Re: Daytrader 6.5
Using dtn real time. Problem with the "new" decimal quotes. Those quotes are way off base, i.e. aol is at 21 55/64, up 35/128, having opened at 54 7/8. Only occurring with the second phase decimal stocks. If anyone has a fix please post...Thanks.

"How much intraday history does the WOW data service now offer?"

If you pull up an intraday chart for a stock you have not viewed before, you will normally get 6 days of data. It seems that sometimes it is less that 6. I think that is because holidays/weekends are counted in the 6 days (seems like a bug to me.) However, if you change an option to tell the program to increase the number of days to store in your disk cache to say 10 or 30, it will keep that number of day's data for you on your hard drive. Obviously, you can't let more than 6 days elapse between accessing that stock's chart or you will have a gap in your cached data for that stock and the chart will have a time period in it which is blank.

"Does the WOW data service still fill in holidays with the data from the previous trading day?"

I looked to confirm my memory just now and holidays seem to create a row of data in the stored table for that stock, but the values all say 'empty' and there is a blank space where that bar would be on the chart.

On the other hand, for stock indexes (like the NASDAQ composite, etc.), the data from the previous trading day IS used to fill in for that day. Ah, consistency. (Actually, it's never caused me a problem.)

Did I answer your questions ?
