Futures Settlement vs Last Price: Why Closes Disagree

Published November 8, 2026 · View Markdown

Two screens can show the same futures contract and trading date, yet disagree about its close. Before blaming a bad feed, check what “close” means. The last transaction and the exchange's daily settlement are different price references, and they need not match.

This distinction belongs in a futures trading automation specification. A rule that compares a daily close with a threshold needs a defined price series. In an AlgoWay futures alert workflow, record that choice alongside the chart contract and execution contract. Correct symbol mapping does not settle the question of which price the strategy measured.

Three prices with three jobs

As CME explains in its mark-to-market introduction, the exchange establishes an official daily settlement using the contract's specified procedure. Methods and observation periods depend on the product. Do not apply a remembered settlement window from one contract to every market.

A calculation based on trading during a designated period can differ from a later transaction. An average can also differ from the last trade inside that period. Neither difference, by itself, proves an error. The relevant question is whether the published value follows the applicable procedure.

The close setting on a TradingView futures chart

TradingView offers Use settlement as close on daily interval for supported futures and continuous contracts. Its settlement-versus-last help page says the setting affects daily and higher-timeframe bars and is enabled by default. Use the SET control or the chart setting to select last prices instead where the feature is available.

The switch does not change intraday data. TradingView also documents that Watchlist, Details and Screener use settlement prices, so disabling settlement on the chart can leave those displays different. If the control is absent for a particular futures symbol, do not assume the same choice is available there.

This gives you a focused diagnostic: compare the same dated contract, trade date and session, then inspect the daily close setting. A daily candle and the last intraday candle are not automatically interchangeable observations.

How a small difference changes a condition

Suppose a hypothetical contract has a daily settlement of 5,010 and a final transaction of 5,014. Your written rule says to enter only when the daily close is above 5,012.

• Using settlement: 5,010 is not above 5,012, so the condition is false.
• Using the last transaction: 5,014 is above 5,012, so the condition is true.

The four-point difference is small enough to overlook on a chart and large enough to reverse this decision. These numbers demonstrate a data-definition problem; they are not a tested strategy or a claim about returns.

A close-based average or return calculation can likewise differ when its input changes. This is a consequence of the arithmetic, not a claim that every indicator or every alert will change. Record the actual series used by the script, including any separately requested data. A visual setting alone is not a complete audit of a custom script.

Settlement profit is not an exit fill

For a simple carried position, daily mark-to-market compares successive settlements. Suppose you hold one long contract with an illustrative value of $10 per point. Yesterday's settlement was 5,000 and today's is 5,010. With no position changes, the settlement-to-settlement gain is 10 points, or $100, before fees. Using the last trade at 5,014 would instead produce a $140 price comparison. That is a different calculation, not an extra $40 received from closing the position.

Intraday entries, exits, fees and broker statement conventions require their own reconciliation. Keep executed trade prices separate from daily marks. Daily settlement also differs from final settlement at expiration; CME's final-settlement explanation describes the expiring contract's cash-settlement or delivery process.

Write down the price before automating the rule

For the next comparison, retain the exact contract month, trading date, session, timeframe, close definition and time the value became available. A historical settlement reference should not be treated as information available before it was published. CME's settlement-report notes also distinguish the calculated settlement field from other report fields; read the field definition instead of relying on the column's familiar name.

Then compare the condition's input with the outgoing alert and the eventual execution record. If the signal uses a reference price for a limit order, a later market must still make that order executable. The related guide on why a touched limit price may not fill covers that separate question. A settlement is a useful measuring stick. It is not an offer to trade.
