API's come out. Similar to DOE's but not given as much attention because reporting of data is voluntary.
Wednesday at 10:30 is the weekly inventory reports... http://www.eia.doe.gov/pub/oil_gas/..._petroleum_status_report/current/txt/wpsr.txt If you don't know that, don't trade oil or you will get killed.
Well, you can still get killed trading oil even if you know about these reports but at the very least it is probably better to know about the truck coming beforehand rather than after it runs you over .
