Buy and sell on same candle

[Misbah Asif 0]

I have to create strategy which will buy and sell on the same candle using stoploss or takeprofit.
I did some code but am not getting the desired output actually am new to backtrader so may be I am missing something.
I am using data from yahoofinance.

def next(self):
    self.starttime = self.data.datetime.time()
    self.new_time = timedelta(hours=self.starttime.hour+5, minutes=self.starttime.minute+30)
    self.curr_time = datetime.strptime(str(self.new_time), '%H:%M:%S').time()
    if not self.position and self.trade <= self.p.total_trades and self.entry_time <= self.curr_time <= self.exit_time:
        if self.rsi > 30 and self.p.position_type in ["long", "both"]:
            self.order = self.buy()
            # exectype=bt.Order.StopLimit ,price=self.data.open[0]
            print("Long buy entry")
            self.have_position = True
        elif self.rsi < 70 and self.p.position_type in ["short", "both"]:
            self.order = self.sell()
            print("Short sell entry")
            self.have_position = True

    elif self.position:
        if self.ord_type == "BUY":
            if self.data.close <= self.stoploss:
                self.order = self.sell()
                self.trade = self.trade+1
                print("Long sell on stoploss")
                self.have_position = False
            elif self.data.close >= self.takeprofit:
                self.order = self.sell()
                self.trade = self.trade + 1
                print("Long sell on takeprofit")
                self.have_position = False
            elif self.curr_time >= self.exit_time:
                self.order = self.sell()
                self.trade = self.trade + 1
                print("Long sell on exit time")
                self.have_position = False

        elif self.ord_type == "SELL":
            if self.data.close >= self.stoploss:
                self.order = self.buy()
                self.trade = self.trade + 1
                print("Short buy on stoploss")
                self.have_position = False

            elif self.data.close <= self.takeprofit:
                self.order = self.buy()
                self.trade = self.trade + 1
                print("Short buy on takeprofit")
                self.have_position = False
