SPY potential short play

Although SPY accomplished significant gains today, the indicators tell a different story.
1. At the moment, the daily candle appears to be a hammer which signifies buyers unable to keep up with intensified selling
2. The daily ADX is decreasing due to recent selling indicating a slowing uptrend
3. The conversion line is converging with the base line signifying a potential reversal of the uptrend
4. The price is near the previous ATH, a strong resistance until it is cleared with a daily close above it
5. A 5 wave Elliot Wave pattern can be drawn starting Monday. If the price reaches the ATH tomorrow morning there will likely be a correction wave towards wave 4 ending on the 4 month trendline as a support
