Jakub,

Can you please post the main code flow you use to connect to IB and trade? I have the same problem with my paper account.

Thank you.

oops , mistake ..

here is the entire code sample:
# Create a cerebro entity
cerebro = bt.Cerebro()

# load symbol list from file
with open('list.txt', 'r') as f:
    reader = csv.reader(f)
    tickers = list(reader)

for ticker in tickers:
    # Create a Data Feed
    data = bt.feeds.QuandlCSV(
        dataname=ticker[0]+'.csv',
        fromdate=datetime.datetime(2013, 1, 1),
        todate=datetime.datetime(2016, 12, 29),
        adjclose=False, reverse=True)
    # Add the Data Feed to Cerebro
    cerebro.adddata(data)

the data was added using cerebro.adddata
for ticker in tickers:
# Create a Data Feed
data = bt.feeds.QuandlCSV(
dataname='ticker[0]+'.csv',
fromdate=datetime.datetime(2013, 1, 1),
todate=datetime.datetime(2016, 12, 29),
adjclose=False, reverse=True)
# Add the Data Feed to Cerebro
cerebro.adddata(data)

I added the data source with
data = bt.feeds.QuandlCSV(dataname="+ticker[0]+".csv",...)
but when calling print(order.data._name) I get the name of the ticker for datas[0] every time, regardless of the order sent to the print command, BTW all other parameters are displayed OK, only the _name is the same.
it should be basic and intuitive to get the ticker symbol.

but data attribute does not include the ticker, or am I missing something?
what is the data attribute for the ticker symbol?

How can I tell which ticker symbol was opened or closed when notify_order is called?
