Daily Futures Settlement and Mark-to-Market: Reconcile the Cash Flow

A valuation event and an open position

Futures have an exchange-defined daily settlement process. That reference supports the calculation and transfer of daily gains and losses. CME's mark-to-market introduction explains the principle. Exact settlement windows and formulas must come from the current rules for the particular contract, because an old educational example is not a current trading timetable.

A daily settlement is different from an offsetting trade. The account can receive or pay cash while still holding the same number of futures contracts. It is also different from final settlement, which handles the contract at the end of its life.

Follow two contracts through three marks

Suppose a hypothetical trader buys two contracts at 5000.00. Each contract changes by $5 for a one-point move. The first settlement is 5006.00, the next is 4998.00, and the trader subsequently closes at 4999.00.

Illustrative long-position cash/P&L reconciliation

Interval	Price change	Calculation	P&L
Entry to first settlement	+6 points	6 × $5 × 2	+$60
First to second settlement	−8 points	−8 × $5 × 2	−$80
Second settlement to close	+1 point	1 × $5 × 2	+$10
Total	−1 point overall	$60 − $80 + $10	−$10

The direct entry-to-exit check is (4999 − 5000) × $5 × 2 = −$10. It agrees with the sum of interval changes. Adding the −$10 lifetime result to the three interval results would count the same price movement twice.

Actual statements may display or post these categories differently, but the economic reconciliation remains a useful check. If quantity changes during the sequence, divide the ledger into intervals with the appropriate position size rather than applying the final size to every earlier movement.

Why cash timing matters

A position can have an unfavorable daily cash adjustment before its eventual exit. Sufficient collateral and account funding must be available under the broker's rules along the path, not only after an imagined profitable ending. An ultimate profit forecast does not pay a current margin requirement.

Daily settlement gains also do not make the remaining exposure risk-free. Tomorrow's price movement can reverse them. The margin guide keeps collateral requirements separate from money-per-point exposure.

Read the report's reference price

When comparing account reports, identify whether an open-position P&L field is measured from original entry, prior settlement or another daily reference. Keep posted variation, trading fees and conversion adjustments in separate columns. A difference in presentation can otherwise look like a difference in strategy performance.

Use balance and equity reconciliation for account totals and cash versus physical final settlement for expiration. For copied positions, compare the actual contract, quantity and fills first; a settlement ledger cannot prove that two accounts held equivalent exposure.

If the ledger fails to reconcile, first check quantity changes, the sign for short positions, contract multipliers and whether charges have already been included. Those concrete checks are more useful than assuming that every report should display identical daily P&L fields.
