class LeiDa(bt.Indicator):
lines = ('zhuli', )

def __init__(self):
    self.addminperiod(30)


def next(self):
    dataclose = self.data.get(size=30)
    close_ma = talib.MA(np.array(dataclose), timeperiod=7, matype=0)

    temp = (dataclose[-20:] - close_ma[-20:]) / close_ma[-20:] * 480
    result = talib.EMA(temp, timeperiod=2) * 5

    self.zhuli[0] = result[-1:]

class MyStrategy(bt.Strategy):

def __init__(self):
    self.leida = LeiDa(self.data)
    self.leida.plotinfo.plotmaster = self.data

@run-out Hi ,I just post my code, Can you help me? Why didn't my indicator plot with the main data? Thank you!

your price range is 240+, your indicator shows -1.43. diagram range is set by master, therefore you can't see the indicator. I suggest to show it on the separate plot since this is type of the oscillator.
