Alpaca backtrader plot issue: I ran into this import issue and found article below, so I applied the code, but same issue not resolved. any one can help please?
My installed matplotlib version is 3.3.1 backtrader 1.9.76.123 python 3.8.5
the entire code posted below:(if you want to run, you need to get your keys at Alpaca.markets)
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()
