Why are volumes for Oct 31 high by a factor of 100 for stocks and indexes?
For many stocks that I looked at and indexes such as ^IXIC the volumes are too high by a factor of 100. MU did not trade 1.54 Billion on Thursday. Your charts are still very buggy, this is another example.
Regarding the MU data inconsistency, we have sent this over for further investigation. Please provide additional information/specific examples of tickers where the volumes differ along with screenshots at firstname.lastname@example.org. Thank you!
