Sell and Buy limits are not being respected

[MrPotatoHead-Dev]

Here is the code for a strategy I have.

df = df[-70:]
class PatreonBlock(Strategy):
    initsize = 0.99
    mysize = initsize

    def init(self):
        super().init()
        self.signal1 = self.I(SIGNAL)

    def next(self):
        super().next()
        stoploss = self.data.SL[-1]
        range_High = self.data.ons_High[-1]
        range_Low = self.data.ons_Low[-1]
        entry = self.data.entry[-1]
        cc_close = self.data.Close[-1]

        if self.data.signal is not None:
            if self.data.signal == 1.0 and stoploss > cc_close:
                print(entry, stoploss, range_Low, self.data.time[-1])
                print()
                self.sell( tp = range_Low, sl=stoploss+10, size =1)
            elif self.data.signal == 2.0:
                tp_price = range_High
                self.buy(tp = range_Low, sl=stoploss-10)
                
             

Ive plotted the signals and they are showing up where they are but when I go to use backtesting the positions arent being opened. I have tried on VS code and on Colab. both with limits, and without. Im stumped.

Any help would be much appreciated.
Ps I know its a bit messy as I was moving things around trying to get it to work. With the lookback of the last 70 candles I should have multiple short positions opened.
Its using data from US100
