The Advance-Decline Indicator is a market breadth indicator based on the smoothed difference between advancing and declining issues. The indicator shows when the stock market is overbought (and a correction is due) and when it is oversold (and a rally is due). The Advance-Decline Indicator is a 10-period exponential moving average of the difference between the number of advancing and declining issues.
Hi, when I apply this to SPY I do not see any negative values. Would you have a minute to help me troubleshoot why this is happening?

@HPotter, I really appreciate your quick feedback.
I did not consider that maybe SPY wouldn't have a negative AD line.
But on looking at SPX there are again no negative values, but during the 2007-2008 period the values are outputted in Red, and they are shown as read now again (red since 2012). Are red bars indicative of negative values?
Also, in looking at the script I don't understand where is the information (values of advances and declines) called from. Where is the source?
Thanks again.
