The next() call isn't called.

[T H]

Hi there.
Basically, I want to use 5 seconds dataframe, but I want to use 8 hours dataframe for only the indicator.
But the next() call isn't called when I run the following code.(But The prenext() call is called.)
Am i doing something wrong?

Thank in advance!!

class St(bt.Strategy):
    def __init__(self):
        self.rsi =rsi= bt.indicators.RelativeStrengthIndex(self.datas[1], upperband=80, lowerband=20)
        rsi.plotinfo.plot = False
        # rsi1 = rsi()
        # self.rsi_val = self.data0.close < rsi1.rsi

    def prenext(self):
        print("PRE-NEXT", self.data.close[0], self.rsi+0,
                self.data.datetime.datetime().strftime('%m-%d %H:%M:%S'),
                self.data1.datetime.datetime().strftime('%m-%d %H:%M:%S')
              )

    def next(self):
        print("NEXT", self.data.close[0], self.rsi+0,
                self.data.datetime.datetime().strftime('%m-%d %H:%M:%S'),
                self.data1.datetime.datetime().strftime('%m-%d %H:%M:%S')
              )
        
def runstrategy():
    # Create a cerebro
    cerebro = bt.Cerebro()

    storekwargs = dict(
        token="xxx",
        account="xxx",
        practice=False
    )

    store = StoreCls(**storekwargs)

    DataFactory = store.getdata
    datakwargs = dict(
        timeframe=3, compression=5,
        qcheck=0.5,
        historical=False,
        fromdate=datetime.datetime(2020, 5, 1, 0, 0),
        todate=datetime.datetime(2020, 5, 2, 0, 0),
        bidask=None,
        useask=None,
        backfill_start=True,
        backfill=True,
        tz='Asia/Tokyo'
    )

    data0 = DataFactory(dataname="USD_JPY", **datakwargs)
    data1 = cerebro.resampledata(data0, timeframe=bt.TimeFrame.Seconds, compression=5)
    data2 = cerebro.replaydata(data1, timeframe=bt.TimeFrame.Minutes, compression=480)

    # Add the strategy
    cerebro.addstrategy(St)

    # cerebro.run(exactbars=args.exactbars, stdstats=False, runonce=False,quicknotify=True)
    cerebro.run(exactbars=args.exactbars)
 
    print('Final Portfolio Value: %.2f' % cerebro.broker.getvalue())
    plt.rcParams['axes.unicode_minus']=False
    plt.rcParams['figure.figsize']=[18, 16]
    plt.rcParams['figure.dpi']=200
    plt.rcParams['figure.facecolor']='w'
    plt.rcParams['figure.edgecolor']='k'
    cerebro.plot(iplot=False, style="candle")

runstrategy()
