@kjiessar It's all locked down. Some users here made a github repo Backtrader2 for bug fixes. You may wish to follow that. Otherwise, Backtrader is what it is for now.

@ultra1971 thanks to @dasch i can use
pip install git+https://github.com/ultra1971/backtrader_ib_insync

as a installation method

@hercp, at RTB 5sec level TWS api still deliver a OLHC bar.

But the TWS api implementation under 5 sec deliver price based on tick data. The IBStore (based on IBPy2) pull tickers with tick code= 233 for non "CASH" symbols, take a look into function def reqMktData() and IBData feed take this and calculate a price usinf function def _load_rtvolume():

The IB API tick type documentation is here:
https://interactivebrokers.github.io/tws-api/tick_types.html

@vladisld It was quite useful. Thank you.

Also, have you had a usecase where you're having data resampled to different timeframes (like you want to get 15m bar of futures and only 5m bar of options for entry based on futures) work?

When I keep all the datafeeds at 5s snapshot, i am receiving data.
But if I keep few feeds at 1s snapshot and few at 5s, I am not receiving any data at all.

Have you faced this?

@li-mike I don't think BT supports "boxed" positions (simultaneous long and short in the same security) but I would think you could fake it by adding the same feed for the security twice and just treating one of them as the long and the other as the short.

@davidavr You can definitely load data in that way. The performance of course will depend on many factors. Let us know how goes.

@zuj what results are massively different?

data feed issue. Change the feed can fix.

Thank you @EMR and @run-out for your answers.

So the original backtrader is officially not maintained anymore.
What about the community forum? I see pinned announcements very outdated (from 2017), javascript issues when posting/reading, missing dates above posts. Is the forum managed by Daniel as well? In that case, I think it would be much better to move the community somewhere else.

@heywhat host is the host IB is running on (127.0.0.1 if you run IB & BT on the same computer). Port is "socket port" in the picture in the link you just gave. Usually, 7496 for live (real) trading, and 7497 for paper trading but check on TWS if this is really the case on your platform. ClientId is your choice, this parameter exist to be able to connect different programs to IB. Please note that clientid 0 is a special kind of API connection (master one, see IB API's doc)

Same here. I forgot my password, and can't reset password by the recovery process.

In addition, I register a new account, but I don't receive the verify email.

And I tried to register with 4 email address, including 3 gmail and 1 hotmail, only one got verify email, which is the current used.

@hyee Search the forums and google with backtrader for extended data feeds and optionally pandas extended feeds

@greenleafone7 Not really sure about it but it seems this parameter is provided for any inherited implementation of CommInfoBase to use.

I figured out with eclipse by configuring with python and i am able to run all python test from the project backtrader-master.
Just to need see how python works.
We can close this thread.
Thank you

iirc it should be enough if you first load the company with the earliest start date. It was long time ago, but I didn't do any special work with the index to backtest thru multiple tickers.

@crazy25000 i'll look into it thanks
