Run Multiple Data in For Loop

sadegh

I am running multiple data in For loop Like this but I can't What's Wrong!
The code

result = []
modpath = os.path.dirname(os.path.abspath(sys.argv[0]))
datapath = os.path.join(modpath, 'data')
for file in tqdm(os.listdir(datapath), position=0):
    if file.endswith(".txt"):
        with open(f'data/{file}') as csv_file:
            row_count = sum(1 for row in csv_file)
            if row_count < 200:
                continue
        path = os.path.join(modpath, f'data/{file}')
        data = bt.feeds.YahooFinanceCSVData(dataname=path,
                                            name=file,
                                            fromdate=datetime.datetime(2019, 1, 1),
                                            todate=datetime.datetime.now()
                                            )
        cerebro = bt.Cerebro()
        cerebro.broker.setcash(100000000)
        cerebro.addstrategy(TestStrategy)
        cerebro.addsizer(bt.sizers.FixedSize, stake=0.05)
        cerebro.broker.setcommission(commission=0.005)
        cerebro.addanalyzer(trade_list, _name='trade_list')
        cerebro.adddata(data)
        strats = cerebro.run(tradehistory=True)
        trade_list = strats[0].analyzers.trade_list.get_analysis()
        result.append(trade_list)

and error is

TypeError                                 Traceback (most recent call last)

TypeError: 'list' object is not callable

@sadegh said in Run Multiple Data in For Loop:

cerebro.addanalyzer(trade_list, _name='trade_list')

addanalyzer method expects the class name as a first argument. It seem the list was passed instead.
