V3.0.0 CHANGES (as compared to version 2.0.2)
- Implemented tracking of streaming symbols accross multiple clients via S,STATS
- Uses new method of staring up IQFeed (command line), asynchronous operation (no wait for plugin)
- Aux fields initialized properly to zero
- Native 64-bit version implemented
IMPORTANT: this plugin uses NEW IQFeed Client 22.214.171.124
ftp://www.dtniq.com/beta/iqfeed_client_4_8_1_7.exe or higher. Older Client API versions will not work.
The biggest improvement can be seen when using 1-, 5- and 15- second databases.Thanks to new IQFeed API the plugin does not need to download tick data anymore to construct second bars as second bars are now natively supported by IQFeed API. This dramatically decreases the amount of data that needs to be downloaded and increases the speed of backfill for N-second databases.
Also improved is backfill in other intervals.
