@run-out can you share the code that can runing successful.

thanks for your demo code.
but when i debug the demo, I found the following code is not defined:
plot_results(results,"/home/yun/index_000300_reverse_strategy_hold_day_90.html")
trade_dict_1=OrderedDict()

could you pls give the define.
thanks.

thanks. i will try ...

the SharpeRadio is not correct,how to fix it ?thanks
out put is:
test: OrderedDict([('sharperatio', None)])

    cerebro.addanalyzer(bt.analyzers.SharpeRatio, _name = 'SharpeRatio')
    results=cerebro.run()
    strat =results[0]
    print('test:', strat.analyzers.SharpeRatio.get_analysis())

  

@run-out thanks.

code_text
if __name__ == '__main__':
    cerebro.adddata(data1)
    cerebro.adddata(data2)
    cerebro.adddata(data3)

def init(self):
    self.sma = bt.indicators.SimpleMovingAverage( self.datas, 30)
def next(self):
    if self.dataclose > self.sma:
        self.buy()

dear all:
I am a fresher.
I want to test multi stock use same strategy.
how to write the test function?
the following is framework... anybody can share some code ?thanks.

main:#add multi data
cerebro.adddata(data1)
cerebro.adddata(data2)
cerebro.adddata(data3)

def init(self):
self.sma = bt.indicators.SimpleMovingAverage( self.datas, 30)
def next(self):
if self.dataclose > self.sma:
self.buy()
