Help me grid code

see picture and 

i wirte code :

if(Ask!=FindOrderOpenPriceByType(MagicNumberBuy,OP_BUY) && (Ask-(GridStep*Point)>=FindOrderOpenPriceByType(MagicNumberBuy,OP_BUY) &&

   Ask+(GridStep*Point)<=FindOrderOpenPriceByType(MagicNumberBuy,OP_BUY)))
   int buy4=OrderSend(Symbol(),OP_BUY,MinLots,Ask,0,0,0,comment,MagicNumberBuy,0,clrGreen); 



//--------------------------------------------------------------------------------------

double FindOrderOpenPriceByType(int magic,int input_type)

{  

  for(int func_i=OrdersTotal()-1;func_i>=0;func_i--)

   {

      if(OrderSelect(func_i,SELECT_BY_POS,MODE_TRADES) && OrderSymbol()==Symbol() && OrderType()==input_type && OrderMagicNumber()==magic)

      return OrderOpenPrice();

   }



return -1;

}

//----------------------------------------------------------------------

ea not working.

thank you.

 

Up trend:

You must look for nearest open order price below Ask. If distance is greater grid step, open buy order.

Down trend:

You must look for nearest open order price above Ask. If distance is greater grid step, open buy order.

double nearestBuyAboveAsk=FindNearestOpenPriceAbove(Ask,MagicNumberBuy,OP_BUY);
double nearestBuyBelowAsk=FindNearestOpenPriceBelow(Ask,MagicNumberBuy,OP_BUY);

if(nearestBuyAboveAsk==-1 || nearestBuyBelowAsk==-1) {
   // to do: what if not exist?
}
else if(Ask-(GridStep*Point)>=nearestBuyBelowAsk && Ask+(GridStep*Point)<=nearestBuyAboveAsk) {
   int buy4=OrderSend(Symbol(),OP_BUY,MinLots,Ask,0,0,0,comment,MagicNumberBuy,0,clrGreen); 
   ...
}

//--------------------------------------------------------------------------------------

double FindNearestOpenPriceAbove(double price,int magic,int ordertype) {
  double min=99999;
  double openprice=-1;

  for(int i=OrdersTotal()-1;i>=0;i--) {
     if(OrderSelect(i,SELECT_BY_POS,MODE_TRADES) && OrderSymbol()==Symbol() && OrderType()==ordertype && OrderMagicNumber()==magic) {
        double dist=OrderOpenPrice()-price;
        if(dist>=0 && min>dist) { min=dist; openprice=OrderOpenPrice(); }
     }
  }
  return openprice;
}

double FindNearestOpenPriceBelow(double price,int magic,int ordertype) {
  double min=99999;
  double openprice=-1;

  for(int i=OrdersTotal()-1;i>=0;i--) {
     if(OrderSelect(i,SELECT_BY_POS,MODE_TRADES) && OrderSymbol()==Symbol() && OrderType()==ordertype && OrderMagicNumber()==magic) {
        double dist=price-OrderOpenPrice();
        if(dist>=0 && min>dist) { min=dist; openprice=OrderOpenPrice(); }
     }
  }
  return openprice;
}

ea working

thank you.

 

For short grid you need this other way round:

double nearestSellAboveBid=FindNearestOpenPriceAbove(Bid,MagicNumberSell,OP_SELL);
double nearestSellBelowBid=FindNearestOpenPriceBelow(Bid,MagicNumberSell,OP_SELL);
  
double nearestBuyAboveAsk=FindNearestOpenPriceAbove(Ask,MagicNumberBuy,OP_BUY);
double nearestBuyBelowAsk=FindNearestOpenPriceBelow(Ask,MagicNumberBuy,OP_BUY);

if(nearestBuyAboveAsk==-1 || nearestBuyBelowAsk==-1) {
  nearestBuyAboveAsk=FindNearestOpenPriceAbove(Ask,MagicNumberBuy,OP_BUY);
  nearestBuyBelowAsk=FindNearestOpenPriceBelow(Ask,MagicNumberBuy,OP_BUY);
}
 else if(Ask-(GridStep*Point)>=nearestBuyBelowAsk && Ask+(GridStep*Point)<=nearestBuyAboveAsk){ 
   int buy4=OrderSend(Symbol(),OP_BUY,MinLots,Ask,0,0,0,comment,MagicNumberBuy,0,clrGreen); 
 }  


double nearestSellAboveBid=FindNearestOpenPriceAbove(Bid,MagicNumberSell,OP_SELL);
double nearestSellBelowBid=FindNearestOpenPriceBelow(Bid,MagicNumberSell,OP_SELL);

if(nearestSellAboveBid==-1 || nearestSellBelowBid==-1) {
   nearestSellAboveBid=FindNearestOpenPriceAbove(Bid,MagicNumberSell,OP_SELL);
   nearestSellBelowBid=FindNearestOpenPriceBelow(Bid,MagicNumberSell,OP_SELL);
}
else if(Bid-(GridStep*Point)>=nearestSellBelowBid && Bid+(GridStep*Point)<=nearestSellAboveBid) {
   int sell4=OrderSend(Symbol(),OP_SELL,MinLots,Bid,0,0,0,comment,MagicNumberSell,0,clrRed); 
  }
