Help with Lot sizing

So I started writing a basic EA with one of those template generating EA builders. I seem to have gotten the premise of the EA template down, however I need a way to make the EA only enter one trade at max. Right now it keeps generating trades and causes the draw down to be rediculous. Here is the trade lot code:

//Check position
bool IsTrade = False;

for (int i = 0; i < Total; i ++) {
OrderSelect(i, SELECT_BY_POS, MODE_TRADES);
if(OrderType() <= OP_SELL && OrderSymbol() == Symbol()) {
IsTrade = True;
if(OrderType() == OP_BUY) {
//Close

//+------------------------------------------------------------------+
//| Signal Begin(Exit Buy) |
//+------------------------------------------------------------------+

if (CloseBuy1_1 >= CloseBuy1_2) Order = SIGNAL_CLOSEBUY;


//+------------------------------------------------------------------+
//| Signal End(Exit Buy) |
//+------------------------------------------------------------------+

if (Order == SIGNAL_CLOSEBUY && ((EachTickMode && !TickCheck) || (!EachTickMode && (Bars != BarCount)))) {
OrderClose(OrderTicket(), OrderLots(), Bid, Slippage, MediumSeaGreen);
if (SignalMail) SendMail("[Signal Alert]", "[" + Symbol() + "] " + DoubleToStr(Bid, Digits) + " Close Buy");
if (!EachTickMode) BarCount = Bars;
IsTrade = False;
continue;
}
//Trailing stop
if(UseTrailingStop && TrailingStop > 0) {
if(Bid - OrderOpenPrice() > Point * TrailingStop) {
if(OrderStopLoss() < Bid - Point * TrailingStop) {
OrderModify(OrderTicket(), OrderOpenPrice(), Bid - Point * TrailingStop, OrderTakeProfit(), 0, MediumSeaGreen);
if (!EachTickMode) BarCount = Bars;
continue;
}
}
}
} else {
//Close

If anyone could help, it would be greatly appreciated.

In the account history, is it entering one trade, then closing it, then entering another trade, then closing it, etc? Or are there multiple trades open at one time?

Multiple Open trades at one time. I want at max 1 trade ever open. It would be nice to have each trade as 2% of the total portfolio, but that might be asking too much.

Can you put up the whole code?

I'm looking specifically for the "IsTrade" variable.
