McClellan Summation Index  is one of my favorite indicators when trying to find bottoms.

Notice the areas shaded in green on the chart, very good accuracy.



It is not as useful in signalizing tops though but current read of 1130 caught my attention.

It is highest since May 2013 and 3rd highest in past 3 years. Is there something to take away from it?

All index reads above 1000 during that period are shaded in orange and only one time it marked the swing top.
