The chart below shows a long-term Point & Figure chart for the S&P 500. Each box is 10 points and a 30+ point move is needed for a reversal (3 boxes). This chart starts with the rally off the November 2012 low. The blue bullish support line was drawn as soon as the X-Column surged above the red bearish resistance line (in November 2012). Rising at a 45 degree angle, this line defines the uptrend until broken. There was had a triple bottom sell signal with the break below 1930, but this occurred above the line and was countered with an immediate surge back above 1930. Support in the 1820-1830 has been affirmed with the October surge and this is the area to watch going forward.
