I&#39;ve had it for multiple quotes btw

Here&#39;s what I noticed:<br><br>Every YQL call, the price fluctuates.&nbsp; about 5-6 times out of 10, it will grab the right prices and the wrong prices at other times.<br><br>I dont know if it makes any difference, but I am grabbing 100 quotes at once.<br><br>Can anyone from the YQL team shed some light on this issue.<br><br>thanks

Dimmer,<br>We say the exact same thing. It seems like possibly one server&#39;s data is stuck on the close prices from August 2nd, 2011. I think it just depends on which server in the data farm returns the data.<br><br><br><div class="quote "><div class="quotetop ">QUOTE<cite>(Dimmer Summer @ 12 Aug 2011 2:11 PM)</cite><blockquote class="quotemain">Here&#39;s what I noticed:<br><br>Every YQL call, the price fluctuates.&nbsp; about 5-6 times out of 10, it will grab the right prices and the wrong prices at other times.<br><br>I dont know if it makes any difference, but I am grabbing 100 quotes at once.<br><br>Can anyone from the YQL team shed some light on this issue.<br><br>thanks</blockquote></div></div>

I am obviously seeing this too. &nbsp;Does anybody think this is related to the recent issue where stock quotes were returning&nbsp;<span style="font-family:arial, sans-serif;line-height:14px;font-size:small;">505544000.00 for all values at about the same rate as these Aug 2 values are showing?&nbsp;</span>

I&#39;m having the same issue, I have to refresh, to get pull valid data.

Sadly, I have moved from the YQL free service to a paid service.&nbsp; The quotes are very important for my app.

I am looking at prices for crude futures and they are all wrong. &nbsp; I was thinking this would be a nice service to use, and I am totally shocked at the quality of this data.&nbsp;<br><br>Yahoo needs to either discontinue their service or fix it, because it is a complete&nbsp;embarrassment. &nbsp;Who did you switch to, I would be interested to know.<br><br><div class="quote "><div class="quotetop ">QUOTE<cite>(Dimmer Summer @ 17 Aug 2011 10:58 AM)</cite><blockquote class="quotemain">Sadly, I have moved from the YQL free service to a paid service.&nbsp; The quotes are very important for my app.</blockquote></div></div>

any follow ups on this? &nbsp;What good paid services are there?

Dimmer, I&#39;m trying to pull real-time stock data. What app and service has worked for you?<br><br><div class="quote"><div class="quotetop">QUOTE<cite>(Dimmer Summer @ 17 Aug 2011 10:58 AM)</cite></div><blockquote class="quotemain">Sadly, I have moved from the YQL free service to a paid service.&nbsp; The quotes are very important for my app.</blockquote></div>

I&#39;ve had similar issues with yahoo etf quotes whether I use YQL or download a csv. &nbsp;I&#39;ve also found that, for a big data set, the occasional day will get dropped.
