Here is what we will need to see in the data to confirm a change in market trend has commenced:

1. More new lows than new highs
2. New low daily readings registering triple digit figures, consistently
3. The NH-NL differential must turn negative
4. The 10-d and 30-d average differentials must go negative (this is essentially the first sure sign that the market is changing direction – especially the 30-d diff.).
5. Differential readings start registering figures larger than -300, -400, -500+.

March 2013 NH-NL Readings for NYSE:

1. NYSE New Highs: The number of stocks making New Highs on a specific date
2. NYSE New Lows: The number of stocks making New Lows on a specific date
3. New High –New Low Differential: This is simply the number of stocks making new highs minus the number of stocks making new lows.
4. NH-NL 10d Diff: This is a simple 10-day moving average representing the number of stocks making new highs minus the number of stocks making new lows.
5. NH-NL 30d Diff: This is a simple 30-day moving average representing the number of stocks making new highs minus the number of stocks making new lows.
