I tried this code:

from __future__ import (absolute_import, division, print_function,
                        unicode_literals)
import datetime
import backtrader as bt

# from __future__ import (absolute_import, division, print_function,
#                         unicode_literals)
# import backtrader as bt

# LOGIN TO IB REQUIRED

class St(bt.Strategy):
    def __init__(self):
        self.sma = bt.indicators.SimpleMovingAverage(self.data)

def run(args=None):

    cerebro = bt.Cerebro(stdstats=False)
    cerebro.addstrategy(St)
    store = bt.stores.IBStore(port=7496)
    data = store.getdata(dataname='GBP.USD',
                         sectype='CASH',
                         fromdate=datetime.datetime(2019, 9, 11),
                         todate=datetime.datetime(2019, 9, 12),
                         timeframe=bt.TimeFrame.Minutes,
                         compression=5)
    cerebro.adddata(data)
    cerebro.addstrategy(St)
    cerebro.run()

if __name__ == '__main__':
    run()

And get this as a response to the cell:

Server Version: 76
TWS Time at connection:20210103 17:14:29 Greenwich Mean Time

The kernel stays running for a bit (its latest version) and then no new data comes before it stops. The above message is also what comes before the dataframe when I simply print the IB data it is working fine.

But when I try to produce an indicator/backtest on it; nothing happens. Any ideas on the issue? As IBStore is built in would backtest usually know which columns to use or should I be matching them as if its CSV?

Thanks
