"DTN has never given me problems. It is incredibly stable. In fact I've occasionally lost the data feed from Interactive Brokers, but still been able to trade because I'm getting good data from DTN." - Comment from Leighton
"Thank you so much - awesome feed, awesome service!" - Comment from Greg via Email
"I ran your IQFeed DDE vs. my broker vs. a level II window for some slow-moving options. I would see the level II quote change, then your feed update instantaneously. My broker's DDE, however, would take as much as 30 seconds to update. I am not chasing milliseconds, but half a minute is unacceptable." - Comment from Rob
"I have been using IQFeed now for a few years in MultiCharts and I have zero complaints. Very, very rare to have any data hiccups or anything at all go wrong." - Comment from Public Forum
"IQFeed version 4 is a real screamer compared to anything else I have seen." - Comment from Tom
"I just wanted to say how happy I am with your service. I was able to download the API docs last week and I was able to replicate Interactive Brokers historical bar queries and realtime bar queries over the weekend. That was about one of the fastest integrations that I've ever done and it works perfectly!!!!" - Comment from Jason via Email

I was trying to write a function to retrieve the earliest date tick data is available for a symbol. I am sending a HTT request with begin date as a very old date ( 20000101 000000), end date as blank, data direction as oldest to newest and maxdatapoints as 1. Its only returning the latest tick.

But if I supply only the end date with trial and error it does return the oldest date. Is there any other simple way?

Thanks.

Hello,

We will never have more than 180 days of tick history, so today's date - 180 calendar days is going to be the earliest for anything that has been listed more than 6 months.

Beyond that, the maxdatapoints filter is applied before the direction filter so that will not work as you have noted.

You could do a 60 minute interval request for the last 180 days, this would be a much faster request than the equivalent tick request, and the date associated with the first minute available would be the first day of tick data as well, so that may be an option that would work.

Tim
