Big picture S&P 500!

At this moment we're almost at an important trendline. A trendline connected from the 1929 high and the 2000 high.
Something to consider!!!
Will we cross that trendline? Are we Topping out?
Everybody is Bullish, Almost all the bears trew the towel into the ring.
Nothing can happen, everything is positive, only up up up.
I think it's almost time to think like a contrarian!
So vice versa;-).
Time will tell but this chart is pretty clear to me but provides no certainty.
