No trade is made... what's wrong with this code?


  • Hi. I think I can't find any problem with my data but my cerebro.run() doesn't yield any trade execution at all though the graph is coming out well with cerebro.plot.

    #Since the time interval is 10 minutes so I set compression as 10 and timeframe as "Minutes"
    data = dataFeed(dataname='ticks3.csv',timeframe=bt.TimeFrame.Minutes, compression=10,sessionstart=datetime.time(9, 0), sessionend=datetime.time(15, 10))#, timeframe=bt.TimeFrame.Minutes, compression=60) #dataFeed(dataname='ticks3.csv')

    #I put the codes like this below
    cerebro = bt.Cerebro()
    cerebro.adddata(data)

    startcash=10000
    cerebro.broker.setcash(startcash)

    class SmaCross(bt.Strategy):
    params = dict(
    pfast=4, # period for the fast moving average
    pslow=9 #30 # period for the slow moving average
    )
    def init(self):
    sma1 = bt.ind.SMA(period=self.p.pfast) # fast moving average
    sma2 = bt.ind.SMA(period=self.p.pslow) # slow moving average
    self.crossover = bt.ind.CrossOver(sma1, sma2) # crossover signal
    def next(self):
    if not self.position: # not in the market
    if self.crossover > 0: # if fast crosses slow to the upside
    close = self.data.close[0]
    #size = int(self.broker.getcash() / close)
    self.buy(size=1)
    elif self.crossover < 0: # in the market & cross to the downside
    self.close()
    cerebro.addstrategy(SmaCross)

    cerebro.run()
    portvalue = cerebro.broker.getvalue()
    pnl = portvalue - startcash

    #Print out the final result
    print('Final Portfolio Value: ${}'.format(portvalue))
    print('P/L: ${}'.format(pnl))

    #Finally plot the end results
    cerebro.plot(style='candlestick',iplot=False)

    First step would be to reverse your data so the time increases from top to bottom.

    Use backtiks as described above on the page to post code blocks.

  • @ab_trader Thank you so much! I really appreciate your help:)( I haven't been able to fix this for like 2 months and now it was solved)
