API (API gravity) crude oil inventory data: API is located in api gravity, and the data survey scope only covers the crude oil gas area, so the agency's survey scope is relatively incomplete. API crude oil inventory is the US crude oil inventory level announced by american petroleum institute (API) on Tuesday, which shows how many oil inventories and products there are and how long the supply can last. This data shows the oil demand of the United States by product and region, and also monitors the crude oil production, crude oil imports and refined oil products of the United States. The data is usually released every Wednesday at 04:30 am Beijing time (5:30 in winter).
EIA (American Energy Information Association) crude oil inventory data: EIA is the American Energy Information Association, which actually publishes a large number of data and many important data, and is the first reference data adopted by many crude oil investment institutions. According to personal experience, the spot market of index foreign exchange futures is greatly influenced by EIA, and API is not very important.
