NASDAQ Futures Roll Calendar: Quarterly Mechanics Explained

NASDAQ 100 futures (NQ and MNQ) roll quarterly. For position traders holding contracts beyond the most-active expiry, understanding when to roll, how the basis works, and how to minimise execution cost on the roll matters substantially. This guide covers the practical mechanics.

The roll calendar

NASDAQ 100 futures expire on the third Friday of March (H), June (M), September (U), and December (Z). The expiry codes follow standard CME conventions:

• March: symbol H, e.g., NQH26 expires third Friday of March 2026.
• June: symbol M, e.g., NQM26 expires third Friday of June 2026.
• September: symbol U, e.g., NQU26.
• December: symbol Z, e.g., NQZ26.

The most-active contract is whichever expiry is currently nearest. Open interest concentrates in this front contract. As expiry approaches, open interest migrates to the next quarter, the back contract.

When the roll happens

Open interest typically migrates from front to back contract during the second week of the contract's expiry month. By the Thursday before the third Friday (expiry day), the back contract usually carries the majority of open interest. By Friday itself, the front contract is illiquid.

For NQ specifically:

• Roll begins: Approximately 8-10 trading days before front contract expiry.
• Roll peak: 5-7 trading days before expiry.
• Roll completion: 1-3 trading days before expiry.

A trader holding the front contract beyond roll peak risks reduced liquidity and wider spreads when closing.

How the roll process works

The roll is a single combined trade or two sequential trades:

Combined "calendar spread" execution

Some brokers and platforms support the calendar spread as a single instrument, e.g., "buy NQM26, sell NQH26" priced as a spread. The trader executes one transaction; the system handles both legs.

Spread quoting reduces execution risk and ensures the basis is locked at execution. CME publishes calendar spread tick sizes that may be tighter than the individual contract spreads, improving execution quality.

Sequential execution

Without calendar spread support, the trader executes two separate trades:

1. Close the front contract (sell the long position or buy back the short).
2. Open the equivalent position in the back contract.

Sequential execution carries leg risk, between the two trades, prices can move adversely.

For most active traders, calendar spread execution is preferred. Confirm broker support before trading.

Basis between front and back

The price difference between the front and back contracts (the basis) reflects:

1. Implied dividends

The NASDAQ 100 includes dividend-paying companies (Microsoft, Apple, etc.). The futures price implies forward dividends, the back contract trades lower than the front by approximately the expected total dividends between the two expiries.

For NASDAQ 100, expected quarterly dividend impact is typically modest (~10-20 index points for a 3-month gap), reflecting the index's growth-tilt.

2. Cost of carry / interest rates

The futures basis also reflects implied financing cost. Higher interest rates push back contracts higher relative to spot equivalent positions. In current US rate environments, this carry component is meaningful.

For a 3-month NASDAQ futures basis at index 22,000:

• Implied dividend impact: ~-20 points
• Implied financing impact: ~+50 points (at current rates)
• Net basis: back contract approximately 30 points above front

This basis is small relative to typical daily ranges (100-200 points) but matters for traders rolling large positions.

3. Supply-demand at the roll

During the roll window, demand for the back contract spikes and demand for the front declines. Spreads can temporarily move based on roll flows, particularly for very large institutional positions rolling on the same day.

Practical roll execution

For day traders

Day traders typically don't hold positions across the roll. Closing positions at the end of session and starting fresh in whichever contract is most-active simplifies the roll question entirely.

For swing traders

Swing traders holding positions for days to weeks need to plan the roll:

1. Monitor open interest distribution in the days before expiry.
2. Roll to the back contract once it carries dominant volume.
3. Use limit orders or calendar spread orders to control execution price.
4. Avoid rolling on expiry day (Friday), liquidity is poor.

For position traders

Position traders holding contracts for months should:

1. Identify roll dates well in advance and plan around them.
2. Track the basis dynamics, favourable basis during the roll window can produce small but real cost savings.
3. Consider rolling early (1-2 weeks before expiry) if the back contract is already liquid.

Cost of rolling

Each roll incurs:

• Bid-ask spread cost, typically minimal for NQ (very tight spreads).
• Commission on both legs, broker-dependent. IBKR: ~$1.70 per round-trip per NQ contract.
• Basis exposure, closing at the front price and reopening at the back price means accepting the basis differential.

For active traders, total roll cost per quarterly cycle is typically in the $5-$15 per NQ contract range, small but cumulative across multiple positions.

Common roll errors

1. Holding into expiry on the wrong contract

A trader holding the front contract through expiry without closing or rolling faces:

• Cash settlement, for index futures, settlement is in cash to the special opening quotation (SOQ) on the morning after expiry.
• Forced position close, the contract simply doesn't exist after expiry; the trader's position is settled at the SOQ.

Failing to roll means accepting whatever the SOQ produces, which may be far from the trader's intended exit price during volatile open conditions.

2. Rolling at the worst possible time

Trading the roll on Friday morning of expiry produces wide spreads, low liquidity, and adverse pricing. Roll Wednesday-Thursday at the latest.

3. Mismatching contract size on roll

A trader rolling 5 NQ contracts who accidentally executes only 4 on the new contract creates an unintended one-contract directional exposure. Use calendar spread orders to ensure size matching.

4. Ignoring basis impact

The trader who treats the roll as "the same position in a new contract" overlooks the basis differential. The basis is a real cost; account for it in PnL calculation.

Roll calendar resources

• CME Globex calendar, official expiry dates published on cmegroup.com.
• Open interest data, available via broker platforms and aggregators (Barchart, etc.) for tracking the migration window.
• Volume profile by contract, most platforms display volume on each contract; the migration is visible day by day.

Special situations

Quarterly dividend ex-dates

Major dividend ex-dates (typical for NASDAQ 100 constituents) can affect basis dynamics around the timing. Larger dividend names (MSFT, AAPL, etc.) have more impact.

Triple witching

Quarterly expiry is "triple witching" when multiple derivative contracts (stock options, index options, index futures) all expire on the same day. Triple witching produces elevated volume and volatility around the open. For NQ, March, June, September, December expiries are all triple witching events.

Year-end / new-year roll dynamics

The December-to-March roll occurs during a period of elevated tax-related portfolio activity. Basis dynamics can differ from other roll windows.
