I'm writing an EA to alternate buy and sell orders. I can code to alternate orders when there is a history, but not from first start of EA. This is the base simple code. How do I code to alternate orders?

if(OrderType()==OP_SELL) Buy=true;
 
if(OrderType()==OP_BUY) Sell=true;

Thanks,
Wackena

Fractal Analysis of Joint Currency Movements

How independent are currency quotes? Are their movements coordinated or does the movement of one currency suggest nothing of the movement of another? The article describes an effort to tackle this issue using nonlinear dynamics and fractal geometry methods.

Stringo,
I've been using your code suggestion, but that is not my problem. The problem is when the EA starts and there are no open orders, OrderType() then would have no data. After first order, then above code works great. It is just how do I get by that first order. Right now, I start EA with a different code just to get first order and then modify code as above. Then EA runs as intended.

Stringo,

In my EA there are other signals needed to trigger order. Those signals along with code below now works OK.

Thanks for your helpful idea.

Wackena

int hstTotal=HistoryTotal();
Buy=false;
Sell=false;
 
if(hstTotal==0 || OrderType()==OP_SELL) Buy=true;
 
if(hstTotal==0 || OrderType()==OP_BUY) Sell=true;

replace OP_BUY to OP_SELL & vice versa just for the record reversing the EA doesn't make a losing EA to be profitable

You can not call OrderType() unless you have an orderSelect before.
    datetime lastClosePrev;
    int      lastCloseType;
    for(int pos=0; pos < HistoryTotal(); pos++) if (
        OrderSelect(pos, SELECT_BY_POS, MODE_HISTORY)   // Only orders w/
    &&  OrderCloseTime()    > lastClosePrev             // not yet processed,
    &&  OrderMagicNumber()  == magic.number             // my magic number
    &&  OrderSymbol()       == Symbol()                 // and my pair.
    &&  OrderType()         <= OP_SELL){    // Avoid cr/bal forum.mql4.com/32363
        lastClose = OrderCloseTime();
        lastCloseType = OrderType();
    }
