Nothing happens when running cerebro

Hi, I have written my code just like strategy example but it won't run anything. Please help me.
Strategy code:class TestStrategy2(bt.Strategy): def log(self, txt, dt=None): ''' Logging function for this strategy''' dt = dt or self.datas[0].datetime.date(0) print('%s, %s' % (dt.isoformat(), txt)) def __init__(self): # Keep a reference to the "close" line in the data[0] dataseries self.dataclose = self.datas[0].close def next(self): # Simply log the closing price of the series from the reference self.log('Close, %.2f' % self.dataclose[0])
Datafeed:
class PandasData(bt.feed.DataBase): #linesoverride = True # discard usual OHLC structure # datetime must be present and last #lines = ('Signal',) params = ( #('dtformat', '%Y-%m-%d'), #('datetime', -1), #('time', None), ('open', 1), ('high', 2), ('low', 3), ('close', 4), ('volume', 5), #('Signal', 6), ('timeframe', bt.TimeFrame.Days), ('compression', 1), ('openinterest', None) ) # datafields = bt.feeds.PandasData.datafields + ([ # ('Signal')] # )
Running:
ready_data = PandasData(dataname=strategy_data2) cerebro = bt.Cerebro() cerebro.adddata(ready_data) cerebro.addstrategy(TestStrategy2) cerebro.broker.setcash(1000000000.0) cerebro.run()
in the jupyter it gives this:
[<__main__.TestStrategy at 0x150489c3ba8>]
but running in normal file gives nothing. At least I want it to log the close, so, I can make that cerebro is working on my data.
Please help me. Thanks -
Your data feed has not
datetime
parameter.
