I've been posting the daily stock charts since the market sold-off last week. After a big sell-off, the daily charts can give us an idea of what traders are thinking about the market and let us know about the overall confidence level in the market.
Today we had a big sell-off in the SPYs and QQQQs at the end of the trading day. This indicates that traders don't want to hold positions overnight. This indicates a lack of confidence -- or at least a return of caution.
