Just do nothing...........it has the same effect but is cheaper.

What is your logic to open Long and Short order ?

You can try use EA template to create simple logic EA.

    How to create a EA that can open a long and short trade simultaneously?

First your broker have to support hedging. Here's a dumb simple ea code where is actually no logic built but you can see how the open buy and open sell are formulated:

#define MAGIC 1234
#define IDENT 'mo_bidir_v0_1'
 
extern double lots = 1;
extern double stop_loss = 80; // (8 pips) optimise 50-2000
extern double take_profit = 750; // (75 pips) optimise 50-2000
 
int last_bar = 0;
 //**************below this line you see the op_buy & sell WARNING there is no trading logic in this so you have to make it
// **************othervise pure coin toss
int start(){
   if (last_bar == Bars) return(0);
   last_bar = Bars;
   if (OrdersTotal() == 0){
         OrderSend(Symbol(), OP_BUY, lots ,Ask, 3, Ask - stop_loss * Point, Bid + take_profit * Point, IDENT, MAGIC, 0, Blue);
         OrderSend(Symbol(), OP_SELL, lots ,Bid, 3, Bid + stop_loss * Point, Ask - take_profit * Point, IDENT, MAGIC, 0, Red);
   }
   return(0);
}

looks like viper got it covered
