Thomasz, > I wrote already that I will revisit the IQFeed plugin because they released...
I would highly appreciate that. In the meantime users who want to run Amibroker with IQFeed to display realtime charts with timeframe daily (rather than just intraday/minute data charts) can still use the old IQFeed plugin 1.5.5; of course with an old IQFeed client connector (IQFeed 2.3.0.1). This old plugin has the wellknown problem that an attempted backfill might suddenly hang forever, but as already discussed here on this board and given your credible statements, TJ, the "hanging backfill" problem is very likely caused by inadequacies of the IQFeed API. I think you remember the question whether it would be possible to add some sort of timeout handling and re-attempt a backfill request after a timeout expired. It was a legitimate question, but please note, you're asked such questions because you have expertise as developer, and not with the the intention to blame you for such problems or with the expectation that you fix the problems DTN is responsible for! As for the currently latest IQFeed plugin (1.6.0) offered on the Amibroker website, it would be usable in daily timeframe mode if the data mixup issue was fixed. As described, from the user's perspective it looks as if this problem has nothing to do with the IQFeed API but more with the way how the IQFeed plugin handles concurrent access to its internal data structures, when quotes/time series are requested in daily timeframe mode both from Amibroker's normal charting window and concurrently from the auto analysis mode. Also, another issue with respect to IQFeed plugin (1.6.0) is whether the plugin can cope with requests for invalid symbols. Or put differently, is it ruled out that the plugin can get into an invalid state when there are backfill requests for invalid or expired symbols? This is only a question, not a reported problem. And last but not least, if I remember correctly, IQFeed plugin 1.6.0, together with IQFeed API 4.1.0.0, did not solve the "hanging backfill" problem, but if "data mixup/concurrent access" issue was solved, it would be usable and users could migrate from the old IQFeed plugin 1.5.5 to a newer one. --- In [email protected], "Tomasz Janeczko" <[EMAIL PROTECTED]> wrote: > > Hello, > > I wrote already that I will revisit the IQFeed plugin because they released > new version of API that they say fixes a lot of old problems and I will need to work on it anyway.
