Sector breadth overview

Note, there are many 'DANGER!' indicators present.  This is a filter which looks at various parameters such as whether the advance decline line makes a new high when the price does not, the relationships between moving averages of the Weinstein Momentum, the direction of the slope of an average of new highs minus new lows etc.  This filter was tuned in an ad-hoc manner against the S&P500 and NYSE breadth data against the 1987 crash whilst trying to minimize false positives.  Other drops have had more foreshadowing in the data than the 1987 one.  Whether this system is still appropriate since I now calculate my own breadth data against (approximately) the Russell 3000 or whether it is appropriate against other markets is a matter that would take a lot of work to fully understand.  However, it is still a good pointer to declines in breadth across a number of indicators.
