IQFeed Datafeed Wish List » Please, add delayed OPRA quotes subscription May 17, 2020 08:40 AM (Total replies: 1)

Please, add delayed OPRA quotes subscription (same as CBOE Indexes Delayed for $2.00, COMEX Delayed for $1.00, NYMEX Delayed ... etc). I do not need real time options, but $50 ($7 OPRA fee +$50 IQFEED RT Options) is too much.
Thank you

Issue: No access to delayed and historical stock options data
Description: I don't have subscription on real-time OPRA options (no need for real-time). I used to use delayed quotes and historical options data rarely. But as of yesterday something goes wrong. No data. No access.

Data and Content Support » TRMYQ - 1 min vs tick data Nov 24, 2014 04:23 AM (Total replies: 2)

More confusing data:
Ticker: OHTR
1 minutes history - no(invalid symbol)
daily history - yes
tick history - yes (but not matching with daily data at all!)

Yes, these are extremely illiquid stocks with a few trades... but it probably shows data integrity problem.

I checked TRMYQ historical data.
There is no 1 min. historical data (invalid symbol) for TRMYQ , but tick data is ok!

Well, and finally what should I do in this case? :

Yes, we have ordered IDs but obviously there is wrong ID for the line starting with "14.08.2012,210000..."!
Apparently this line should be moved to another place (much more earlier).

one more case:

But if I sort lines by ID, I'll get unordered cumulative volume...

So more important question:
What is of greater priority: native line number OR tick ID OR cumulative volume? What should I do if they have conflict with each other?

thx

I found millions and millions discrepancies in the "theoretically" same data (mostly in bidask and cum.volume), which I've got with the 1-2 weeks pause between two downloads.
What is that?

I'm still having the same problem (right part of the line is almost pure output from iqconnect socket; downloaded at different times, hard to say precisely dates):

---->If I'm understanding you correctly, you are saying that you are making two requests for the most recent trade on a symbol and comparing the results.
--->And when doing so, you are getting differing results for the bid/ask prices?

I've made multiple historical requests (at least two) appending my historical tick data files with identical parameters (the same ticker, the same period) at different time (let it be one month ago, end two months ago - sorry, but I have not logs to say precisely) into two different csv files.

It was my mistake (duplicates files), but it allowed me to compare theoretically identical files then.
It should be identical, but not.

Data was "as is" (only date field changed, others field - unchanged! without rounding -> raw text data from socket). I used my command line utility (simple HIT request as I remember), developed 3-4 years ago when I had subscription to IQFeed developer section.
So I compared historical data then.
Let me show another example.
I compared two historical tick files (WinMerge), downloaded at different times for the same ticker (AAN) and period:

There are thousands and thousands of such cases
And I'm sure it's not a client software problem...
Thx

27-03-2012 I've downloaded some history tick data.
Recently I re-downloded history for the same tickers and found multiple discrepancies:

It seems like historical (!!) bid-ask prices are changing continuously for last hist. record (until new last trade appeared).
Could you fix this problem?

Do IQFeed provide correct (fully formed) last record in OHLC history (1 min , 5 min ...) during trading sessions even for non-delayed instruments?
Should I except that last High Low and Close fields will not changed a few moments later, if I re-download recent history again?
Thanks

LG# "lost" ALL(!) liquidity between 28-feb-2011, 28-mar-2011 !
And another 4-5 months in 2010.
It looks like LG# have the same problem - wrong rolling dates.

PS Why is it so hard to keep accurate rolling dates for continuous contracts?

Possible wrong continuous contracts LL# and IE#.

I've downloaded tick history (4 months) for LL# (continuous ) and LLU11 (single).
LL# ~ 2 Mb (ASCII file)
LLU11~ 20 Mb (ASCII file)
difference - 10 times!
It means that continuous contract have less liquidity than single contract (at 10 times!).
Obviously something wrong with continuous contract LL# (as it was for QGC#)
The same is for IE#
