"Just a quick one to say I'm very impressed so far :) The documentation for developers is excellent and I've quickly managed to get an app written to do historical downloads. The system is very robust and pretty quick considering the extent of data that's available. The support guys have been very helpful too, in combination with the forums it's been plain sailing so far!" - Comment from Adam

Thank you for clarification


Hello,

today I requested OptionChain for BBD and my application failed on parsing Option name, as some of the returned options had different format.

BBD1918A15 - correct one
BBD11918A15.45 - not correct.

Can you please advice me, if it is an issue on your side, or when this could occurs?

Thank you,
Ondrej

Hello,

I'm doing some simulations and I can't see any daily options data before 2011. Am I doing something wrong, or there are no options data before 2011?

Thank you,
Ondrej

IQFeed Developer Support » Daily not adjusted close price May 3, 2018 02:25 AM (Total replies: 1)

Hello,

My understanding is, that by default historical stock close prices are adjusted. Is there any way how to retrieve daily non adjusted close price for stocks?

Thank you,

Finally I found an issue in the way I called the socket - I called it twice. Now it works without any problems.

Thank you for your support

IQFeed Developer Support » Corrupted structure for historical data Apr 27, 2018 09:42 AM (Total replies: 5)

Hello,

I reused the script from your example, please see enclosed file. The strange thing is, that ENDMSG replaces the beginning of the original message, it is not just in the wrong order - so it looks that it happen already somewhere in the socket - as OnReceive only concatenate strings (in my case it is overwritten).

It happens only when I ask for longer period and only in very few cases. 1 of 300.

Hello,

I'm trying to receive historical data for approx 2000 symbols and after a while some records which I receive are not in correct structure.

It looks like the last row overwrite the first row and the message begins with: 238,!ENDMSG!,
Could you please advice me, what could be the reason? ( I tried to increase socket buffer, but without any improvement)

Thank you,
Ondrej


Hello,

I'm trying to download historical data and after a while, my sw starts failing with the error "11582 Could not connect to History Socket".

It is not always on the same place, sometimes I get 7000 request, sometimes 13k. I'm trying to find historical options so therefore I have so many requests. I have multithread application with 15 threads.

In the IQConnectLog I can see:
