Beginner question: Interactive Brokers Data not loading

DVX

Hey guys!

I just started using Backtrader and am currently facing a problem with receiving data from IB.

Previously I have been working with IB API, IBridgePy and IBpy already and never faced problems with retrieving data.
My account includes live tick data so it should be no problem to get the data.

import backtrader as bt


class PrintClose(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.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()


def run(args=None):
    cerebro = bt.Cerebro()
    ibstore = bt.stores.IBStore(host='127.0.0.1', port=7497, clientId=35)
    data = ibstore.getdata(dataname='EUR.USD-CASH-IDEALPRO',
                       timeframe=bt.TimeFrame.Seconds, compression=5)
    cerebro.resampledata(data, timeframe=bt.TimeFrame.Minutes, compression=2)

    cerebro.adddata(data) #not sure if this is needed, but commenting it out does not fix the problem

    cerebro.addstrategy(PrintClose)


    cerebro.run()

if __name__ == '__main__':
    run()

This is my current code. TWS API port is set correctly.

This is what I get from my terminal.

Server Version: 76
TWS Time at connection:20201209 17:48:10 MEZ
Server Version: 76
TWS Time at connection:20201209 17:48:18 MEZ
Server Version: 76
TWS Time at connection:20201209 17:48:26 MEZ

I am certain that it must be some really minor thing that keeps me from printing the data,

Thanks in advance for your help,

I would suggest to take a look at the TWS API logs and see if all the data farm connections were OK for example and there are no other error notifications.

Alternatively you may implement the notify_store method in your strategy and print the messages received from the IB store. for example:

    def notify_store(self, msg, *args, **kwargs):
        print('STORE NOTIF:{}', msg)

I've run your code using TWS desktop and got the following output:
