It seems that the S&P500 has finished an correction to the upside on the 15-minute chart, where wave c is an .
If this count is correct then the S&P 500 will start declining in Primary wave (C) to finish the correction started in May 2015; that will lead to new lows during next year.
If you are looking for a safer trade with higher risk/reward ratio then you can trade sex short with your stop loss above the highest price of wave (B) (almost 2115 or 211.7 on spy ) and looking to take profits around 1800.
