Hi everybody!
I'm trying to create two strategies. 1) Buy at lower band and sell the opened position at upper band. 2) Buy when the close price crossover the upper band and set the SL at the basis line. The stop loss follow the basis line at every new close.
Now. About the first strategy, I've wrote this:
> class DetBB(Strategy): close = data.Close open = data.Open upperband, middleband, lowerband = talib.BBANDS(close, timeperiod=5, nbdevup=2, nbdevdn=2, matype=0) def init(self): close = self.data.Close open = self.data.Open upperband = talib.BBANDS(self.data.Close, timeperiod=20, nbdevup=2, nbdevdn=2, matype=0) lowerband = talib.BBANDS(self.data.Close, timeperiod=20, nbdevup=2, nbdevdn=2, matype=0) def next(self): if crossover(self.open, self.lowerband): tp_teorico = self.upperband[0] if(math.isnan(tp_teorico)): print("not opening") else: self.buy(stop=None,sl=None,limit=None,tp=self.upperband[0]) > bt = Backtest(data, DetBB, cash=10000000, commission=.002, exclusive_orders=True)
Essentially, the backtest is not opening positions, because the value of tp_periodico are always Nan.
About the second strategy, how I can wrote a code that updates my stoploss automatically? Thanks
Wrong forum sorry
