That's almost exactly where I am. I'm watching that 1/25-26 turn closely, as the model doesn't really turn hard again until mid-July late August. If we aren't at new highs by then I'm 95% sure of the top, if we haven't made a new high by March (55 months from the highest S&P monthly close), I'll be 98-99%. Of course if we make a higher high, I'll be 100% sure that wasn't the top <VBG>.
As with all trades it's risk reward. If I wait until March, I may have missed a good 10+% of the move, so I'm planning to pounce around the 50% retracement, where I'm comfortable with the risk of stopping at 1218, and still leave the majority of a planned 2 year move ahead.
