嗨，mladen。

有时间看一下这个吗？

友好的问候 CJA

嗨，mladen。

我只是想让你知道，我已经得到了我的尾随代码请求的解决方案，所以你可以把这个问题从你的todo列表中删除。

注意：CJA

Mladen Rakic 2013.01.20 06:27 #3242

很高兴你解决了这个问题

祝你进一步编码和交易愉快

你好。

我需要检查我的EA的最后一笔平仓单是盈利还是亏损。

我想检查EA的最后两个平仓盈利订单，并将其相加。

问题是我在同一个账户中有几个EA，所以有必要用特定的MagicNumber检查历史订单。我尝试了几种模式，但没有成功。

你能帮助我吗？

谢谢你。

这个函数返回最后一次平仓的订单利润（正如你所看到的，你也可以指定神奇的数字作为参数，所以它解决了你的多个实例的问题）。

double lastOrderProfit(int magicNumber=0)

{

datetime lastTime = 0;

double lastProfit = 0;

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

{

if (OrderSelect(i,SELECT_BY_POS, MODE_HISTORY)==false) break;

if (magicNumber!=0)

if (OrderMagicNumber() != magicNumber) continue;

if (OrderSymbol() != Symbol()) continue;

if (OrderCloseTime() <= lastTime) continue;

lastTime = OrderCloseTime();

lastProfit = OrderProfit()+OrderSwap()+OrderCommission();

}

return(lastProfit);

}

你只需检查该函数的返回值是正数还是负数。

所以我只需要用我的魔法号码调用这个函数，它就会给我带来我的EA的最后一笔平仓订单的利润，对吗？

Mladen Rakic 2013.01.26 12:53 #3246

是的，它是正确的

dasio 2013.01.26 13:56 #3247

mladen:
是的，这是对的

谢谢你。

但是，如果我启动EA，历史上没有订单，我如何才能在我的EA平仓的情况下调用这个功能？

Mladen Rakic 2013.01.26 14:38 #3248

那么首先使用这个函数。

int closedSoFarForMagic(int magicNumber=0)

{

int closedSoFar=0;

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

{

if (OrderSelect(i,SELECT_BY_POS, MODE_HISTORY)==false) break;

if (magicNumber!=0)

if (OrderMagicNumber() != magicNumber) continue;

if (OrderSymbol() != Symbol()) continue;

closedSoFar++;

}

return(closedSoFar);

}

如果closedSoFarForMagic()>0，那么你就知道历史上已经有特定魔法数字的平仓订单，然后你可以检查最后的订单利润。

How to code? 如何在两个均线之间填充颜色？？？这么个简单的程序为什么画不出线呢？请教牛牛们。

Mladen Rakic 2013.03.16 20:12 #3250

thefxpros,

首先检查指标的名称。

""MA -fatailvma 3"

那里应该是 "fantail"。

另外，在对iCustom()指标的调用中，你缺少了缓冲区的编号。我只是猜测这是你想实现的目标

buffer1 = iCustom(NULL, 0, "MA - fatail vma 3", VMA1_ADXLenght, VMA1_Weighting, VMA1_Length, VMA1_Mode,0, i);

buffer2 = iCustom(NULL, 0, "MA - fatail vma 3", VMA1_ADXLenght, VMA2_Weighting, VMA2_Length, VMA2_Mode,1, i);[/PHP]
