Support for Linux API for the datafeed? Oct 14, 2023 05:16 PM
(Total replies: 33)
That said, I just use wine and it works well (on linux, while using the native X11 graphical desktop on DISPLAY=:10). This works just fine. I messed with Xvfb for a long time before giving up on it and deciding just to use the real X11 display server that is already running. That is much more reliable that Xvfb.

Support for Linux API for the datafeed? Oct 14, 2023 05:06 PM

The context here is that the CME charges vastly more licensing fees for non-display applications, which a linux native connector would probably be considered. So its not really DTN's call, but rather CME's, and DTN is doing its best to avoid having the licensing fees go up massively, which would price the product out of most all of the current customer's reach. Considering that NinjaTrader wrote their own direct to IQFeed client that avoids having to run iqconnect.exe at all, it cannot be that difficult to do yourself if you really want it; not to be too snarky but those Ninja devs are just not that impressive as coders.

Sequential Level1 and Level2 updates. Sep 21, 2023 05:38 PM

Maybe we'll get lucky, and they will add both the sequence tag AND the OrderID to the level1 trade prints. :)

I don't know their internal architecture, so I figured it is worth asking. Maybe OrderID is much easier for some reason. Attaching CME feed documents that show that the OrderID should be available to all new trade messages.[1] [1] Reference https://www.cmegroup.com/confluence/display/EPICSANDBOX/MDP+3.0+-+Market+Data+Incremental+Refresh+Tag+Usage @aQuant: feel free to private message me, if you'd like, and we can compare notes. I'm not saying OrderID on level1 trade prints would get you all the additional information that might possibly be available, but for my purposes in analyzing stop runs and icebergs, I think it suffices.

I've been looking at it, and I think all that is needed is to add the OrderID to the level1 trade prints; as an optional field. In other words, the same OrderID that appears on the MBO summary, adds, updates, deletes... if that OrderID could be made available on the level1 ticks, then doing the rest at the user end would be pretty straight forward. So perhaps this would be a much easier ask than the tag stuff. Perhaps? Worth asking at least... Thank you so much. Kindest regards.

For doing iceberg and stop run analysis using MarketByOrder data, the Rithmic data feed product is superior to IQFeed because of the lack of the feature requested in this thread. To connect the dots, this post https://forums.iqfeed.net/index.cfm?page=topic&topicID=6982 in which Gary Stephen says > Beyond that I'd need to know more about what Bookmap claims IQFeed doesn't do. is entirely understood to mean that IQFeed lacks the feature requested by aQuant in 2014... i.e. IQFeed does not allow us, yet (hopefully soon?), to directly correlate the level1 trade execution history with the changes in the level 2 book. It would be great to give this priority. Thank you.

iqconnect crashes under wine on zeromq exception Dec 6, 2022 10:21 AM

root cause was: Xvfb-run will fill up the /tmp/X$i-lock files and then quietly send your X session into garbage land. I now avoid Xvfb-run and just figure out a free DISPLAY for Xvfb myself and then everything works again. Avoid Xvfb-run is my recommendation; its a garbage bash script. Just use Xvfb directly.

nevermind. I'm not sure what the root cause was, but it seems to be related to X11 stuff under wine and not to iqconnect.

Ah. I see from the zeromq socket.cpp line number indicated that problem has nothing to do with the stack overflow issue which is distinct and so should be ignored; from reading the zeromq source: https://github.com/zeromq/libzmq/blob/538e5d47421f45d88a8b3b005ed9ee4026623a7b/src/select.cpp#L170 Anyway.

iqconnect crashes under wine on zeromq exception Dec 4, 2022 06:32 PM

Hello DTN! I've been running iqconnect.exe just fine under wine, with an X11server for gui, until recently it stopped working. When I investigated, I see it throwing an exception inside zeromq.cpp: Assertion failed: Socket operation on non-socket (C:\Source\IQClient\Shared\third_party\zeromq\zeromq-4.0.5\src\select.cpp:170 It appears there may be a bad cast in the code -- see the stackoverflow below. Or perhaps there is another reason for this? Please advise.

It relies on the first member variable in the zmq::socket_t class being the C zm\ q socket. If you edit the definition of zmq::socket_t to change the member variable order it breaks stuff, badly. – bazza May 29, 2017 at 22:29 comment: Good to know, thanks for user3666197's answer. Although cast an object to a void* pointer making me feel weired zmq reference with an example – r0n9 Feb 16, 2018 at 3:01 comment: Instead of C-style casting you can use socket_t::operator void*() explicitly – stijn May 16, 2019 at 16:43 |
