About The Index
The Coin Metrics Bletchley Index (CMBI) Polkadot is an institutionally designed cryptoasset benchmark that accurately and reliably represents a real-time market aggregate USD value for Polkadot.
The CMBI Polkadot aggregates data from the major global DOT/USD markets that conform to the Coin Metrics Market Selection Framework. In doing so, Coin Metrics produces the most transparent, robust and manipulation resistant aggregate levels for customers and markets.

- Real-time (every 1 or 15 seconds): Utilizing the most recent trade data from constituent markets and applying an inverse price variance and 'volume-weighted' median methodology to generate the most timely and accurate pricing.
- Hourly/End-of-Day: Observing trade data from constituent markets over a 61 minute period and applying a time-weighted volume-weighted median to obtain robust and manipulation resistant pricing.
