If SPX follows the 2011 script, then it puts in a s-t top at approx 2090 cash and retraces to approx 1950 cash or the 10/2 closing levels...thinking that maybe the ndx hits the highs the day AAPL reports on 10/27...
all just speculation, obviously...
so this is what I have:
2011:
18 td's from low to high (1074.45 - 1292.80) = 218.35 (20.3%)
2007:
40 td's from low to high (1370.37 - 1576.03) = 205.66 (15.0%)
2015: (2nd leg from re-test of Aug lows)-can't find accurate data on Aug 24 cash low...
18 td's from low to high (1871.97 - 2079.68) = 207.71 (11.1%)
