Regardless of today's recovery, we have seen the S&P 500 test 1800 a few times this week, and it cannot get above it. As a result, the current bear flag appearing on the daily chart looks a little more like a rectangle now - the upper level being 1800, and 1770 being the lower end.
The Dow is the weird one right now, as it did clear its December low. Perhaps the appropriate support level would be 15580 - 15600 - at the 23.6 fib level of the wave from November 2012.
I don't really like the way the oscillators look on the daily charts. The hourly suggests downside, but the daily is not offering a high probability of a red day tomorrow. But I guess you could argue that we will enter dip two of the usual double dip into overbought/oversold areas. We'll see. I'm going to be skeptical.
The weekly looks to favor more downside in the weeks to come, but it may pull back upwards in the very short term before continuing the losses. I will probably question the downside if we get too far above S&P 1815.
Also to note on the weekly, there is a parallel channel from 2009 on the S&P 500. It was broken during October, and has just tested the resistance-turned-support. The low for the day made it through, but it did not close below it.
