关于指标代码-----（3行）的问题

1.为什么在deinit中出现了2个标记的函数？

2.为什么720值在标记的行上？

解释一下这段代码。

谢谢。

1.它们不在deinit()中，而只是在deinit()后面（在deinit()和start()之间）。 在mql中，你不需要遵循任何程序和函数 的编写顺序。你可以把init()放在代码的最后，它仍然可以工作。）

2.它将计算固定在每个刻度的720条。为什么？我认为你应该向作者询问这个问题。

ERAN123:
1.为什么有两个标记的函数在deinit中？

2.为什么标记线上的720值？

谢谢。
 

嗨，mladen

谢谢你的回放。

1.刚刚注意到这个问题（我把这个问题搞错了，没有注意到）。

2.它是真正的奥秘

 

待处理的订单 需要简单的帮助 !!!!!!!!

朋友们好

我有一个关于挂单的问题。

我有2个挂单，买入和卖出，一旦其中一个被击中，我就会关闭另一个。

我只是一个新手mql程序员，它超出了我现在的能力。

任何方向的朋友????

非常感谢。

 

你可以使用这样的东西。

void CleanPendingOrders()

{

bool trade.BuyEntered = false;

bool trade.SellEntered = false;

for (int i=OrdersTotal()-1; i>=0; i--)

{

OrderSelect(i, SELECT_BY_POS, MODE_TRADES);

//

//

//

//

//

if ( OrderSymbol()==trade.symbol && OrderMagicNumber()==MagicNumber )

{

int type = OrderType();

if (type==OP_BUY && !trade.ByEntered) trade.BuyEntered = true;

if (type==OP_SELL && !trade.SellEntered) trade.SellEntered = true;

if (type >OP_SELL && (trade.ByEntered || trade.BuyEntered))

OrderDelete(OrderTicket());

}

}

}

如果找到一个具有相同魔法号码和符号的正常订单，它将删除任何挂单。

非常感谢，我将检查 它。

再次感谢

 

它应该可以正常工作

祝你周末愉快

交易员朋友们，你们好!

我已经做了几个月的交易，我想在mql4中编写一个策略。

我执行一个带有获利 的订单，像这样

"OrderSend(Symbol(), OP_BUY, lots, Ask, 10, 30, Ask+takeprofit, "test", 12345, 0, Green); "

现在，当订单关闭时（T/P或S/L），我想做另一个同样的订单。

"OrderSend(Symbol(), OP_BUY, lots, Ask, 10, 30, Ask+takeprofit, "test", 12345, 0, Green);"

以此类推，这样只要之前的买入被关闭，它就会引入一个买入头寸。

我几天前开始学习mql4，我被卡住了。请帮助我!

 

你为什么不简单地计算一下当前开仓的订单数量（无论是买单还是卖单），当它为0时，开一个新仓？

嘿，MLaden是对的--你需要计算订单来检查你是否准备好了新的订单。

以下是你可能想要使用的函数。

它将计算你已经从选定的魔法数字 和订单类型中打开了多少个订单。

如果您将-1作为您的订单类型，它将按选定的魔法数字计算所有订单。

请享用。

int orderCount(int type,int magic)

{

int oc = 0;

for(int cnt = 0 ;cnt<OrdersTotal();cnt++)

{

OrderSelect(cnt, SELECT_BY_POS, MODE_TRADES);

if(OrderMagicNumber() == magic && (OrderType() == type || type == -1))

oc+=1;

}

return(oc);

}
