Good people, can you give us some advice? When testing an EA, trades don't open in log error 3: Wrong parameters. What have I done wrong with the custom functions?

              ticket=OrderSend(Symbol(),OP_SELLSTOP,Lots,Prices_install(),3,0,0,NULL,MAGICNUMBER,0,clrGreen);
               if(ticket>0)//проверка открытия позиции
                 {
                  if(OrderSelect(ticket,SELECT_BY_TICKET,MODE_TRADES))
                     Print("SELL ордер открыт:",OrderOpenPrice());
                 }
               else
                  Print("Ошибка открытия ордера SELL:",GetLastError());
              }
            return;
           }
        }

Good afternoon help on parabolic please! I want to make logic with the Expert Advisor as shown on the picture:

I write the code like this:

ParSar_0 = iSAR(NULL, time1_method, parsar_Step, parsar_Maximum, 0);
ParSar_1 = iSAR(NULL, time1_method, parsar_Step, parsar_Maximum, 1);

     if(ParSar_0 < Bid && ParSar_1 > Bid)
     {
         TP = NormalizeDouble(Ask + takeprofit * _Point, _Digits);
         ticket = OpenOrder(_Symbol, OP_BUY, lot, Ask, slippage, 0, TP, comment, Magic, 0, clrGreen); //покупка
     }
     
     if(ParSar_0 > Bid && ParSar_1 < Bid)
     {
         TP = NormalizeDouble(Bid - takeprofit * _Point, _Digits);
         ticket = OpenOrder(_Symbol, OP_SELL, lot, Bid, slippage, 0, TP, comment, Magic, 0, clrRed); //продажа
     }
     } 

See if I've made any mistakes, because it's crashing ..... Thanks a lot!

What are the nuances of using loops in making trading decisions by the Expert Advisor? Roughly speaking, if there are 20 levels of support/resistance, will the EA work correctly if we check all levels using for ? Or is it better to take the nearest ones and do it through if?

Please advise how to make it so that on mt4/5 bars would not show openings. Theonly thing it showsis the close of the bar.

Can you tell me how to connect the Statemnt charts? To display a graph of multicurrency trading. I've seen it somewhere for a long time, but I can't find it
