The first is API crude oil inventory data, which was released at 4: 30 am on Wednesday (one hour later in daylight saving time and winter time).
Second, EIA crude oil inventory data was released at 22: 30 on Wednesday night (one hour later in daylight saving time and winter time).
These two data can be obtained free of charge on the financial data website, and there is obvious correlation between them, which is of direct help to the transaction and has been tried and tested.
