Interestingly, all the 3 crashes (2007, 2008, 2011) all had VIX first bottomed at 20 DMA on daily chart, which suggests SPX will drop early next week since VIX hit the same support today. Good luck to everyone!
It seems to me that SPX is in 2008 scenario instead of 2011, due to the following:
1) the daily chart pattern is almost a copy of 10/2008 so far, with lower highs(unable to overcome overhead resistance) instead of higher highs as in 2011.
2) the monthly RSI, stochastic and MACD look similar to 2008 instead of ...
