A quick note related to the Fire post....

I just came across this Bloomberg piece, Five Charts That Explain Crude Oil's Sudden Nosedive Toward $45, which provides some charts and data on last week's oil market panic.  The charts include a look at technical analysis, showing that WTI broke through some low measures which would cause technical traders to sell; action in the options market focused on puts with strike prices of $45 and $46; and a change in the forward price structure from contango to backwardation, which they suggests shows a move from bullish to bearish sentiment.  

It should be another interesting week. Will prices break lower, or will OPEC and Wall Street be able to defend the current low?
