How do I specify OrderopenPrice for two separate pairs?

I have an EA to open buy for two pairs simultaneously. Then I want to close when either difference or sum of the profit in pips is > TakeProfit. the only problem is I don't know how to get OrderOpenPrice for both currencies at the same time. Any insight would be appreciated

extern string Symbol_1 = "EURUSDm";
extern string Symbol_2 = "USDCHFm";

for(cnt = OrdersTotal(); cnt >= 0; cnt--)
{
OrderSelect(cnt, SELECT_BY_POS, MODE_TRADES);
if(OrderSymbol()==Symbol())
{
if((MarketInfo(Symbol_1,MODE_BID)-OrderOpenPrice()) + (MarketInfo(Symbol_2,MODE_BID)-OrderOpenPrice())>TakeProfit*Point ||
(MarketInfo(Symbol_1,MODE_BID)-OrderOpenPrice()) - (MarketInfo(Symbol_2,MODE_BID)-OrderOpenPrice())>TakeProfit*Point ||
(MarketInfo(Symbol_2,MODE_BID)-OrderOpenPrice()) - (MarketInfo(Symbol_1,MODE_BID)-OrderOpenPrice())>TakeProfit*Point)
{
OrderClose(OrderTicket(),OrderLots(),Bid,3,Violet);
return(0);
}
}
}
return(0);

are these the only two pairs you are going to be trading with the ea?? If so just subtract the account balance from the account equity and when they hit your profit target, close both orders.

Just an idea, not sure if you plan on running it on multiple pairs.

would something like that work for 0.7% of profit?

extern double TakeProfit = 0.07;

for(cnt = OrdersTotal(); cnt >= 0; cnt--)
{
OrderSelect(cnt, SELECT_BY_POS, MODE_TRADES);
if(OrderSymbol()==Symbol())
{
if((AccountEquity()-AccountBalance())/100>TakeProfit)
{
OrderClose(OrderTicket(),OrderLots(),Bid,3,Violet);
return(0);
}
}
}
return(0);
