current profits on the same pair

Hello,

I want to get current profits on positions on the same pair.

#include<Trade\Trade.mqh>

CTrade trade;

void OnTick()

  {

double Profit_1, Profit_2;

double Ask_EURGBP=NormalizeDouble(SymbolInfoDouble("EURGBP", SYMBOL_ASK), _Digits); 

double Bid_EURGBP=NormalizeDouble(SymbolInfoDouble("EURGBP", SYMBOL_BID), _Digits); 

if(PositionsTotal()<2)

{

trade.Buy(0.01,"EURGBP",Ask_EURGBP,NULL,NULL,NULL);

trade.Sell(0.01,"EURGBP",Bid_EURGBP,NULL,NULL,NULL);

}

if(PositionGetInteger(POSITION_TYPE)==POSITION_TYPE_BUY)

if(PositionSelect("EURGBP")){Profit_1=PositionGetDouble(POSITION_PROFIT);}

if(PositionGetInteger(POSITION_TYPE)==POSITION_TYPE_SELL)

if(PositionSelect("EURGBP")){Profit_2=PositionGetDouble(POSITION_PROFIT);}

Comment(Profit_1+"\n"+Profit_2);

  }

Profit_1 works but Profit_2 doesn't work and why ?
