I had problem with yahoo yesterday ( Current and historic worked at least until last downloads around 2:00 EST). About 6 hours after US Market close, Yahoo current failed on all tickers tried. Didn't try historic.  But yahoo web site showed no historic prices for several tickers tried...I don't remember which ones were tried. But this morning, 1/19, things appear back to normal.

    Just another issue with Yahoo.  The date format DEFINITELY changed as I opened the *.aqh files and checked.  If it's back to d-m-y, I'll change the format file back.

      I also don't think its a date issue, Mark, although I am also having 
      trouble with yahoo data lately. Yesterday while trying to 
      download using Amiquote from Yahoo, I got "Failed" for many symbols 
      in my 3000 stock database. It was around 4am so maybe there was some 
      kind of maintenance downtime going on..In addition to that and for 
      several weeks, i have noticed that some symbols which used to have 
      historical data available for them have no data available for them or 
      their data disappears and reappears briefly then disappears. Examples:

      http://finance.yahoo.com/q/hp?
      a=00&b=1&c=2006&d=00&e=19&f=2007&g=d&s=vsth

      http://finance.yahoo.com/q/hp?
      a=00&b=1&c=2006&d=00&e=19&f=2007&g=d&s=whit

      http://finance.yahoo.com/q/hp?
      a=00&b=1&c=2006&d=00&e=19&f=2007&g=d&s=qcom

      VSTH and WHIT do not work for me, i get the following message:

      "Historical quote data is unavailable for the specified date range."

      but QCOM works, and its the exact same link. VSTH and WHIT are valid 
      US stocks and there are others but i am giving a couple of examples 
      only.

      I contacted Yahoo about this problem but they referred me to CSI data 
      and did not indicate they would be addressing the problem. I 
      contacted CSI data but got no response from them. Is anyone else 
      noticing this?
