"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

IQFeed Developer Support » Possible error in HTX functions series Jun 12, 2018 09:22 AM (Total replies: 1)

Hello,
I have IQFeed API licence and I am seeing this issue in your tick by tick data: cumulative volume and total volume (as released purely by your application) are not the same.
Let me explain myself better: by getting historical future contract tick by tick data using IQFeed API designed function (i.e. HTX,[Symbol],[MaxDatapoints],[DataDirection],[RequestID],[DatapointsPerSend]<CR><LF>) progessive summation of last size tick is not equal in many case to the value you provide inside Total Volume column, why ?

Please, find attached ES futire contract tick by tick data so that you can replicate the issue: the issue is into the "DELTA" column when the value in it is different from zero !!!

Thank you for reading and let me know please
Andrea

Fabio
