      Hey guys, so, I've backtested the strategy and I'm now ready to try running on IB demo paper account.
      The strategy needs 2 datafeeds - one "live" minutely (the current day from market open), and one daily (with history going back 3 years, so it has to have the historical=True).

      How to add new daily data to the "3 year history" feed after each day ends (market close), so the last day's OHLCV would always be available on the next day's open (along with the history data)? Does backfill work on a feed created with historical=True ?

      What are the possible options for this? Does BT have to be restarted before each market open, or are there other options (i.e. running BT continuously) ?

      Regards

        Also BT could be run continuously, both TWS and TWS Gateway need to be restarted daily (https://financefeeds.com/interactive-brokers-adds-auto-restart-feature-tws-platform/) even with auto-restart feature enabled. It means all the data subscriptions need to be renewed anyway.

        IMHO it is easier ( and cheaper if you run in cloud) to start/shutdown the system on (extended) trading session start/end every day. If in cloud - it even could be easily done using scheduling APIs.

          It's not in the cloud, it's in a local VM, and I know that restarting the bot is easier, however, I was looking for a solution that would allow me to run the bot continuously.

          Actually I've found a very nice function that will probably work - backwards() @ linebuffer.py
          Placed it @ log_data called in each next()/notify_timer() with the current day's date, so if a bar enters data1 - it should remove it.
          So, now waiting for live data to see what'd happen :)
