Move  "const int magicNumber = OrderMagicNumber();" within the "if(OrderSelect(i,SELECT_BY_POS, MODE_HISTORY)==true)".

Like that:

   for(int i=0;i<total;i++)
     {
      if(OrderSelect(i,SELECT_BY_POS, MODE_HISTORY)==true)
        {
         const int magicNumber = OrderMagicNumber();
         if(OrderSymbol()==Symbol() && (1000 * Base_Magic_Number <= magicNumber && magicNumber < (1000 * Base_Magic_Number + 100)))

Yes nice it works. Thank you..

Like that:

   for(int i=0;i<total;i++)
     {
      if(OrderSelect(i,SELECT_BY_POS, MODE_HISTORY)==true)
        {
         const int magicNumber = OrderMagicNumber();
         if(OrderSymbol()==Symbol() && (1000 * Base_Magic_Number <= magicNumber && magicNumber < (1000 * Base_Magic_Number + 100)))

You can check if a position magic number is from that portfolio expert by this way:

const int magicNumber = OrderMagicNumber();
if (1000 * Base_Magic_Number <= magicNumber && magicNumber < (1000 * Base_Magic_Number + 100))
 {
  // Do the things here
 }

I tried it out put your example like this in code.

double Total_History_Profit()
  {
   const int magicNumber = OrderMagicNumber();
   double totalhistoryprofit=0;
   int total=OrdersHistoryTotal();
   for(int i=0;i<total;i++)
     {
      if(OrderSelect(i,SELECT_BY_POS, MODE_HISTORY)==true)
        {
         if (1000 * Base_Magic_Number <= magicNumber && magicNumber < (1000 * Base_Magic_Number + 100))
         if(OrderSymbol()==Symbol())
         if(OrderType()==OP_SELL || OrderType()==OP_BUY)
           {
            totalhistoryprofit+= OrderSwap()+OrderProfit();
           }
        }
     }
   return(totalhistoryprofit);
  }  

also like this isnt working well.

double Total_History_Profit()
  {
   const int magicNumber = OrderMagicNumber();
   double totalhistoryprofit=0;
   int total=OrdersHistoryTotal();
   for(int i=0;i<total;i++)
     {
      if(OrderSelect(i,SELECT_BY_POS, MODE_HISTORY)==true)
        {
         if(OrderSymbol()==Symbol() && (1000 * Base_Magic_Number <= magicNumber && magicNumber < (1000 * Base_Magic_Number + 100)))
         if(OrderType()==OP_SELL || OrderType()==OP_BUY)
           {
            totalhistoryprofit+= OrderSwap()+OrderProfit();
           }
        }
     }
   return(totalhistoryprofit);
  }  

But i get the complete history Total Profit not only from the magicnumbers.
What about when i use portfolio 4 times. One Basic Magicnumber 400...one 401..one 402.. So if the code runs on basic numver 402 and the code is

(1000 * Base_Magic_Number <= magicNumber && magicNumber < (1000 * Base_Magic_Number + 100)

so when an has a smaller basenumber it will count all together.

i have tried that but dont work

         if(OrderSymbol()==Symbol()&& OrderMagicNumber()== GetMagicNumber());

A Portfolio Expert opens positions with different Magic numbers for each included strategy.

We are currently developing a tool in EA Studio that will be able to calculate the stats form a particular date. It will help you for that case.

On the other hand, if you need to calculate the profit in the expert, you have to take into account all used magic numbers.

The positions' Magic Number calculation is:

int GetMagicNumber(int strategyIndex)
  {
   int magic=1000*Base_Magic_Number+strategyIndex;
   return (magic);
  }

The strategyIndex is from 0 to the count of the strategies - 1.

..

Now I think that probably adding trading info in the Portfolio Expert is a good idea. It may be like in the FSB Pro's experts and to plot on the chart something like:
Total strategies: 32
Long  positions count: 11, lots: 0.11, profit: 333
Short positions count: 03, lots: 0.03, profit: -24

yes i saw that this calculation. but when i try to implement it in my functions it gives me errors..
something lik GetMagicNumber() dont work on my process

we have to put the calculated magicnumber as global variable than it might be work.. but i dont know how to solve this..

how can i get the total Profit of an Portfolio EA?

On normal Eas this kind of code is working well.

double Total_History_Profit()
  {
   double totalhistoryprofit=0;
   int total=OrdersHistoryTotal();
   for(int i=0;i<total;i++)
     {
      if(OrderSelect(i,SELECT_BY_POS, MODE_HISTORY)==true)
        {
         if(OrderSymbol()==Symbol()&& OrderMagicNumber()==Magic_Number)
         if(OrderType()==OP_SELL || OrderType()==OP_BUY)
           {
            totalhistoryprofit+= OrderSwap()+OrderProfit();
           }
        }
     }
   return(totalhistoryprofit);
  }  

But cause Portfolio have different magicnumbers.. What did i have to put in this line instead of Magic_Number?

         if(OrderSymbol()==Symbol()&& OrderMagicNumber()==Magic_Number)
