HI, I want to sell half or a quarter of the initial trade amount for each trade when the current price meets certain conditions. But once I change the initial wallet amount, I get different backtest results. I thought there must be something wrong with the code. The code is wrote based on the documentation's example. But I cannot find more information in the documentation. I would be really grateful for your help!

                            ) -> float | None | tuple[float | None, str | None]:

        if current_rate >= 1*width_candle+last_candle["resistance"]:
            return  -0.5* stake_amount
        if  current_rate <0.98*last_candle["resistance"]:
