Search in the codebase for some MT4 Stochastic EA and study it. Your EA needs at least a Magic number (unique identifier) to count the number of open orders correctly.

If you want to limit the number of open trades, test against a maximum value like MaxBuys or so:

input int InpMaxBuys=1; // max open buy orders

and

if(k0 > d0 && k1 < d1 && MyOpenBuys<InpMaxBuys)

If you want to have a difference of X pips between the orders you need to find the open order which is nearest to the Ask.

You can combine it with the loop that counts your open orders.

int MyOpenBuys(double &nearest)
  {
   int count=0;
   nearest=999999;

   for(int i=OrdersTotal()-1; i>=0; i--)
     {
      if(OrderSelect(i,SELECT_BY_POS) && OrderSymbol()==_Symbol && OrderMagicNumber()==MagicID)
        {
         if(OrderType()==OP_BUY)
           {
            count++;
            if(MathAbs(OrderOpenPrice()-Ask)<MathAbs(nearest-Ask)) nearest=OrderOpenPrice();
           }
        }
     }
   return count;
  }

and

double nearestBuy;
if(k0 > d0 && k1 < d1 && MyOpenBuys(nearestBuy)<InpMaxBuys && Ask-nearestBuy>=distance*RealPipPoint(_Symbol))
That's Work Thankx Mate 
Appreciated
