Front Month
The front-month contract is the futures expiry currently carrying the highest trading volume and liquidity, not simply the nearest calendar expiry. It's the contract most trading platforms and prop firms expect traders to hold, since it offers the tightest spreads and most reliable fills.
Why it matters
Some prop firms require traders to stay in the front-month contract at all times. Trading a non-front-month code means thin liquidity, and thin liquidity widens the bid/ask spread even when the last traded price on the chart looks perfectly normal. Because account balance is often marked using the next available bid and ask rather than the last traded price, that wide spread can trigger instant liquidation on both evaluation and funded accounts.

Example
Take the NQ (Nasdaq E-mini) cycle. A front-month contract like NQH6 (March) carries the bulk of volume until traders start rolling forward, at which point NQM6 (June) becomes front month, later handing off to NQU6 (September). CME contracts use standardized month letters: F (Jan), G (Feb), H (Mar), J (Apr), K (May), M (Jun), N (Jul), Q (Aug), U (Sep), V (Oct), X (Nov), Z (Dec). A trader who stays in NQU6 while volume has already shifted to NQZ6 can watch a last price of, say, 26,253 sit next to a bid of 26,104.50 and an ask of 26,171.50, a gap wide enough to move an account against the trader with no price movement at all.
Common misconception
Traders assume "front month" means the soonest contract to expire. It doesn't: it means the contract with the most volume, and during rollover windows these can diverge for a week or two. Traders also assume that loading a continuous chart symbol automatically routes orders to the front month. On many platforms, continuous charts are for display only, and the trader must manually select the correct dated contract code to actually execute.
