MSQ stands for Major SQ — a specific occurrence of the Special Quotation (SQ), the settlement price used to close out stock-index futures and options at expiration. SQ is the reference price at which these derivatives are settled on their maturity date.

Note: depending on search intent, "MSQ" can also refer to a specific crypto token. Any token-specific details (issuer, supply, market cap) are outside this general explainer and should be verified against official sources. This article focuses on Major SQ as a finance term.

How SQ and Major SQ Work

Index futures and options have expiration months. At expiry, positions are either closed out with an offsetting trade or finally settled at the SQ price — a "special quotation" calculated from the opening prices of the index constituents on the settlement morning.

SQ — because options expire monthly, an SQ is calculated every month.
Major SQ — the occasions (typically quarterly) when futures and options expire at the same time; the concentration of settlement trades draws extra attention.

Why It Matters to a Trader

Around Major SQ, the settlement of expiring open interest (undecided positions) and the rolling of positions forward tend to swell trading volume and raise volatility. The index can move unusually, so for anyone trading futures or options it is a key date on the market calendar.

Crypto perpetual futures have no expiry and therefore no SQ, but dated (delivery) futures do have a maturity and final settlement, and part of the logic carries over. Understanding expiry and settlement mechanics helps with risk management across derivatives generally.

Trading Note

SQ-related trading assumes leveraged derivatives — futures and options. Leverage magnifies gains and losses by the same multiple; an adverse move can cost more than your margin or trigger liquidation. Because prices can turn choppy around expiry and settlement, managing open interest and setting stop-losses matters especially. Trading guarantees no profit — stay within what you can afford.
