# Reported Open Interest

## Overview

The open interest in U.S. dollars for various aggregations of futures markets and option markets. These metrics are available for assets, exchanges, exchange-assets, and pairs. These metrics are referred to as reported because the input data is reported open interest from centralized.

## Data Sources and Methodology

The input data source for the reported open interest metrics is open interest collected from centralized exchanges in Coin Metrics's coverage universe. The open interest is reported by exchanges in contract units and are converted to U.S. dollars and summed over the interval defined in the metric name.

Let us define the following notation:

* $$\mathrm{Q(T)}$$: open interest in contract units at time $$\mathrm{T}$$.
* $$\mathrm{S}$$: size of one contract (e.g. how many underlying units each contract represents).
* $$\mathrm{MarkPrice(T)}$$: mark price of the contract at time $$\mathrm{T}$$.
* $$\mathrm{ReferenceRate}\_{\mathrm{size}}(T)$$: price of one unit of the size asset in U.S. dollars at time $$\mathrm{T}$$
* $$\mathrm{ReferenceRate}\_{\mathrm{margin}}(T)$$: price of one unit of the margin asset in U.S. dollars at time $$\mathrm{T}$$.

The reported futures open interest metrics `open_interest_reported_future_*` are defined as:

$$
\mathrm{OpenInterestReportedFuture}(T)
;=;
Q(T)
;\times;
S
;\times;
\mathrm{ReferenceRate}\_{\mathrm{size}}(T)
$$

The reported option market value volume metrics `open_interest_reported_option_*_market_value` are defined as:

$$
\mathrm{OpenInterestReportedOptionMarketValue}(T)
;=;
Q(T)
;\times;
\mathrm{MarkPrice}(T)
;\times;
S
;\times;
\mathrm{ReferenceRate}\_{\mathrm{margin}}(T)
$$

The reported option notional volume metrics `open_interest_reported_option_*_notional_*` are defined as:

$$
\mathrm{OpenInterestReportedOptionNotional}(T)
;=;
Q(T)
;\times;
S
;\times;
\mathrm{ReferenceRate}\_{\mathrm{size}}(T)
$$

Coin Metrics calculates these metrics for various entities: assets, exchanges, exchange-assets, and pairs. For each entity, the markets used as input in the calculation differ. The entity defines a set of markets that are used in the calculation. The metric description further filters to a specific subset of markets as defined in the metric description.

* For **assets**, the markets included are any market where the asset is either the underlying base asset or underlying quote asset and match the markets in the metric description.
* For **exchanges**, the markets included are any market that is listed on the exchange and match the markets in the metric description.
* For **exchange-assets**, the markets included are any market that is listed on the exchange and the asset is either the underlying base asset or underlying quote asset and match the markets in the metric description.
* For **pairs**, the markets included are any market across all exchanges that contain the underlying pair and match the markets in the metric description.
