      Hi, Very frequently I struggled with float division by zero error. It goes away only after removing multiple tickers data. I went thru existing threads and suggested solutions to supply ```
      safediv or safezero

      however this parameter is not valid for all indicators. Appreciate any help! Attached is the code

      class Strategy(bt.Strategy):
      params = dict(
      selcperc=0.15, # percentage of stocks to select from the universe
      rperiod=1, # period for the returns calculation, default 1 period
      vperiod=252, # lookback period for volatility - default 36 periods
      mperiod=126, # lookback period for momentum - default 12 periods
      reserve=0.05, # 5% reserve capital
      when=bt.timer.SESSION_START,
      timer=True,
      monthdays=[1],
      monthcarry=True
      )

      def log(self, arg):
        print('{} {}'.format(self.datetime.date(), arg))   

def __init__(self):

      bt.indicators.Stochastic(self.datas[0], safediv=True)

          # calculate 1st the amount of stocks that will be selected
    self.selnum = int(len(self.datas) * self.p.selcperc)

    # allocation perc per stock
    # reserve kept to make sure orders are not rejected due to
    # margin. Prices are calculated when known (close), but orders can only
    # be executed next day (opening price). Price can gap upwards
    self.perctarget = (1.0 - self.p.reserve) / self.selnum

    # returns, volatilities and momentums
    rs = [bt.ind.PctChange(d, period=self.p.rperiod) for d in self.datas] # safediv safezero
    vs = [bt.ind.StdDev(ret, period=self.p.vperiod) for ret in rs]
    ms = [bt.ind.ROC(d, period=self.p.mperiod) for d in self.datas]

    # simple rank formula: (momentum * net payout) / volatility
    # the highest ranked: low vol, large momentum, large payout

      self.ranks = {d: d.npy * m / v for d, v, m in zip(self.datas, vs, ms)}

          self.ranks = {d: m / v for d, v, m in zip(self.datas, vs, ms)}

    self.add_timer(

        reverse=True,  # highest ranked 1st ... please
    )

    # put top ranked in dict with data as key to test for presence
    rtop = dict(ranks[:self.selnum])


    # For logging purposes of stocks leaving the portfolio
    rbot = dict(ranks[self.selnum:])

    # prepare quick lookup list of stocks currently holding a position
    posdata = [d for d, pos in self.getpositions().items() if pos]

    # remove those no longer top ranked
    # do this first to issue sell orders and free cash
    for d in (d for d in posdata if d not in rtop):

          Hi Sabir, bt.DivByZero is what you're looking for. Here's an example where I use it

          class WeighInverseVol(bt.Strategy):
    params = (
        ('period', 30),
    )

    def __init__(self):
        rs = [bt.ind.PctChange(d, period=1) for d in self.datas]
        vs = [bt.ind.StdDev(ret, period=self.params.period) for ret in rs]
        inv = [bt.DivByZero(bt.LineNum(1), v) for v in vs]
        invsum = bt.LineNum(0)
        for inv_ in inv:
            invsum += inv_
        # self.weights is an array of asset allocation weights
        # one weight per asset in self.datas
        self.weights = [inv_ / invsum for inv_ in inv]

          Here's the source code for bt.DivByZero: https://github.com/mementum/backtrader/blob/master/backtrader/functions.py#L43

            Hello Ronny, Thanks a ton!! it worked.
            If I may share another issue faced by me is monthly rebalancing. The workaround I do to resample data for monthly frequency and run the backtest. I tried below code to trigger monthly rebalancing on daily price series however looking at the log I understand it's not working. Appreciate help/ pointers

            class Strategy(bt.Strategy):
    params = dict(
        selcperc=0.15,  # percentage of stocks to select from the universe
        rperiod=1,  # period for the returns calculation, default 1 period

        mperiod=126,  # lookback period for momentum - default 12 periods
        reserve=0.05,  # 5% reserve capital

              Hello Ronny, Thanks a ton!! it worked.
              If I may share another issue faced by me is monthly rebalancing. The workaround I do to resample data for monthly frequency and run the backtest. I tried below code to trigger monthly rebalancing on daily price series however looking at the log I understand it's not working. Appreciate help/ pointers

              class Strategy(bt.Strategy):
    params = dict(
        selcperc=0.15,  # percentage of stocks to select from the universe
        rperiod=1,  # period for the returns calculation, default 1 period
        vperiod=126,  # lookback period for volatility - default 36 periods
        mperiod=126,  # lookback period for momentum - default 12 periods
        reserve=0.05,  # 5% reserve capital
        when=bt.timer.SESSION_END, #SESSION_START,

        self.selnum = int(len(self.datas) * self.p.selcperc)

        # allocation perc per stock
        # reserve kept to make sure orders are not rejected due to
        # margin. Prices are calculated when known (close), but orders can only
        # be executed next day (opening price). Price can gap upwards
        self.perctarget = (1.0 - self.p.reserve) / self.selnum
