[amibroker] Re: Amiquote Import does not import a few symbols

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?
