Today, the S&P 500 went lower than yesterday's low and higher than yesterday's high to close up 1%. We have seen these reversal days before, and those are the most difficult to trade. Luckily, the indicator got us on the right side of the market. Today's bar on the daily candle chart would suggest a bullish reversal, but now the indicator all of a sudden isn't so sure. For trading the S&P 500 tomorrow, Tuesday, May 17th, the Greed and Fear indicator is taking a neutral position.
