Alpaca backtrader plot issue:我遇到了这个导入问题并找到了这篇文章,所以我应用了代码,但同样的问题没有解决。有人可以帮忙吗?
我安装的 matplotlib 版本是 3.3.1 backtrader 1.9.76.123 python 3.8.5
整个代码贴在下面:
from matplotlib.dates
import (HOURS_PER_DAY, MIN_PER_HOUR, SEC_PER_MIN,MONTHS_PER_YEAR,
DAYS_PER_WEEK,SEC_PER_HOUR, SEC_PER_DAY,num2date, rrulewrapper,
YearLocator,MicrosecondLocator)
import alpaca_backtrader_api
import backtrader as bt
from datetime import datetime
#import matplotlib
ALPACA_API_KEY = "XXXXX"
ALPACA_SECRET_KEY = "XXXX"
ALPACA_PAPER = True
class SmaCross(bt.SignalStrategy):
def init(self):
sma1, sma2 = bt.ind.SMA(period=10), bt.ind.SMA(period=30)
crossover = bt.ind.CrossOver(sma1, sma2)
self.signal_add(bt.SIGNAL_LONG, crossover)
cerebro = bt.Cerebro()
cerebro.addstrategy(SmaCross)
store = alpaca_backtrader_api.AlpacaStore( key_id=ALPACA_API_KEY,secret_key=ALPACA_SECRET_KEY,paper=ALPACA_PAPER)
if not ALPACA_PAPER:
broker = store.getbroker() # or just alpaca_backtrader_api.AlpacaBroker()
cerebro.setbroker(broker)
DataFactory = store.getdata # or use alpaca_backtrader_api.AlpacaData
data0 = DataFactory(dataname='AAPL', historical=True, fromdate=datetime(2015, 1, 1), timeframe=bt.TimeFrame.Days)
cerebro.adddata(data0)
print('Starting Portfolio Value: %.2f' % cerebro.broker.getvalue())
cerebro.run()
print('Final Portfolio Value: %.2f' % cerebro.broker.getvalue())
cerebro.plot()
