Column description for the static.adam4eve.eu CSV export

---- MarketVolumesRegionHistory ----
Adam4Eve collects volume information from the market orderbooks via CCPs ESI API every 15 minutes and records the sell/buy volume. At the end of the day the volume ranges for that day are calculated and stored as a volume history.
Volume means the amount of items of a commodity available in the market. It is the sum of the item amounts offered across all sell/buy orders and available for possible trades.
The values should therefore not be interpretated as the traded volume, thus the amount of a commodity that actually changed hands.
The data made available here is aggregated on regional level. A4E offers data on station/structure level, too.
