gives pipvalue for a lot traded on specific symbol

1. There are some buy orders are opened and one buy pending order is placed. all orders are in same currency pair. how an EA will select only last opened order to check its stop limits?

2. every opened order was placed at different prices with tp 20. is it possible for ea to to modify all opened orders except the last one, and change their stop limits to the stop limits of last opened order?

EXAMPLE:

Sr    type   price     tp
1     buy    1.23950   1.23750
------------------------------
# buylimit   1.23750   1.23550

//////////////////////////////

1    buy     1.23950   1.23550 // tp modified and now equal to 2nd tp
2    buy     1.23750   1.23550 // 2nd tp
------------------------------
# buylimit   1.23550   1.23350

//////////////////////////////

1    buy     1.23950   1.23350 // tp modified and now equal to 3rd tp
2    buy     1.23750   1.23350 // tp modified and now equal to 3rd tp
3    buy     1.23550   1.23350 // 3rd tp
------------------------------
# buylimit   1.23350   1.23150

Some confusion with...

//Signal Filter
#define XXX   0
#define AAA   1
#define BBB   2

int SignalS = XXX;

if(SignalS & AAA !=0)
OrderSend(NULL, OP_BUY, LotSize, Ask, Slippage, SL, TP, WindowExpertName(), MagicID, 0, Blue);

Old editor accepts the highlighted lines, but new editor gives warning "Expression not boolean"

I tried then...

if(SignalS && AAA !=0)
//or
if(SignalS !=0 & AAA !=0)

Now new editor accepts both, but... which one will work the same like the highlighted line? if both true, then which one should i use? (more convenient?)

PS: Below code is also accepted by new editor...

if((SignalS & AAA) !=0)

New editor accepts all three, but... which one will work the same like the highlighted line? if all true, then which one will be more convenient for me?

1. Don't use a bit mask

   //Signal Filter #define XXX   0 #define AAA   1 #define BBB   2 int SignalS = XXX; if(SignalS & AAA !=0)	enum eSignals = {XXX, AAA, BBB}; eSignals SignalS = XXX; if(SignalS == AAA) Self documenting code.

2. Using a bit mask:

   On build 600+ != has higher precedence than bitwise and, you MUST use (SignalS & AAA) !=0

   On prior builds bitwise and was higher than multiplication

WHRoeder i found your code (select last market order) and added highlighted lines to check its tp price and to set the same tp price on previous orders:

int PositionIndex;    //  <-- this variable is the index used for the loop

int TotalNumberOfOrders;   //  <-- this variable will hold the number of orders currently in the Trade pool
double Ord_TP=0;
TotalNumberOfOrders = OrdersTotal();    // <-- we store the number of Orders in the variable

for(PositionIndex = TotalNumberOfOrders - 1; PositionIndex >= 0 ; PositionIndex --)  //  <-- for loop to loop through all Orders . .   COUNT DOWN TO ZERO !
   {
   if( ! OrderSelect(PositionIndex, SELECT_BY_POS, MODE_TRADES) ) continue;   // <-- if the OrderSelect fails advance the loop to the next PositionIndex
   
   if( OrderMagicNumber() == MagicNo       // <-- does the Order's Magic Number match our EA's magic number ? 
      && OrderSymbol() == Symbol()         // <-- does the Order's Symbol match the Symbol our EA is working on ? 
      && ( OrderType() == OP_BUY           // <-- is the Order a Buy Order ? 
      ||   OrderType() == OP_SELL ) )      // <-- or is it a Sell Order ?
   if(OrderTakeProfit()>0) 
   Ord_TP = OrderTakeProfit(); break;
   if(OrderTakeProfit() == Ord_TP) continue;
    OrderModify(OrderTicket(),0,0,Ord_TP,0,CLR_NONE);
      //if ( ! OrderClose( OrderTicket(), OrderLots(), OrderClosePrice(), Slippage ) )               // <-- try to close the order
         //Print("Order Close failed, order number: ", OrderTicket(), " Error: ", GetLastError() );  // <-- if the Order Close failed print some helpful information 
      
   } //  end of For loop

An extra line...

if(OrderTakeProfit()>0) 
   Ord_TP = OrderTakeProfit(); break;
   if(OrderTakeProfit() == Ord_TP) continue;
   if(OrderTakeProfit() != Ord_TP)
    OrderModify(OrderTicket(),0,0,Ord_TP,0,CLR_NONE);

Please guide, if i am wrong.

(All market+pending orders type is only buy, not sell or only sell, not buy and i want the tp of all market orders to be changed every time, when new market order is opened).

THIS IS REALLY TOUGH FOR ME, BUT I WANT TO DO IT. :(

Your indenting is wrong because you didn't use braces	if(OrderTakeProfit()>0)    Ord_TP = OrderTakeProfit(); break;    if(OrderTakeProfit() == Ord_TP) continue;    if(OrderTakeProfit() != Ord_TP)     OrderModify(OrderTicket(),0,0,Ord_TP,0,CLR_NONE);
What your code actually is	if(OrderTakeProfit()>0)    Ord_TP = OrderTakeProfit(); break; /*NOTREACHED    if(OrderTakeProfit() == Ord_TP) continue;    if(OrderTakeProfit() != Ord_TP)     OrderModify(OrderTicket(),0,0,Ord_TP,0,CLR_NONE); */

Things are getting complicated for me. I think i should write code from start. and i will paste each part of code here. maybe i could understand that better.
