About
All amounts have a fixed decimal precision of 1e18.
Are timestamps are represented as unix timestamps.
USD and ETH exchange rates of all assets are pulled through Euler directly
All ratios have a fixed decimal precision of 1e27.

}Querying time based aggregates
Every entity that has hourly, daily or monthly in its name can be queried by its ID. The documentation for those is located within each entity. Below lies the rules used to create the required timestamps.
start_of_hour_timestamp
unix timestamp at minute 0
start_of_day_timestamp
unix timestamp at hour 0, minute 0
start_of_month_timestamp
unix timestamp at first day of the month, hour 0, minute 0
