Help using OrderProfit() in MT4

[StevePams]

Hi, I wrote an EA which can trade 1 to 3 Trades at a time on the same currency pair.

The code snippet below seems to calculate the Open Order profits okay but on close they are out by a few percent.

If I run one trade it is accurate.

Can anyone look at the code below and offer any advice?

for( tradeCount=0; tradeCount < OrdersTotal(); tradeCount++ )

{

if(!OrderSelect(tradeCount,SELECT_BY_POS))continue ;

if(OrderType()==OP_BUY&&OrderSymbol()==Symbol() && OrderMagicNumber()==MagicNumber01)TradeProfit01 = OrderProfit() + OrderCommission() + OrderSwap();

if(OrderType()==OP_BUY&&OrderSymbol()==Symbol() && OrderMagicNumber()==MagicNumber02)TradeProfit02 = OrderProfit() + OrderCommission() + OrderSwap();

if(OrderType()==OP_BUY&&OrderSymbol()==Symbol() && OrderMagicNumber()==MagicNumber03)TradeProfit03 = OrderProfit() + OrderCommission() + OrderSwap();

if(OrderType()==OP_SELL&&OrderSymbol()==Symbol() && OrderMagicNumber()==MagicNumber01)TradeProfit01 = OrderProfit() + OrderCommission() + OrderSwap();

if(OrderType()==OP_SELL&&OrderSymbol()==Symbol() && OrderMagicNumber()==MagicNumber02)TradeProfit02 = OrderProfit() + OrderCommission() + OrderSwap();

if(OrderType()==OP_SELL&&OrderSymbol()==Symbol() && OrderMagicNumber()==MagicNumber03)TradeProfit03 = OrderProfit() + OrderCommission() + OrderSwap();

}

I would like to be able to read the Profit displayed in the MT4 Account History and display it in an Alert().

Many thanks.
