Question

外汇mt4编写EA，具体要求：用代码写出判断上一单(已经平仓的单子)是盈利还是亏损。

Answer 1

if(OrderSelect(OrdersHistoryTotal()-1,SELECT_BY_POS,MODE_HISTORY))
{
if(OrderProfit()>0)
{
Print("上一个单子盈利");
}else
{
Print("上一个单子盈利");
}
}

Answer 2

double LastTicketProfit()
{
datetime lasttime=D'2015.01.01 00:00';
double profit=-1.0;

if (OrdersHistoryTotal()==0) return profit;
for (int i=OrdersHistoryTotal()-1; i>=0; i--){
if (OrderSelect(i, SELECT_BY_POS, MODE_HISTORY)==true)
{
if (OrderSymbol() == Symbol() ){ //只统计当前对应货币对
if (OrderType() == OP_BUY || OrderType() == OP_SELL) {
if (OrderCloseTime()>lasttime){
lasttime = OrderCloseTime();
profit = OrderProfit();
}
}
}
}
}

return profit;
}
