I have found the Naz TRIN to be useless as a trading indicator. Just like the Naz TICK is useless. NYSE TRIN is a much better indicator of selling pressure, just like the NYSE TICK is better.
I'm not exactly sure why, but I think that since there are so many fewer companies on the Naz than there was just 3 years ago, we have to adjust completely where we find important levels on any Nasdaq indicator.
For instance, if we get some selling on MSFT, INTC, SUNW and a couple other heavyweights, the TRINQ can jump very quickly. However, if you look at breadth, we could still have a positive A/D. I think this is why we can get unusual spikes in TRINQ, but TICKQ can still remain very subdued. (fewer companies)
I don't even chart TRINQ or TICKQ any more.
