Front Month
The front month is the nearest-expiring actively traded futures contract. It typically has the highest volume and tightest spreads, making it the default contract for day traders.
The front month (also called the lead month or nearby contract) is the futures contract with the nearest expiration date that still has significant open interest and volume. It is the contract most traders use for day trading because it has the most liquidity.
Why the front month matters
Futures volume concentrates in the front-month contract. As expiry approaches, traders roll their positions to the next contract, and volume gradually migrates. On the rollover date, the next contract officially becomes the new front month.
For index futures like ES and NQ, the front month accounts for the vast majority of daily volume. Trying to trade a back-month contract means wider spreads, less depth, and worse fills.
Front month and price discovery
The front month is where price discovery happens: it reflects the current consensus on fair value. Back-month contracts often trade at a premium or discount (reflecting cost of carry) but follow the front month closely.
When to switch
For ES and NQ, CME publishes an “open interest shift date” (typically around the 3rd Friday of the month before expiry) indicating when the back month becomes the new front month in terms of volume leadership. Most traders switch their charts and orders to the new contract on this date, not on expiry itself.
