Some good indicators

Here I'm looking at the Put/Call ratio and when the majority are bullish or bearish. Notice the correlation when it has been time to be bullish and time to be bearish. currently the ratio is at an important crossover mark to indicate we should be bearish. The VIX has also taken a large spike and we have all time highs in NASDAQ and QQQ.

Be careful out there and always do your own research.
