Marco320:
亲爱的MLaden。

接下来我可以在我的真实账户和Markets.com的模拟账户（差价合约）上获得图表。在Liquid Markets的模拟账户上，是否有问题？因为Liquid提供了大量的工具选择（尤其是MT4的期货），我想在该平台上把它显示出来。你能不能看到这个问题的出现，因为我找不到。

谢谢你，马可

这可能是由于该指标是一个反编译的指标。从Build 500开始，metarader就阻止了此类指标的编译。

你好，MLaden。

谢谢，但奇怪的是，我使用的所有经纪公司的MT4平台都是500版本的。

问候马可

我有一个EA，我想在其中使用部分获利功能。我对这个功能进行了编码，有一次工作得很好，其他时候就不行了。我不知道问题出在哪里...

亲爱的Mladen或MrTools，你能不能看一下代码，给我一个建议，让我找到这个错误并解决部分获利功能？

我看不出你对 "小数 "变量使用的是什么值，但这可能是你问题的原因。订单的结果部分也必须符合手数步长值（意思是：如果手数步长是0.1，你不能尝试关闭0.11手）。检查在不成功的部分平仓后的最后一个错误是什么（你可以通过简单地在像这样的行后添加一个注释来做到这一点。

bER=" error="+gle+" "+ErrorDescription(gle)。

if (gle>1) Comment(bER);

因为代码中的logwrite函数没有操作性。

Chrisstoff 2013.10.02 11:14 #1555

Mladen,

谢谢你的答复。

嗯，我缩短了代码，因为一个帖子不可能超过10,000个字符。所以，在原来的代码中，小数变量是在init()中，如下图。

LotStep = MarketInfo(Symbol(),MODE_LOTSTEP);

if(LotStep == 0.01) {Decimals = 2;}

if(LotStep == 0.1) {Decimals = 1;}

if(LotStep == 1) {Decimals = 0;}[/PHP]

Yes, logwrite function is not functionable in the code posted, also because of the shortening. Normally it looks like:

[PHP]

void logwrite (string filename, string mydata)

{

int myhandle;

string wcalend=TimeToStr(CurTime(),TIME_DATE|TIME_SECONDS);

Print(mydata+" "+wcalend);

if(IsTesting()) return(0);

myhandle=FileOpen(Symbol()+"_"+filename, FILE_CSV|FILE_WRITE|FILE_READ, ";");

if(myhandle>0)

{

FileSeek(myhandle,0,SEEK_END);

FileWrite(myhandle, mydata+" "+wcalend);

FileClose(myhandle);

}

所以，我认为问题的出现不是因为小数变量。

这样一来，小数变量就应该没问题了

无论如何，请检查在订单（部分）关闭不成功的情况下，你得到的错误代码是什么？

Hock 2013.10.02 11:35 #1557

mladen:
我看到你没有使用神奇数字，所以我的假设是，神奇数字或符号是什么并不重要。在这种情况下，首先要检查是否已经有一个开放的订单--像这样。

if (OrdersTotal()<1)

{

ticket=OrderSend(Symbol(), OP_BUY, lots, Ask, 3, 0, 0);

stop=(Ask-stopsize*Point);

prof=(Ask+profsize*Point);

OrderModify( ticket, OrderOpenPrice(), stop, prof, 0, Blue);

}

如果你决定使用神奇数字和符号检查，那么最好做一个函数，计算指定符号和/或神奇数字的已开订单。

谢谢mladen。

如果（OrdersTotal()<1

这解决了我的问题。

总共可以订购一个，但我希望每一对货币都能打开。

对不起，我误解了。

但我的意思是在每个货币对中执行一个订单并停止。例如。

现在我在欧元兑美元开立订单，只执行一个订单。那么其他货币也可以在同一时间打开，执行一个订单。很抱歉，我的英语不好。

添加这个:

int TotalOrders = 0;

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

{

if (OrderSelect(i,SELECT_BY_POS,MODE_TRADES))

if (OrderSymbol() == Symbol())

TotalOrders++;

}

在if (OrdersTotal()<1) 一行之前，用if (TotalOrders<1) 替换这一行。这样一来，每个符号只允许有一个开仓订单

{
