Running StartIBC.bat fails about ibc HOT 5 CLOSED

Ewald Apologies for taking so long to reply. The problem with StartIBC.bat is that it assumes that it’s called from an environment that has called SETLOCAL ENABLEDELAYEDEXPANSION. This command used to be included at the start of this script, but I removed it at some point for a reason that is no longer valid and forgot to put it back. Normally StartIBC.bat is not called directly from the command line, and the supplied script that calls it (DisplayBannerAndLaunch.bat) does indeed call SETLOCAL as required, which is why I didn’t notice the problem you’re having (note to self – test more thoroughly!). So I’ve pushed an updated version to the repo, or you could add this line directly yourself: setlocal enableextensions enabledelayedexpansion after the @echo off statement. The second problem is simply a hangover from the first: because SETLOCAL is missing, the JAVA_VM_OPTIONS variable retains its value between successive invocations of the script and screws things up. My fix also initialises this variable, though it’s not strictly necessary. By the way, is there a particular reason why you want to call StartIBC.bat directly rather than via the higher level scripts?

Ewald Thanks for the explanation, I thought it would probably be something like that. I’m aghast to hear that IBC on groups.io has already been taken! Shucks. I did check a while back and it was still free then, but that group was started on Feb 20 so I guess it must have been longer ago than I thought. It’s a bit embarrassing being pipped at the post by a group with 2 members and only 1 post. Oh well, I’ll have to think again… By the way, thanks for reminding me that I was supposed to be announcing the change of group name today, and I clean forgot. It’ll have to wait till tomorrow now. Regarding moving back to the TWSAPI list, others have also suggested this. I’ll consider it – there are pros and cons. One of the cons is that many users are not programmers and have no interest in the API, so they might prefer a list that’s more focused. Perhaps I’ll post a poll to canvass opinion.

It works splendidly... The reason for StartIBC is to use it in a Python wrapper for IBC. IBC then becomes a 'component' that can be started and stopped at will, with the arguments of choice. The code is here <https://github.com/erdewit/ib_insync/blob/master/ib_insync/ibcontroller.py> . There are some advantages to this over using IBC as a 'service' that has to be running when the API software starts. For example, the API software can start IBC itself and monitor/restart it if required (watchdog). Also there is only one config file needed (with the real password) and with the arguments one can select between TWS or gateway, live or paper, real or edemo etc. Thanks again and congratulations on the successful launch of the IBC project. It's too bad that the IBC name on group.io is already taken by a book club, but I for one would not mind to see the official IBC discussion on the TWSAPI list like it always was for ibcontroller up until some years ago. — You are receiving this because you commented.
