Checking the correctness of the code

I would like to ask experienced programmers to tell me what is written incorrectly.
Now I will describe first how everything should actually work:
  





1) Waiting for the candle to close:
1.1) If it closed and we determined that the candle is bullish (bearish), we check 1.2
1.2) Calculate the size of the candle
1.3) Open 2 trades (1 buy,1 sell) if the candle size is equal to the specified range specified in the input parameters. (If the candle is bearish, we open a buy at 0.03 sell at 0.01, for a bullish candle, the opposite is true)
2) The logic of opening the following positions ( taking into account the fact that the candle was bearish) 
2.1) Open trades buy_1 at 0.03
                             sell_1 by 0.01
2.2) If the buy stop loss trade is closed, we open another buy_2 trade with a double lot from the initial volume and 1 sell_2 trade with a double volume
2.3) If the sell is closed by stop loss, we do not do anything, we wait for the sell to close
2.3) If buy_2 closed on stop loss then open sell_3 volume = (buy_1+buy_2+sell_1+sell_2)
2.4) We do not take into account the closing of the stop loss, when the stop loss leads to a positive result because the trailing stop was moved 
2.5) When closing any trade on takeprofit then do nothing waiting for the signal
I will attach parts of the code below .
