嗨，Mladen。

我正在尝试在MT5中编写这个代码，但我认为我没有使用正确的实现方式。

我的想法是使用更多的指标，请给我一个提示...;-)

I need help to make this modular, because I will work with more indicators (6 to 8),
this is a sample to understand I'm trying to do..

in this sample:
I put only 3 indicadors.

//global variables
bool m_buy = true;
bool m_sell = true;
enum Signal{
   IN_OUT=0,  //in & out
   IN=1,      //in
   OUT=2,     //out
};

I have a EA with indicators that I want to mix and optimize it in BackTest.

//some sample data for signal for In/Out states only for exemplification
iT_InOut = IN_OUT;  //Itrend usage => In & Out
RSI_InOut = IN_;     //RSI usage =>only IN
MFI_InOut = OUT_;     //MFI usage =>only OUT
//

//this is the complete sequence IF I USE all signals in+out
//only to show the completly sequence (I will not use it)
m_buy=(m_it00[0]>m_it10[0] && m_it00[0]>m_it01[0] && m_rsi0[0]>m_rsi1[0] && m_mfi0[0]>m_mfi1[0]);
// The green is growing and more than red, RSI is growing, MFI is growing
m_sell=(m_it00[0]<m_it10[0] && m_it00[0]<m_it01[0] && m_rsi0[0]<m_rsi1[0] && m_mfi0[0]<m_mfi1[0]);
// The green falls and less than red, RSI falls, MFI falls

//now the skeleton that I'm trying to make work (in future I will use much more indicators)

              if(!PositionSelect(Symbol()))   ///No opened it's first entrance
                 {

大家好。

我真的需要帮助，我正在用waddah attar scalping指标建立一个专家，逻辑是有效的，一切都很好。

除了一件事，正如你在回测截图中看到的，在每个绿柱子上，专家都会开出一个买盘，红柱子也一样。我希望每个颜色变化只有一个交易。

我想要的是:

我希望每个颜色变化只有一个交易。

以下是我的代码。(做空也是如此)

//Trading decision.
   bool SendLong = false, SendShort = false;

    double clnowsell = iCustom(Symbol(),WAScalpingTimeFrame,"Waddah_Attar_Scalping",IPeriod,P1,P2,1,clbar);
    double clpresell = iCustom(Symbol(),WAScalpingTimeFrame,"Waddah_Attar_Scalping",IPeriod,P1,P2,1,clbar+1);

    double clnowbuy = iCustom(Symbol(),WAScalpingTimeFrame,"Waddah_Attar_Scalping",IPeriod,P1,P2,0,clbar);
    double clprebuy = iCustom(Symbol(),WAScalpingTimeFrame,"Waddah_Attar_Scalping",IPeriod,P1,P2,0,clbar+1);

   //Long trade

   //Specific system filters
   //if (some condition) SendLong = true;

   if (clnowbuy > 0) SendLong = true;

谁能提供一个简单的解决方案，请看第1265行，逻辑来自这里。

非常感谢!

danizani95 2016.12.06 17:08 #7257

大家好，我想编辑一个EMA-RSI指标，当4个EMA交叉发生且RSI>或<50时，可以显示一个向上或向下的箭头。

我的问题是，这些箭头一旦出现就不会刷新，如果我想检查条件是否仍然良好以显示箭头，我需要改变时间框架。你能告诉我哪里有问题吗？我把代码贴出来了。

谢谢你

嗨，姆拉登。

这是 "sample-ea-modular.mq5"，里面有一些代码......还有我想要的界面。

我想把它做成模块化，我的想法是分别优化每个指标的输入/输出。

如果我能够用 "sample-ea-modular.mq5 "来实现，我将改变真正的EA。

真正的基础是Ea-sample.mq5。(我发这个帖子只是为了让你看到所有的指标)

亲爱的@mladen,

如果你能解决下面提到的错误，请你非常高兴。

谢谢你...

"问题：当我连接到图表并使用自动调校时间时，有一个警告。

警告是这样的。警告，只在回测中使用手动GMToffsets。

自动GMT偏移计算只在实时/演示交易中起作用

而对于回测--策略测试，应该设置为FALSE。

这是否正常？或者我应该把自动GMT偏移量变成假的？

解答：我关闭了AutoGMTOffset，并手动设置GMT偏移。不再有警告信息，而且在演示中似乎工作得很好。你想啊。也许这是个错误。哦，是的，这绝对是个错误。

我看了看代码，一个 "else "操作要么被省略了，要么放错了位置。只有当UseAutoGMTOffset被设置为FALSE时，才应该发出这个消息。

所以，请忽略这条消息，并感到高兴。一切都在按（咳咳）设计的方式工作"。

oguz

像往常一样（你已经知道了），我不对反编译的代码进行评论，但我看到你在一个正确的轨道上：如果它能工作（选项），就使用它。如果不能用，就不要用。在我看来，这只是一个信息（而不是一个错误），所以...
