如何只提取Zigzag指标提取的底部转折点？

Tjipke de Vries 2013.10.19 07:56 #11

jackprobe:

嗨，deVries。

谢谢你。是的，它就像你发来的图片一样。但我想知道如何编写代码。它必须计算之前的每一个Zigzag腿，然后画出Fibonacci水平，这样我们就知道当前/最后一个Zigzag走了多远。

编辑：我把代码发到了前面的帖子里。它不会画出斐波那契线...

谢谢

你能告诉我你是如何用这个指标得到0.0和100.0的数值的吗？

你能告诉我你是如何用这个指标得到0.0和100.0的值的吗？

我使用MT4菲波回撤工具手动制作的.....。:) 我想要的其实是那张图片，但还是不知道如何编码。

关于iCustom，我是否应该像下面这样调用它（调用你的TopBottomZigzag.ex4文件）？

double top[i] = iCustom(Symbol(),0,"TopBottomZigzag",ExtDepth,ExtDeviation,ExtBackstep,2,i);
double bottom[i] = iCustom(Symbol(),0,"TopBottomZigzag",ExtDepth,ExtDeviation,ExtBackstep,1,i);

谢谢

不，那是错误的缓冲区，你必须找到i的值，在哪个栏的顶部或底部将是什么？

如果我把它与我在CodeBase中发布的版本相比较，就会发现Zigzag在低点有线，在高点有线。

这是我在创建这个主题的指标之前用普通的Zigzag做的。

看看你是否找到了其中的逻辑

你好，deVries。

谢谢你的链接。我刚刚尝试用iCustom来调用你的指标，我把它命名为 "TopBottomZigzag.ex4" 。结果很好。这次菲波线是由代码创建的...:)

只是我仍然不能使前一个ZZ腿的Fibo .... :( 它总是只画最后一个ZZ腿。而且还不能定义Fibo水平线的长度 ...

谢谢你的好代码 ....

明天我将继续

这一部分

      topPrc = iCustom(Symbol(),0,"TopBottomZigzag",ExtDepth,ExtDeviation,ExtBackstep,2,shift);
      bottomPrc = iCustom(Symbol(),0,"TopBottomZigzag",ExtDepth,ExtDeviation,ExtBackstep,1,shift);

必须要改变

Tjipke de Vries 2013.10.20 05:37 #16

如果你看一下你的图片，你会发现斐波那契只在最后两个ZZ点的水平上绘制。

你的问题是 "不能使前一个ZZ腿的Fibo .... :( 它总是只画最后一个ZZ腿。而且还不能定义Fibo水平线的长度..."

所以你必须检查你的代码是怎么做的，以及它是如何产生你现在的结果的

.

我们想知道你的编码在这部分做了什么？

  for(shift=limit;shift>=0;shift--)  { 
      topPrc = iCustom(Symbol(),0,"TopBottomZigzag",ExtDepth,ExtDeviation,ExtBackstep,2,shift);
      bottomPrc = iCustom(Symbol(),0,"TopBottomZigzag",ExtDepth,ExtDeviation,ExtBackstep,1,shift);
      
      if ((topPrc>0)&&(topPrc!=EMPTY_VALUE)) {
         DnBuffer[shift]= topPrc + 0.0003;
         jmlTitik++;
         ObjectDelete(myObjName);
           ObjectCreate(myObjName, OBJ_FIBO, 0, Time[bottomCandle], prevPrc, Time[shift], topPrc);
         ObjectSet(myObjName, OBJPROP_LEVELWIDTH, objWidth);
         ObjectSet(myObjName, OBJPROP_LEVELSTYLE, objStyle); 
         ObjectSet(myObjName, OBJPROP_LEVELCOLOR, objLevelColor); 
         ObjectSet(myObjName, OBJPROP_COLOR, objColor);
         //-- ganz unten
         prevPrc = topPrc;
         topCandle = shift;
      }
      else if ((bottomPrc>0)&&(bottomPrc!=EMPTY_VALUE)) {
         UpBuffer[shift]= bottomPrc - 0.0003;         
         jmlTitik++;
         ObjectDelete(myObjName);
         ObjectCreate(myObjName, OBJ_FIBO, 0, Time[topCandle], prevPrc, Time[shift], bottomPrc);
         ObjectSet(myObjName, OBJPROP_LEVELWIDTH, objWidth);
         ObjectSet(myObjName, OBJPROP_LEVELSTYLE, objStyle); 
         ObjectSet(myObjName, OBJPROP_LEVELCOLOR, objLevelColor); 
         ObjectSet(myObjName, OBJPROP_COLOR, objColor);
         //-- ganz unten
         prevPrc = bottomPrc;
         bottomCandle = shift;
      }
   }

从一些打印语句开始，我们必须找出正在发生的事情。

for(shift=limit;shift>=0;shift--)  
      { 
      topPrc = iCustom(Symbol(),0,"TopBottomZigzag",ExtDepth,ExtDeviation,ExtBackstep,2,shift);
      bottomPrc = iCustom(Symbol(),0,"TopBottomZigzag",ExtDepth,ExtDeviation,ExtBackstep,1,shift);
//..
      Print("topPrc  =  ",topPrc,"  bottomPrc  =  ",bottomPrc);
//.....
      }

你看到发生了什么？

jackprobe 2013.10.20 12:26 #17

嗨，deVries。

我使用警报而不是打印。如果蜡烛在腿的内部（不是在腿的末端或开始），我们就无法捕捉到价格。但是在腿的末端，我们可以看到价格（请看图表上的红色和绿色箭头）。因此，我认为可以使用iCustom，但有一个错误的编码，我仍然不知道它在哪里。

编辑：也许我必须使用数组/缓冲区来保存所有的Z字形末端的信息（Z字形末端的价格&Z字形末端的蜡烛数&Z字形末端的保险数）。可能我必须使用3x1数组的类型=双数，或只是使用1x1数组的类型字符串（但首先必须做 "连接 "所有结束Zigzag点的信息）????

for(shift=limit;shift>=0;shift--)  {    
      topPrc = iCustom(Symbol(),0,"topBottomZZ-2",ExtDepth,ExtDeviation,ExtBackstep,2,shift);
      bottomPrc = iCustom(Symbol(),0,"topBottomZZ-2",ExtDepth,ExtDeviation,ExtBackstep,1,shift);
      
      Alert("topPrc  =  ",topPrc,"  bottomPrc  =  ",bottomPrc, " candle=", shift);
      
      if ((topPrc>0)&&(topPrc!=EMPTY_VALUE)) {
         Alert("Inside first If: topPrc  =  ",topPrc,"  bottomPrc  =  ",bottomPrc, " candle=", shift);
         DnBuffer[shift]= topPrc + 0.0003;
         jmlTitik++;
         ObjectDelete(myObjName);
         ObjectCreate(myObjName, OBJ_FIBO, 0, Time[bottomCandle], prevPrc, Time[shift], topPrc);
         ObjectSet(myObjName, OBJPROP_LEVELWIDTH, objWidth);
         ObjectSet(myObjName, OBJPROP_LEVELSTYLE, objStyle); 
         ObjectSet(myObjName, OBJPROP_LEVELCOLOR, objLevelColor); 
         ObjectSet(myObjName, OBJPROP_COLOR, objColor);
         //-- ganz unten
         prevPrc = topPrc;
         topCandle = shift;
      }
      else if ((bottomPrc>0)&&(bottomPrc!=EMPTY_VALUE)) {
         Alert("Inside second If: topPrc  =  ",topPrc,"  bottomPrc  =  ",bottomPrc, " candle=", shift);
         UpBuffer[shift]= bottomPrc - 0.0003;         
         jmlTitik++;
         ObjectDelete(myObjName);
         ObjectCreate(myObjName, OBJ_FIBO, 0, Time[topCandle], prevPrc, Time[shift], bottomPrc);
         ObjectSet(myObjName, OBJPROP_LEVELWIDTH, objWidth);

         ObjectSet(myObjName, OBJPROP_LEVELCOLOR, objLevelColor); 
         ObjectSet(myObjName, OBJPROP_COLOR, objColor);
         //-- ganz unten
         prevPrc = bottomPrc;
         bottomCandle = shift;
      }
   }

jackprobe 2013.10.20 15:04 #18

嗨，deVries。

是的，你是对的。如果我试图捕捉这个值，并把它放到数组中，结果总是0（零） ....
我还是不明白，为什么它可以显示箭头（代表ZZ的结束），但当我试图把它放入数组时，结果却是0......？

谢谢

     if ((topPrc>0)&&(topPrc!=EMPTY_VALUE)) {
         /// Alert("Inside first If: topPrc  =  ",topPrc,"  bottomPrc  =  ",bottomPrc, " candle=", shift);
         DnBuffer[shift]= topPrc + 0.0003;        
         resPrice[jmlTitik] = topPrc;
         resCandle[jmlTitik] = shift;
         resPos[jmlTitik] = 1;
         Alert("1 LastPrice =", resPrice[jmlTitik]);
         Alert("1 LastCandle =", resCandle[jmlTitik]);
         Alert("1 LastPos =", resPos[jmlTitik]);
         //-- ganz unten
         jmlTitik++;
         prevPrc = topPrc;
         topCandle = shift;
      }

Tjipke de Vries 2013.10.20 17:01 #19

使用代码库中的指标，那么代码必须是这样的

//   if ( counted_bars < 1 ) 
   
   for(shift=limit;shift>=0;shift--)  { 
      topPrc = iCustom(Symbol(),0,"Zigzag_with_line_at_lows_and_line_at_highs",ExtDepth,ExtDeviation,ExtBackstep,3,shift);
      bottomPrc = iCustom(Symbol(),0,"Zigzag_with_line_at_lows_and_line_at_highs",ExtDepth,ExtDeviation,ExtBackstep,4,shift);
      
      
       Print("topPrc  =  ",topPrc,"  bottomPrc  =  ",bottomPrc);
      
     }/*

在图表上测试这个，你会看到打印出来的数据（没有用的警报）。
