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

    {

    if (OrderType()==OP_BUY||OrderType()==OP_SELL)

    {

    if (OrderProfit()<0){(fnewlot=(OrderLots()*2));}

    }    

    else if ( OrderProfit()>0){(fnewlot=Lot_size);}

First off, what does the last order mean? The last opened order? The last closed order? Next you need to sort them programmatically in order to work with them. So for example if you said, "my criteria for 'last order' really means the most recently opened order", then you would need to sort the history pool by OrderOpenTime. Below is an example using the MQL4OrderPool class. BTW, next time you post code, please use the SRC button.

int LotSize(int magic,double start_lot_size)
{
   MQL4OrderPool pool;
   pool.Init(Symbol(),magic,MODE_HISTORY,ORDERS_FILLED,SORT_OPEN_TIME_DESCENDING);
   int losing = 0;
   if(pool.Total()==0)
      return start_lot_size;
   return NormalizeDouble(pool[0].OrderLots() * 2, 2);
}

hey guys, please give me a light,


i'm with a trouble with getting the ordersize that was opened,


my ea works with a "switch" 


if RSI (10) > 70     - i want to use my baselotsize / 2. [ buy case ]

if RSI (10) < 70     - baselotsize;  [ buy case ]


if RSI (10) < 30      -i want to use my baselotsize / 2. [ sell case ]

if RSI (10) > 30      - baselotsize;  [ buy case ]


i use martingale with loose blocks on code. i need to "read" the lotsize after the opening of the first order and store this, how do i do that?
