Multiple trades Trailing

[[Deleted]]

I use the code below to find breakeven of all the trades I have a point I close all of them at 0, my question is how can I trail?

string eq;
      string Sym[];
      double Equity[];
      double Lots[];
      double sum             = 0;
      string level0          = "";
      ArrayResize(Sym,0);
      ArrayResize(Equity,0);
      ArrayResize(Lots,0);
     
      for(int i = 0; i < OrdersTotal(); i++)
         {
              if(!OrderSelect(i, SELECT_BY_POS, MODE_TRADES))continue;
              if(OrderMagicNumber() != Magic)continue;
              if(OrderType() != OP_BUY && OrderType() != OP_SELL) continue;
              
              bool found   = false;
              int size     = ArraySize(Sym);
              int pind     = 0;
              
              for(int k = 0; k < size; k++)
                 {
                   if(Sym[k] == OrderSymbol()) 
                      {
                           Equity[k] += OrderProfit() + OrderCommission() + OrderSwap();
                           if(OrderType() == OP_BUY) Lots[k] += OrderLots();
                           if(OrderType() == OP_SELL) Lots[k] -= OrderLots();
                           found = true;
                           pind  = k;
                           break;
                      }
                 }
             
              if (found) continue;
             
              int ind = ArraySize(Sym);
              ArrayResize(Sym, ind + 1);
              Sym[ind] = OrderSymbol();
              
              ArrayResize(Equity, ind + 1);
              Equity[ind] = OrderProfit() + OrderCommission() + OrderSwap();
              
              ArrayResize(Lots, ind + 1);
              if(OrderType() == OP_BUY)Lots[pind]  = OrderLots();
              if(OrderType() == OP_SELL)Lots[pind] = -OrderLots();
         }
      
      for(int i = 0; i < ArraySize(Sym); i++)
         {
           if(Lots[i] == 0)level0 = "Lock";
           else 
              {
                int    dig   = (int) MarketInfo(Sym[i],MODE_DIGITS);
                double point = MarketInfo(Sym[i],MODE_POINT);
                
                double COP   = Lots[i] * MarketInfo(Sym[i],MODE_TICKVALUE);
                double val   = MarketInfo(Sym[i],MODE_BID) - point * Equity[i] / COP;
                level0       = DoubleToStr(val, dig);
              }
           sum += Equity[i];
         }

After selecting the trade, just after this, you can check if the conditions are met to trail.

if(OrderType() != OP_BUY && OrderType() != OP_SELL) continue;

This is mql4, it should be in mql4 section below.

Okay, thanks for the reply. the code finds the break-even price if I can find the price level where all trades can be x  amount example the price level where all trades are $5
