derivatives expire on the same day: index options, index futures and stock options. That concentration of expirations triggers exceptional volumes and sometimes sharp price moves, with no economic news to explain them.
“Triple witching” covers the simultaneous expiration of index options, index futures and stock options. “Quadruple witching” adds single-stock futures. Those have practically disappeared in the United States since the OneChicago exchange closed in 2020, so both terms now describe the same day.
The tracker above shows the next session with its countdown, plus every date for the current year and the next. The only exception to the 3rd Friday rule: when it falls on a market holiday, expiration moves to the preceding business day.
The expirations are spread across the day: on Eurex, EURO STOXX 50 derivatives settle on the average of the index between 10:50 and 11:00, DAX derivatives at the 12:00 Xetra intraday auction, US index derivatives settle on the Wall Street opening prices (14:30), and US stock options expire at the close (21:00). Note: for three to four weeks a year, when the US and Europe do not switch to summer time at the same moment, the US times shift by one hour. The tracker above always shows the exact times of the next session.
Caution is warranted. The moves in these sessions are largely mechanical: they reflect expiration and rebalancing flows, not new information about the economy or companies. Spreads can widen and technical breakouts are less reliable than usual. Some very active traders seek out precisely this volatility, but if you are starting out, it is better to reduce your position sizes or stay away from the final US hour.
