I use the TRIN a lot but the last few days the Nasdaq trin has been giving off some odd numbers. I read Chris from RT in RealMoney this morning say it was due to Worldcom incredible trading volume, and I think he is right. Better to use the NYSE TRIN for a while until the Worldcom issue resolves itself.
worldcom is 1/3 of naz volume at some points.. for one stock, it skewed all volume related indicators. you need to ignore them. tntneo
