  Saat mengatur kontrak, Anda dapat memilih rb1901/rb1905 Data pasar adalah rb1901, kontrak perdagangan order adalah rb1905

• Variabel

  Variabel adalah ruang yang terbuka di memori komputer untuk menyimpan data.

  Mengumumkan variabel pertama

  // Assign 1 to the variable a
  a:=1;
  

  Dalam M Language, perbedaan sederhana dibuat dari data volume:

  1. Data dengan nilai tunggal: hanya satu nilai, seperti 0, 1, abc
  2. Data deret: Deret data yang terdiri dari satu set data dengan nilai tunggal, seperti Close (harga penutupan), di mana Close berisi harga penutupan n siklus [ 10.1, 10.2, 10.3, 10.4, 10. 5... ]

  Membedakan dari tipe variabel

  1. Jenis string: harus menggunakan parcel, jenis string tidak diizinkan untuk digunakan secara langsung, Anda perlu mencocokkan output fungsi ke tampilan

  INFO(CLSOE>OPEN,'OK!');
  

  1. Tipe nilai: termasuk bilangan bulat, angka tanda mengapung (desimal)

  // integer
  int:=2;
  
  
  // decimal
  float:=3.1;
  

  1. Tipe Boolean, menggunakan 1 (untuk benar) atau 0 (untuk salah): 1, 0, benar atau salah, misalnya: A:=1>0; setelah pelaksanaan kode ini, nilai A adalah 1

  // The current period closing price is greater than -999, you will find that the return value of each cycle is 1, representing true, because the closing price is almost impossible to be negative
  Is_true:=Close>-999;
  

  1. Variabel global

  VARIABLE:VALUE1:10;     // Declare a global variable with a value of 10 and execute only once.
  

  • ### Aturan penamaan

  Dalam sebagian besar sistem, penamaan variabel tidak memungkinkan penggunaan sistem kata-kata yang disediakan (nama variabel bawaan, nama fungsi), seperti Close yang terkenal, C. Selain itu, bilangan murni tidak diizinkan, atau angka dimulai dengan, dan tidak bisa terlalu panjang, sistem yang berbeda, dan batas panjang yang berbeda berbeda. Pada kenyataannya, Anda tidak perlu membingungkan efisiensi sistem arus utama untuk analisis bahasa Inggris. Saya percaya bahwa M Language sangat ramah bagi penutur bahasa Inggris. Saya sarankan Anda menggunakan konvensi penamaan berikut:

  Bahasa Inggris + digariskan

    // output
    Move_avg_5:=MA(C,5);
  

  Jika Anda lebih suka bahasa Inggris, tolong biarkan orang memahami arti variabel Anda sebanyak mungkin. Jangan menggunakan metode penamaan seperti: A1, AAA, BBB... Percayalah, setelah beberapa hari, ketika Anda meninjau kode indikator Anda lagi, Anda akan sangat sakit karena kurangnya memori. Demikian pula, ketika Anda mengekspor kode ke orang lain, pola pikir pembaca pasti telah runtuh.

  Kemudian, mulai sekarang, gunakan M Language sebanyak yang Anda bisa! Saya berharap itu akan menjadi alat yang ampuh untuk analisis dan pengambilan keputusan Anda.

• Jenis data

  Jenis data adalah konsep dasar. dalam pemrograman, ketika kita menetapkan data eksplisit untuk variabel, variabel menjadi jenis data itu sendiri.

  • 1. jenis nilai:

    1、2、3、1.1234、2.23456 ……
  

  • Jenis string (str):

    '1' 、'2' 、'3' ，string type must be wrapped with ''
  

  • Data urutan:

    a collection of data consisting of a series of single-valued data
  

  • 4. Tipe Boolean (Boolean):

  Gunakan 1 untuk benar dan 0 untuk salah

  Contoh

    // Declare a variable of a numeric type
    var_int := 1;
    // Declare a variable of sequence data
    var_arr := Close;
    // String type can not be declared separately, you need to combine functions
    INFO(C>O, 'rising line');
  

• Operator

  Operasi dan perhitungan yang digunakan untuk mengeksekusi kode indikator, yang merupakan simbol dari operasi partisipasi.

  • Operator penugasan

  Digunakan untuk menugaskan nilai ke variabel

   - 1. `:`
  
  
  a colon, representing the assignment and outputting to the diagram (deputy diagram)
  
  
  ```
  Close1:Close;      // Assign Close to the variable Close1 and output it to the diagram
  ```
  
   - 2. `:=`
  
  
  The “colon equal”, representing the assignment, but is not output to the diagram (main diagram, subgraph...) and is not displayed in the status bar table.
  
  
  ```
  Close2:=Close;     // Assign Close to the variable Close2
  ```
  
   - 3. `^^`
  
  
  ^^ ,two ^ symbols represent assignments, assign values to variables and output them to the diagram (main diagram).
  
  
  ```
  lastPrice^^C;
  ```
  
   - 4. `..`
  
  
  .. ,two dot, The symbol represents the assignment, assigns a value to the variable and displays it in the status bar table, but does not output it to the diagram (main diagram, sub- diagram...).
  
  
  ```
  openPrice..O
  ```
  

  • ### Relasional operator

  Operator relasional adalah operator binokular yang digunakan dalam ekspresi bersyarat.

  Mengembalikan nilai: Jenis Boolean, tidak benar (1), harus salah (0)

   - 1. Greater than >
  
  
  ```
  // Assign the result of 2 > 1 to the rv1 variable, at this time rv1=1
  Rv1:=2>1;
  ```
  
   - 2. Less than <
  
  
  ```
  // returns false, which is 0, because 2 is greater than 1. :-)
  rv3:=2<1;
  ```
  
   - 3. Greater than or equal to >=
  
  
  ```
  x:=Close;
  // Assign the result of the operation with a closing price greater than or equal to ¥ 10 to the variable rv2
  // Note that since “close” is a sequence of data, when the close>=10 operation is performed, the essence is that each cycle is performed, so each cycle will have a return value of 1, 0.
  rv2:=Close>=10;
  ```
  
   - 4. Less than or equal to <=
  
  
  ```
  Omitted here
  ```
  
   - 5. Equal to =
  
  
  ```
  A:=O=C;     // Determine if the opening price is equal to the closing price.
  ```
  
   - 6. Not equal to <> 
  
  
  ```
  1<>2       // Judgment weather 1 is equal to 2 or not, the return value is 1 (true)
  ```
  

  • ### Operator Logis

    Return value: Boolean type, not true (1), must be false (0)
  

   1. Logic and &&, can use “and” instead, and the left and right sides of the connection must be true at the same time.
  

    // determine whether cond_a, cond_b, cond_c is true at the same time,
    cond_a:=2>1;
    cond_b:=4>3;
    cond_c:=6>5;
    cond_a && cond_b and cond_c;    // return value 1, true
  

   2. Logic or ||, can use “or” instead, “or” link the left and right sides, as long as the one side is true, the whole is true (return true)
  

    cond_a:=1>2;
    cond_b:=4>3;
    cond_c:=5>6;
    cond_a || cond_b or cond_c;    // return value 1, true
  

  • ### Operator aritmatika

    Return value: numeric type
  

  Ini adalah penyelesaian simbol operator aritmatika dasar, yang merupakan simbol yang digunakan untuk memproses empat operasi aritmatika.

   - **Plus +**
  
  
  ```
  A:=1+1;      // return 2
  ```
  
   - **Subtract -**
  
  
  ```
  A:=2-1;      // return 1
  ```
  
   - **Multiply \***
  
  
  ```
  A:=2*2;      // return 4
  ```
  
   - **Divide by /**
  
  
  ```
  A:=4/2;      // return 2
  ```
  

• Fungsi

  • ### Fungsi

  Dalam dunia pemrograman, function sebenarnya adalah sepotong kode yang mengimplementasikan fungsi tertentu dan dapat dipanggil oleh kode lain.

    function(param1,param2,……)
  

   - Composition：
  
  
  The function name (parameter 1, parameter 2, ...), there may be no parameters, there may be multiple parameters, such as MA(x, n); represents a simple moving average of the inner x returning n cycles, where MA() is a The function, x and n are the parameters of the function.
  
  
  When using a function, we need to understand the basic definition of the function, that is, what data can be obtained by calling the function. In general, functions have parameters. When we pass in parameters, we need to ensure that the data type passed in is compliant. At current stage, the code hinting function of most IDEs is very imperfect. They are not showing the certain data types for the parameters given, which gives us some troubles. The interpretation of MA(x,n) is:
  
  
  ```
  Return a simple moving average
  usage：
  AVG:=MA(X,N): N's simple moving average of X, algorithm (X1+X2+X3+...+Xn)/N,N supports variables
  ```
  
  
  This is very unfriendly explanation for beginners. Next, we thoroughly analyze the function and try to find a way to quickly learn and use the function.
  

  • ### Mengembalikan nilai

  Untuk mempelajari fungsi dengan cepat, kita harus memahami konsep yang disebut return value. Return, seperti namanya, adalah return, nilainya mewakili nilai konkret, data yang dapat diperoleh.

    // Because it will be used in the following code, use the variable return_value to receive and save the return value of function()
    // retrun_value := function(param1,param2);
    // for example：
    AVG:=MA(C,10); // AVG is retrun_value , “function” function is: MA function, param1 parameter: C is the closing price sequence data, param2 parameter: 10.
  

  • ### Parameter

  Kedua, konsep penting kedua dari fungsi adalah parameter, melewati dalam parameter yang berbeda, Anda bisa mendapatkan nilai yang berbeda kembali.

    // variable ma5 receives 5 day closing price moving average
    ma5:=MA(C,5);
    // variable ma10 receives 10 day closing price moving average
    ma10:=MA(C,10);
  

  Parameter pertama X dari variabel di atas ma5, ma10 adalah C (harga penutupan), pada kenyataannya C juga merupakan fungsi (mengembalikan urutan harga penutupan sejak pembukaan), tetapi tidak memiliki parameter. parameter kedua 5, 10,Ini digunakan untuk memberitahu fungsi MA (), kita ingin mendapatkan moving average dari harga penutupan selama berapa hari, melalui parameter, fungsi menjadi lebih fleksibel.

  • Cara belajar

    • Pertama, Anda perlu memahami fungsi fungsi, yang merupakan data yang dapat diberikan fungsi ini.
    • 2. Memahami jenis nilai balik, setelah semua, kita menggunakan fungsi untuk mendapatkan nilai balik.
    • 3. Kita perlu memahami jenis data parameter, MA (x, n), jika Anda tidak tahu jenis data parameter x, n, Anda tidak bisa mendapatkan nilai kembali dengan benar.

  Dalam pengantar fungsi berikut, gunakan, ikuti tiga prinsip di atas.

• Peningkatan bahasa

  • Programming campuran antara bahasa M dan bahasa JavaScript

    %%
    // here you can call any API function of FMZ Quant.
    scope.TEST = function(obj) {
        return obj.val * 100;
    }
    %% 
   Closing price: C;
  The closing price is magnified 100 times: TEST(C);
  The previous closing price is magnified 100 times: TEST(REF(C, 1)); // The mouse moves to the backtest K line and the variable value is displayed.
  
  
  

   - scope object
  
  
  scope object, you can add attributes and assign anonymous functions to attributes. An anonymous function referenced by this attributes can be called in the M language code section.
  
   - scope.getRefs(obj) function
  
  
  In the JavaScript code block, call the scope.getRefs(obj) function, which returns the data of the incoming obj object.
  

  %%%% berikut dari kode JavaScript paket simbolis akan mendapatkan harga penutupan C masuk ketika fungsi TEST© dipanggil dalam kode bahasa M. Fungsi scope.getRefs mengembalikan semua harga penutupan untuk data K-line ini. Karena throw stop interrupt routine digunakan, variabel arr hanya berisi harga penutupan Bar pertama dari k-line. Anda dapat mencoba menghapus throw stop dan itu akan mengeksekusi pengembalian terakhir kode JavaScript, mengembalikan semua data harga penutupan.

  
      %%
      scope.TEST = function(obj){
          var arr = scope.getRefs(obj)
          Log("arr:", arr)
          throw "stop"
          return
      }
      %%
      TEST(C);
  

   - scope.bars
  
  
  In the JavaScript code block, access all K line bars.
  
  
  The TEST function returns a value, 1 is the falling k-line and 0 is the rising line.
  
  
  ```
  %%
  scope.TEST = function(){
      var bars = scope.bars
      return bars[bars.length - 1].Open > bars[bars.length - 1].Close ? 1 : 0    // can only return values
  }
  %%
  arr:TEST;                                                                      
  ```
  
  
  ```
  # Note:
  # TEST Received anonymous function, the return value must be a numeric value
  # If the anonymous function has no parameters, write VAR:=TEST directly when calling TEST; write VAR:=TEST(); will report an error.
  # TEST in #scope.TEST must be uppercase.
  ```
  
   - scope.bar
  
  
  In the JavaScript code block, access the current bar.
  
  
  Calculate the average of “opening high but closing low” of k-line’s prices.
  
  
  ```
  %%
  scope.TEST = function(){
      var bar = scope.bar
      var ret = (bar.Open + bar.Close + bar.High + bar.Low) / 4
      return ret
  }
  %%
  avg^^TEST;
  ```
  
   - scope.depth
  
  
  Access the market depth data (order book)
  
  
  ```
  %%
  scope.TEST = function(){
      Log(scope.depth)
      throw "stop"             // Throw an exception after printing the depth data, pause.
  }
  %%
  TEST;
  ```
  
   - scope.symbol
  
  
  Get the current trading pair name string
  
  
  ```
  %%
  scope.TEST = function(){
      Log(scope.symbol)
      throw "stop"
  }
  %%
  TEST;
  ```
  
   - scope.barPos
  
  
  Get the K line Bar location.
  
  
  ```
  %%
  scope.TEST = function(){
      Log(scope.barPos)
      throw "stop"
  }
  %%
  TEST;
  ```
  
   - scope.get\_locals('name')
  
  
  This function is used to get the variables in the M language code part
  
  
  ```
  V:10;
  %%
  scope.TEST = function(obj){
      return scope.get_locals('V')
  }
  %%
  GET_V:TEST(C);
  ```
  
  
  ```
  # Note:
  # If a variable does not calculate data when the period is insufficient, this time the scope.get_locals function is called in the JavaScript code.
  # When get this variable, it will give an error: line:XX - undefined locals a variable name undefined
  ```
  

• Referensi multi-siklus

  • Gunakan: #EXPORT Formula Nama... #END untuk membuat rumus. Jika Anda hanya ingin mendapatkan data untuk periode yang berbeda, Anda juga dapat menulis rumus kosong tanpa perhitungan rumus.

  Rumus kosong adalah:

    #EXPORT TEST 
    NOP;
    #END           // End
  

  • Penggunaan: #IMPORT [MIN, periode, nama rumus] AS variabel nilai, rumus referensi, mendapatkan data periode yang ditetapkan (harga penutupan, harga pembukaan, dll., diperoleh dengan nilai variabel).

  Contoh kode:

    // this code demonstrates how to reference formulas of different cycles in the same code
    // #EXPORT extends the syntax, ending with #END as a formula, you can declare multiple
    #EXPORT TEST 
    Mean 1:EMA(C, 20);
    Mean 2:EMA(C, 10);
    #END // End
  
  
    #IMPORT [MIN,15,TEST] AS VAR15 // Reference formula, K line cycle is 15 minutes
    #IMPORT [MIN,30,TEST] AS VAR30 // Reference formula, K line cycle is 30 minutes
    CROSSUP(VAR15.Mean1, VAR30.Mean1),BPK;
    CROSSDOWN(VAR15.Mean2, VAR30.Mean2),SPK;
    The highest price of 15 mins:VAR15.HIGH;
    The highest price of 30 mins:VAR30.HIGH;
    AUTOFILTER;
  

• Deskripsi Mode

  • ### 1、Satu posisi pembukaan dan satu posisi penutupan model penyaringan sinyal

  Dalam model, dengan menulis fungsi AUTOFILTER untuk mengontrol dan mewujudkan penyaringan sinyal dari satu pembukaan dan satu penutupan.

  Memfilter model mendukung perintah: BK, BP, BPK, SK, SP, SPK, CLOSEOUT, tidak mendukung BK (5) dan instruksi lain dengan banyak

  E.g：

    MA1:MA(CLOSE,5);
    MA2:MA(CLOSE,10);
    CROSSUP(C,MA1),BK;
    CROSSUP(MA1,MA2),BK;
    C>BKPRICE+10||C<BKPRICE-5,SP;
    AUTOFILTER;
  

  • ### 2、penjumlahan atau pengurangan model posisi

  Fungsi AUTOFILTER tidak ditulis dalam model, memungkinkan sinyal posisi pembukaan terus menerus atau sinyal posisi penutupan terus menerus, yang dapat digunakan untuk meningkatkan atau mengurangi posisi.

  Komando yang didukung: BK(N), BP(N), SK(N), SP(N), CLOSEOUT, BPK(N), SPK(N, tidak mendukung posisi terbuka dan dekat tanpa lot. (1) Pengelompokan instruksi pendukung. (2) Ketika beberapa kondisi instruksi terpenuhi pada saat yang sama, sinyal dieksekusi dalam urutan di mana pernyataan bersyarat ditulis. Misalnya:

    MA1:MA(CLOSE,5);
    MA2:MA(CLOSE,10);
    CROSSUP(C,MA1),BK(1);
    CROSSUP(MA1,MA2),BK(1);
    C>BKPRICE+10||C<BKPRICE-5,SP(BKVOL);
  

  • ### 3、satu K-line dengan satu model sinyal

  Satu K-line dengan satu model sinyal dapat dibagi menjadi model harga penutupan dan model harga instruksi.

  1)Model harga akhir

  Garis K melewati sinyal perhitungan untuk menempatkan pesanan (perhitungan juga dilakukan selama pembentukan garis K. Pada saat ini, sinyal akan tidak pasti, dan sinyal yang muncul ketika garis k tidak selesai akan diabaikan, dan tidak akan ditempatkan pesanan)

  Arah sinyal konsisten dengan arah posisi tunggu, dan tidak ada kondisi hilangnya sinyal.

    E.g：
    MA1:MA(CLOSE,5);
    MA2:MA(CLOSE,10);
    CROSSUP(MA1,MA2),BPK;//5 cycle moving average line up cross 10 cycle moving average line to buy long.
    CROSSDOWN(MA1,MA2),SPK;//5 cycle moving average line down cross 10 cycle moving average line to sell short.
    AUTOFILTER;
  

  2)Model harga instruksi

  Terlepas dari apakah garis k selesai atau tidak, sinyal dihitung dan pesanan ditempatkan secara real time, yaitu pesanan ditempatkan sebelum garis K selesai;

  Jika arah posisi tidak cocok dengan arah sinyal di akhir garis k, posisi akan disinkronkan secara otomatis.

  E.g：

    MA1:MA(CLOSE,5);
    MA2:MA(CLOSE,10);
    CROSSUP(MA1,MA2),BPK;//5 cycle moving average line up cross 10 cycle moving average line to buy long.
    CROSSDOWN(MA1,MA2),SPK;//5 cycle moving average line down cross 10 cycle moving average line to sell short.
    AUTOFILTER;
  

  • ### 4、Satu K-line dengan model sinyal ganda

  Model ini menggunakan multsig atau multsig_min untuk mengontrol dan mengimplementasikan beberapa sinyal dari satu K-line.

  Terlepas dari apakah garis k selesai, menghitung sinyal dan menempatkan pesanan real-time.

  Sinyal tidak akan ditinjau, tidak ada kondisi sinyal menghilang, dan arah sinyal konsisten dengan arah posisi.

  Eksekusi berulang dalam garis K jika kondisi sinyal ganda terpenuhi

    E.g:
    MA1:MA(CLOSE,5);
    MA2:MA(CLOSE,10);
    CROSSUP(MA1,MA2),BK;
    C>BKPRICE+10||C<BKPRICE-5,SP;
    AUTOFILTER;
    MULTSIG(0,0,2,0);
  

  tambahan: 1、Mode penjumlahan dan pengurangan posisi, dua metode satu sinyal k-line: perintah penempatan harga penutupan dan perintah penempatan harga instruksi semuanya didukung.

  2、Model posisi penjumlahan dan pengurangan,juga mendukung sinyal k-line tunggal untuk menempatkan pesanan.

  Menambahkan dan mengurangi model posisi, menulis fungsi multsig atau multsig_min, mewujudkan beberapa kali penjumlahan dan pengurangan posisi pada satu k baris, atau mengurangi posisi beberapa kali.

• Tampilan Bagan

  • ### Diagram utama indikator tambahan

  Gunakan operator ^^ untuk mengatur indikator yang akan ditampilkan pada gambar utama saat menetapkan nilai untuk variabel.

    MA60^^MA(C, 60);  // Calculate the moving average indicator with a parameter of 60
  

  

  • ### Sub-diagram indikator tambahan

  Gunakan operator : untuk mengatur indikator yang akan ditampilkan pada diagram sekunder saat menetapkan nilai untuk variabel.

    ATR:MA(MAX(MAX((HIGH-LOW),ABS(REF(CLOSE,1)-HIGH)),ABS(REF(CLOSE,1)-LOW)),26);    // Assign a value to the ATR variable, The ":" symbol is followed by the formula for calculating the ATR
  

  Jika Anda tidak ingin menampilkan pada utama atau sub-diagram Gunakan operator ..

    MA60..MA(C, 60);  // Calculate the moving average indicator with a parameter of 60
  

  Anda dapat menggunakan DOT dan COLORRED untuk mengatur jenis baris, warna, dll sesuai dengan kebiasaan pengguna yang akrab dengan bahasa M.

• Masalah Umum

  Memperkenalkan masalah yang sering ditemui dalam persiapan indikator, biasanya poin yang perlu diperhatikan saat menulis indikator.

  • Perhatikan akhir ;.

  • Perhatikan bahwa kata kunci sistem tidak dapat dinyatakan sebagai variabel.

  • Perhatikan bahwa string menggunakan tanda kutip tunggal, misalnya: opening hanya satu tanda kutip.

  • Komentar

  Anotasi

   - ``` // The content of the comment ``` (the input method can be typed in both English and Chinese), which means that the code is not compiled during the execution process, that is, it does not execute // the content behind it. Usually we use the meaning of the code to facilitate the code review. Understanding, recall
  
   - ``` { Comment content } ``` Block comment.
  
  
  ```
  A:=MA(C,10);
  {The previous line of code is the calculation of the moving average.}
  ```
  
   - ``` (* Comment content *) ``` Block comment.
  
  
  ```
  A:=MA(C,10);
  (*The previous line of code is the calculation of the moving average.*)
  ```
  

  • ### Metode input

  Ketika menulis kode, seringkali menyebabkan kesalahan simbol karena metode input beralih antara bahasa Cina dan bahasa Inggris. Jenis umum adalah sebagai berikut: titik koma:, terminator; koma, tanda kurung (), dll, karakter yang berbeda ini dalam bahasa Cina dan bahasa Inggris perlu diperhatikan.

  • Logika yang rentan terhadap kesalahan

    1. Setidaknya tidak kurang dari tidak kurang dari: Operator relasional yang sesuai>=
    2. Paling tidak Paling tidak Tidak lebih: Operator relasional yang sesuai<=
