What Is TWAP? Price Benchmarks and Order Execution

A simple price-average example

Suppose a price is sampled once per minute at 100, 102, and 101, with each sample representing an equal interval. The average is (100 + 102 + 101) ÷ 3 = 101. This is an illustrative arithmetic example, not market data.

When intervals are unequal, each price needs the appropriate duration weight. A benchmark must specify its sampling method, time window, and handling of missing observations; the word TWAP alone does not provide those details.

TWAP execution is a different use of the term

A TWAP execution order divides a larger order into smaller scheduled portions. The aim is to distribute execution over time. The final average fill still depends on liquidity, price changes, order settings, and whether the scheduled orders execute.

Coinbase describes TWAP as one of its algorithmic execution strategies. A scheduling method does not itself predict the market or establish that a trade will be profitable.

Check the source before comparing numbers

An exchange trade price, a bid/ask midpoint, and an oracle observation can produce different averages. Two charts labeled TWAP may also use different windows. Compare the instrument, price source, timestamps, interval weights, and data gaps before treating their values as equivalent.

For a market that uses a price benchmark in its resolution rules, read that market's published rules. A locally calculated average is not a substitute for the official result.

Questions to ask about any TWAP value

These checks help explain a number without assuming it is a trading signal.

• Which instrument and price source does it use?
• What are the start time, end time, and sampling intervals?
• How are missing or delayed observations handled?
• Is it a benchmark, an order schedule, or a chart indicator?
• Which source confirms the final market outcome?
