extern double Price_Target=0.0;     //The Price at which you want to delete all Pending Orders.
extern string Profit_Target= "ENTER ABOVE THE PRICE YOU TARGET";
                                          
double vbid= MarketInfo("Symbol",MODE_BID);
double vask= MarketInfo("Symbol",MODE_ASK);
                                             
int Slippage=5;
int i;

Check you if statements, it should be "==" not "=".  Declare vask and vbid within start statement and remove ().  
Your error was   '{' - unbalanced parentheses.
That mean if you have opened  parentheses  '{', then it must be always closed '}'
And maybe some other little mistakes.
Try this:
int start()
  {
   if(Ask==Price_Target || Bid==Price_Target)
      {
        for(int i=OrdersTotal()-1;i>=0;i--)
           {
             if(!OrderSelect(i, SELECT_BY_POS)) continue;         
             //---    
             bool result = false;     
             if(OrderType()>1 && OrderSymbol()==Symbol()) result = OrderDelete( OrderTicket() ); 
             //---
             if(!result) Sleep(0);
           }
        Print ("Account Price Reached. All Pending Order Have Been Deleted");   
      } 
   
   Comment("Balance: ",AccountBalance(),", Account Equity: ",AccountEquity(),", Account Profit: ",AccountProfit(),
           "\nMy Account Profit Target: ",Price_Target);   
 
   return(0);
  }
But in this case it also probably will not ever trigger. Because Ask can jump over Price_Target and never will equal to it.
So you must to check in such way:

if((iOpen(NULL,PERIOD_M1,0)<=Price_Target && Ask >= Price_Target)
|| (iOpen(NULL,PERIOD_M1,0)>=Price_Target && Bid <= Price_Target)) 
   {
      .... delete pending
   }

Hi Lazar,

Thank you for guiding. Ok i understand about the need to have "<" or ">". Will try it out...

Is this part still ok or it is wrong too?
double vbid= MarketInfo("Symbol",MODE_BID);
double vask= MarketInfo("Symbol",MODE_ASK);

You can always check anything you need.

Just make data visible for you.

For example you can use Print();

int OnInit()
  {
//---
   Print("Correct = "+ MarketInfo(Symbol(),MODE_BID));
   Print("Wrong = "  + MarketInfo("Symbol",MODE_BID));
//---
   return(INIT_SUCCEEDED);
  }
Then go to the 'Experts' and check it.
You will see:
