# Price Source Policy

The following describes our policy as the operator of one or more price sources. A price source gathers information about a given pair of assets and transforms it into a single price.


## Relevant Asset Pair(s)

The operator provides price sources for multiple asset pairs listed outside of this policy.


## Data sources

The operator pulls information from sources that are based on global markets with a tendency toward US markets in the case of market divergence. They also tend toward BCH sale price rather than midmarket price.

- Bitpay general rate
- Coinbase midmarket rate

In the case that the operator determines that it would result in a more predictable behavior, the operator may add or remove price sources, attempting to reasonably match the price behavior of the previously published prices.


## Data processing

The operator performs some data processing to ensure availability and consistency of reported prices, including in the case of a market divergence.

Processing is summarized as follows:

- Start with an ordered list of price sources with Bitpay as the first in the list.
- Identify the first available price source
- Average the prices of all further available prices sources with the condition that they are within some percent divergence from the first available.


## Changes

Changes to this policy will be indicated in the change of its cryptographic hash.
