IQFeed Developer Support » Order or historic requests Mar 22, 2005 06:04 PM (Total replies: 3)

Is the order of historic data events the same as the order in which you make the requests?

For example if I request 2 days of tick data and then 2 days of daily data will the tick data still come back first? To get around this I have added syncronisation to TeamTrade so it only makes one historic request at a time but this has a few problems when I have multiple charts up.

Some other things I have noticed:

1) When requesting one day of tick data I quite often get no response so I always make sure to request at least two days.

2) When using the historic api for different timeframes I had problems so I needed to create three instances of the historic api, one for day, one for minute and one for tick, it all works fine now but it took me ages to realise using the one historic api for different timeframes was causing my activex crashes.

3) When the user tries to lookup a symbol that doesn't exist the historic api never returns, do you get some other message I can monitor? To get around this I do a symbol lookup before any historic request.

Thanks
