减少未结头寸

有没有人知道如何关闭/减少一半的头寸。我们应该调用什么函数？

例如。将一个未结头寸从10手减少到5手，而不开立另一个相反方向的交易？

Ovidiu Marius 2009.09.26 21:27 #2062

被称为 "部分关闭"。

bool OrderClose( int ticket, double lots, double price, int slippage, color Color=CLR_NONE)

只需指定要关闭多少手。

你好。

试试这个方法

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

if (OrderSelect(i, SELECT_BY_POS)) {

if (OrderSymbol()==Symbol()&&OrderType()==0) {

Ans=OrderClose(OrderTicket(),alLots,Bid,2);// Order closing

}

if (OrderSymbol()==Symbol()&&OrderType()==1) {

Ans=OrderClose(OrderTicket(),alLots,Ask,2);// Order closing

}

只要关闭5手的订单，像这样。

OrderClose(OrderTicket(),5.0,.......)

嗨，罗杰。

非常感谢你的帮助。同时，我设法修复了它的工作。

OrderSend(Symbol(),OP_BUY,alLots,Ask,3,0,0,EA_Tester,Magic);

if(OrderSelect(OrdersTotal()-1, SELECT_BY_POS)==true) {

alTicker = OrderTicket();

Alert("Bought! ", alTicker);

} else Print("OrderSelect failed error code is ",GetLastError());

[/CODE]

Like that I found alTicker (after opening position) which I close later on.

But your code I will use to optimize my Closing function. Sorry for maybe "beginner's code", I am into mq4 just 2 days ... will improve - I promise

Thanks again

Roger09:
Try this way

[CODE]

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

if (OrderSelect(i, SELECT_BY_POS)) {

if (OrderSymbol()==Symbol()&&OrderType()==0) {

Ans=OrderClose(OrderTicket(),alLots,Bid,2);// Order closing

}

if (OrderSymbol()==Symbol()&&OrderType()==1) {

Ans=OrderClose(OrderTicket(),alLots,Ask,2);// Order closing

}

需要帮助修改指标

嗨，所有的程序员。

我在论坛上发现了一个指标（货币头寸），可以显示我正在交易的当前头寸。现在我想找人帮我把这个指标改成在图表底部使用外部窗口，同时字体和颜色也可以改变。我不擅长编程。非常感谢。
