This service for Element43 calculates various market metrics based on historical data. Data is stored in Postgres and can be retrieved via a gRPC API. Every night it fetches the entire market's history from ESI and calculates the metrics described in its gRPC service description. There might be gaps in the data as there is no history available if nothing was traded.
Issues can be filed here. Pull requests can be made in this repo.
The service's gRPC description can be found [here](https://github.com/EVE-Tools/element43/blob/master/services/marketStats/marketStats.proto.
