      When I run this

      from __future__ import (absolute_import, division, print_function,
                              unicode_literals)
      import backtrader as bt
      import datetime
      
      class St(bt.Strategy):
          def logdata(self):
              txt = []
              txt.append('{}'.format(len(self)))
      
              txt.append('{}'.format(
                  self.data.datetime.datetime(0).isoformat())
              )
              txt.append('{:.2f}'.format(self.data.open[0]))
              txt.append('{:.2f}'.format(self.data.open[0]))
              txt.append('{:.2f}'.format(self.data.high[0]))
              txt.append('{:.2f}'.format(self.data.low[0]))
              txt.append('{:.2f}'.format(self.data.close[0]))
              txt.append('{:.2f}'.format(self.data.volume[0]))
              print(','.join(txt))
      
          def next(self):
              self.logdata()
      
          data_live = False
      
          def notify_data(self, data, status, *args, **kwargs):
              print('*' * 5, 'DATA NOTIF:', data._getstatusname(status),
                    *args)
              if status == data.LIVE:
                  self.data_live = True
      
      def run(args=None):
          cerebro = bt.Cerebro(stdstats=False)
          store = bt.stores.IBStore(port=7497)
          data = store.getdata(dataname='TSLA-STK-SMART-USD',
                               timeframe=bt.TimeFrame.Ticks)
          cerebro.resampledata(data, timeframe=bt.TimeFrame.Minutes,
                               compression=1)
          cerebro.addstrategy(St)
          cerebro.run()
      
      
      if __name__ == '__main__':
          run()
      

      I get

      G:\Git\Personal\Trading_Algo\venv2\Scripts\python.exe G:/Git/Personal/Trading_Algo/bt_test.py
      Server Version: 76
      TWS Time at connection:20200515 13:00:55 EST
      ***** DATA NOTIF: DELAYED
      

      This stays that way with no changes until I terminate the program. However, if I replace 'TSLA-STK-SMART-USD' with 'EUR.USD-CASH-IDEALPRO', it will work, showing everything from the strategy. Can anyone help me out?
