How to apply 3 possible sell conditions with different position sizes in backtesting py

Question

I am trying to make a system in python with 1 precise buy condition and 3 possible sell conditions. However, I can't make sell conditions work as I would like to.

I use simple moving averages with 8 and 50 periods AND 10% stop loss for buying. I don't face with any problem there. System buys when they crossover.

My sell conditions are basically occurs when moving average 50 crosses moving average 8. However, I would like to sell different position sizes if the signal occurs when the price is below the entry price or not.

I mean, assume that I bought at the price 50 (when mov8 and 50 crosses)

When mov 50 and mov8 crosses (which is sell signal), I would like to check if the price is below the entry price or not.

If the price is below than the entry price when the selling signal occurs, I would like to close my all position ( first possible sell condition). However, if the price is above than the entry price, I would like to sell only %30 of my position, and keep the trade until mov50 and mov8 crosses next time ( second possible sell condition). If mov50 and mov8 crosses again, then I would like to close my rest of position, which is 70%, ( third possible sell condition).

But as you can see on my trades that I backtested, my second and third conditions don't work well.

Firstly, I defined moving averages and stop loss here,: class Z(Strategy): day1 = 8 day2 = 50
sprice=0.1

def init(self):

    self.signal1 = self.I(SIGNAL)
    self.ma1 = self.I(talib.SMA, self.data.Close, self.day1)
    self.ma2 = self.I(talib.SMA, self.data.Close, self.day2)      
    self.long_position1 = False
    self.long_position2 = False
    self.long_position3 = False
    self.long_position4 = False
    self.entry_price = 0 

Here is my buy condition:

def next(self):         
        
    if not self.position:
        
        if crossover(self.ma1, self.ma2):
           
            sl1 = self.data.Close[-1] - self.data.Close[-1] *self.sprice
            self.buy(sl=sl1)
            self.entry_price = self.data.Close[-1]

Here is my first sell condition, which closes all position:

  if self.position:
        
            if crossover(self.ma2, self.ma1):



                if (self.data.Close <= self.entry_price):  
                        
                        self.position.close()
                       

And here is where I would like to sell 30% of my position size. I used here boolean variables so I aimed that if this happens, it can only go to my third sell condition. :

                else:
                        self.sell(size=0.3)
                        self.long_position1 = False
                        self.long_position2 = True
                        self.long_position3 = True
                        self.long_position4 = False


    
        
            if not self.long_position1 and self.long_position2 and self.long_position3 and not self.long_position4: 
                    if crossover(self.ma2, self.ma1) :
                        self.position.close()
                        self.long_position1 = False
                        self.long_position2 = False
                        self.long_position3 = False
                        self.long_position4 = False

a=Backtest(K,Z,cash=10000,trade_on_close=True,margin=0.6,exclusive_orders=True)

Here is my trades, When it sells %30 of the position, It keeps sell somehow. But It should happens only once and then go through the third condition.
