    It's not an error. You have to provide a ticker and to make sense of it, some other options. There is a blog post, for example, which shown: Blog - Live Data/Live Trading

    ./ibtest.py --port 7497 --data0 TWTR --resample --timeframe Seconds --compression 5

    ibtest.py is not something you use to trade/backtest. It is script which is meant to test the different functionalities with the `IBStore.

    There is an article in Medium which describes how to set up your own script (although the only thing which differs from backtesting with the standard setup is the setup of the store to get the data feed and replace the backtesting broker with the live broker) Medium - Interactive Brokers in Python with backtrader

    @backtrader Thanks! Now this message appears. I have the TWS API well configured but I do not know what the problem is.

    The first thing would be that you show what you have executed ...
