I have been plotting various markets internal indicators on my charts, such as NYSE New High - New Lows and McClellan Oscillator. However it seems that the data for these stops at around the middle of April 2008. For example the New Highs - New Lows has been showing a constant value of 104 since then.

It is only a problem with me or is it common with everyone?

In case it makes a difference I am using Metastock Pro.
