We're looking at how symbol changes & splits are represented in the past, to handle them as they occur going forward, but it doesn't seem that our FDS queries return anything before 2019.

FDS,1,7,20190305 => returns data
FDS,1,7,20180305 => E,50007,No file available.

Prior years going back have the same "No file available", and NASDAQ equities (FDS,1,5) exhibit the same behavior for pre-2019 as well.

Thanks

This format for the data is only available back through May 21st, 2018.

Thanks, is there a list of max available date ranges for the various queries somewhere?

There isn't an explicit list, but IQFeed historical API requests will let you request as much data as you want. If no data is available, the API will just return what it has. In general, minute data is available back to at least 2007. Daily data often goes back further. It varies depending on what symbol and exchange it is. Tick data is only kept for 180 days. My advice is to request whatever you want, and the API will return whatever data it has that fits that request.

Sincerely,
Gary Stephen
