Bug: cerebro.py generating a type error when importing data.

iHustling

Whenever I try to add my own generic CSV data to my code, I get an error:

Starting Portfolio Value: 10000.00
Traceback (most recent call last):

  File "<ipython-input-17-d193ded4a7a8>", line 1, in <module>
    runfile('/Users/developer/SleeplessCrossover/Sleeplessv1.1.py', wdir='/Users/developer/SleeplessCrossover')

    cerebro.run()

    runstrat = self.runstrategies(iterstrat)

    strat = stratcls(*sargs, **skwargs)

TypeError: 'str' object is not callable

If you guys want to see my strategy, here it is:

# Create Cerebro instance
if __name__ == '__main__':
    # Create a Cerebro identity
    cerebro = bt.Cerebro()
    
    # Add a strategy to cerebro
    cerebro.addstrategy('SleeplessCrossover')
    
    data = btfeeds.GenericCSVData(
    dataname='BTCUSDT.csv',
    
    fromdate=dt.datetime(2019, 3, 23),
    todate=dt.datetime(2019, 4, 12),

    nullvalue=0.0,

    datetime=0,
    high=2,
    low=3,
    open=1,
    close=4,
    volume=5,
    openinterest=-1
)

    print('Starting Portfolio Value: %.2f' % cerebro.broker.getvalue())
    
    cerebro.adddata(data)

    cerebro.run()

    print('Final Portfolio Value: %.2f' % cerebro.broker.getvalue())

Edit: I finally found the issue. It wasn't importing the data, it was me adding a strategy as a string that caused the issue. What I don't understand is, when the cerebro.addstrategy() function does not have a string as an argument I get an error saying there's no variable called SleeplessCrossover.

If you use only the script you posted here, than there is no such variable (no strategy) in the script.

You may want to read Quickstart first to figure out how bt works and what should be in the script.
