SP500 1871-2015 Using all time lows of 1877 (cycle #0) & 1932 lows (cycle #1), cycle window #2 pointed to the crash of 1987 Currently cycle #3 is pointing towards end of year 2015. This is not a top call or a bottom call, it is an observation how three previous lows all had a cycle relationship and am wondering if the next will will have the same results.
