Help! - How to not place new order too closed to already opened price?

[Chee Chua]

How do I check through all already opened price?

I tried the following, but does not work.

if (condition).....

for(bcnt=btotal-1; bcnt >= 0; bcnt--)
{
OrderSelect(bcnt, SELECT_BY_POS, MODE_TRADES);
if(OrderType()<=OP_SELL && OrderSymbol()==Symbol())
{
if(OrderType()==OP_BUY)
{

if( (Ask > OrderOpenPrice() + (Point*OrderDist)) || (Ask < OrderOpenPrice() - (Point*OrderDist)) )

{

Buy();

......

here.

bool IsNearPreviousTrade(string _symbol, int order_type, double price=0, double range_in_points=100)
{      
   double range = range_in_points*Point;      
   
   if(price==0)
      price=Ask;
      
   for(int i=OrdersTotal()-1;i>=0;i--)    
   {
      if(OrderSelect(i,SELECT_BY_POS,MODE_TRADES)==false) 
         continue;      
      if(OrderSymbol()!=_symbol) {         
         continue;
      }   
         
      if(order_type==OrderType())               
         if(MathAbs(price-OrderOpenPrice())<range)
            return(true);         
    }              
    return(false);
}


// how to use it...
int start()
{
   if(_buy_condition_)
      if(!IsNearPreviousTrade(Symbol(), OP_BUY, Ask, 50))
         OrderSend(....);       
   ....
}
