Same here, looking more like the market wants to keep going up and there usually is some sort of high volume huge move before a trend turns the opposite direction. In this case, I believe the bulls will give it one more push up and then one day when DOW is up around 300, 400 or even 500 points, it will sell off rapidly forming a star or an inverse hammer. That's when you know it's time to start scaling in for the short of a lifetime and be the next Jesse Livermore.
So what's the sell signal? The convergence of the moving averages? The same signal occured on your chart in may 2005 and the Nikkei had the largest rally in ten years.
