FA (Financial Advisor, IB) setup in Backtrader

  • M

    New to Python as well as algo world, but learning and trying.

    Tested my FA paper trading account and it works fine. It is rather easy!
    However, I am getting small error in the commission report, I guess. This could be easy for coding experts. Please take a look at the error and I appreciate if someone can help.

    Further test shows this error is produced if a single order sent to a FA group or FA profile, where it will be allocated or sliced according to the setup in TWS. That group or profile contains two or more sub accounts. However, there is no error when an order is sent specifically to a single account. I understand the code are meant for single account only, but I believe since backtrader is able to support FA account structure, such errors can be corrected.

    Let me be blunt about this: as a Financial Advisor you can consider funding the development of such FA account support.
