IQFeed Developer Support » IQFeed client update backwards compatibility Oct 24, 2017 02:44 PM (Total replies: 2)

Hi Tim,

makes sense, just wanted to verify as I could not find it in written form in the docs, maybe I overlooked though.

Anyway, this is great and thanks!

IQFeed Developer Support » IQFeed client update backwards compatibility Oct 24, 2017 10:35 AM (Total replies: 2)

Hello,

We're using client version 5.2.5.0 and it's asking to upgrade to 5.2.6.0. We're also using protocol v5.1. Will new IQFeed Client still work for protocol v5.1? In general how does IQFeed Client and protocol versioning relate to each other (if any) and how should we know if there are breaking changes in the release?

Thanks Tim!

IQFeed Developer Support » Duplicate records for historical data Oct 12, 2017 03:42 AM (Total replies: 2)

We are trying to retrieve 1 hour interval historical data for several symbols, but apparently we receive records for same interval twice and this is happening for symbol HG, however for symbol BD everything looks fine. Attached you'll find the log output from our software.

Any help would be appreciated!
