Two other reports to watch out for are the weekly oil reserves report after the market close on Tue and the natural gas report just after lunch (2pm EST?) on Wed. Pls verify - I've forgotten the exact times.
These two reports can really move the oil service stocks around as well, sometimes similar to what the Fed rate announcements can do to the market as a whole.
I used to trade the oil stocks. They are hard to read sometimes and they often do not move with the overall market (sometimes counter even) so you get no help from the common market indicators such as PREM, TRIN, etc.
Also, sometimes useful to watch the near-term crude and n/gas futures, if you can get 'em real-time. Can help identify when something's happening.
Take it for what it's worth from a wannabe trader..
