So the past two days have seen a good 200+ point move followed by a day of giving those gains completely back. In the S&P500 the chart looks to be forming a triangle pattern. The lows and highs are being slowly squeezed together. The index closed sitting directly on support at 845, with the next level of support present at the last lowest low around 800 to 810.
On a 30 minute chart of the S&P500 these support levels can be seen much more clearly. Resistance levels on the other hand occur at 855 then stronger resistance at 880 where yesterday's high hit its head and rebounded.

The NASDAQ looks much the same on both the daily and 30 minute charts.

The major difference is that the NASDAQ is holding at support levels at 1507 that correspond with the support found at 855 on the S&P. Not quite sure what the significance of this is yet (if it even is significant) but it certainly illustrates the slight disconnect in price movement between the two indices. Other support levels on the NASDAQ are located at 1490 (the equivalent of the 855 level in the S&P) and at 1440 where the most recent lowest low occured on the last downswing in the index. I think all indexes will kind of stumble roughly sideways until the end of next week.
