Suppose what I previously labeled y,A) is actually y, C, e? That would mean wave e of the triangle has completed and, instead of being wave A, this wave up from Monday's lows is the first impulse wave up, and the massive triangle IVth wave correction from the January highs is over. That would have very bullish implications for SPY.
Either way, after the B wave correction, or wave 2 down, we likely get a strong upmove for wave C or 3.
