    Ayo sekarang kita belajar buat EA menggunakan Price Action, strategi/metode apalagi itu??? metode deteksi harga tanpa indikator dengan pola sederhana maupun kompleks dengan tambahan unsur lain (tingkat fibo, support dan resistance dll) silahkan tambahkan sendiri

    Strategi / Metode
    Inside Bar/ Di dalam Bar adalah bar yang memiliki tubuh dan sumbu terkandung sepenuhnya dalam kisaran sebelumnya (ibu) bar. Tinggi dalam bar terletak lebih rendah dan rendah terletak lebih tinggi dari yang ibu bar. Ibu dan di dalam bar membentuk pola dianggap sinyal potensial entri.

    Ini adalah pola dua sisi, karena mungkin menunjukkan baik pembalikan, atau kelanjutan tren.
    untuk lebih jelasnya silakan lihat gambar berikut:
    [​IMG]
    [​IMG]
    Aturan yang dipakai :
    • Pola Inside Bar lebih baik digunakan pada jangka waktu yang lebih tinggi, seperti H4 atau D1.
    • Pola dapat menunjukkan baik pembalikan tren atau kelanjutan.
    • Terapkan tambahan alat analisis grafis untuk entri yang lebih tepat, termasuk garis tren, tingkat support / resistance, level Fibo, pola Harga Aksi lainnya, dll
    • Gunakan pending order untuk menghindari entri pasar prematur atau salah.
    • Jangan gunakan Inside Bar/dalam bar berulang kali terjadi di pasar datar sebagai sinyal masuk pasar.

    Cara masuk pasarnya bagaimana?????

    begini nich

    Sekarang bagaimana menterjemahkan dalam bahasa MQL agar bisa dipake di dalam EA

    Code:
    //+------------------------------------------------------------------+
    //|                                                Price Action.mq4 |

      return(INIT_SUCCEEDED);
      }

      {

      }
    //+------------------------------------------------------------------+

    //+------------------------------------------------------------------+
    void OnTick()
      {
    //---
    
      }
    //+------------------------------------------------------------------+
    yang di atas adalah EA kosong masih belum di apa-apain, belum di isi dengan strategi price action

    Kita perlu definisikan candle di dalam setelah candle ditutup untuk itu diperlukan variable baru untuk menetapkan nilai-nilai mereka ntar jadinya seperti ini :
    Code:
    //+------------------------------------------------------------------+
    //|                                                Price Action.mq4 |
    //|                                                          ngasqus |
    //|                                              https://soehoe.com |

    double  open1,//candle pertama Open price
    open2,    //candle kedua Open price
    close1,  //candle pertama Close price
    close2,  //candle kedua Close price
    low1,    //candle pertama Low price
    low2,    //candle kedua Low price
    high1,    //candle pertama High price
    high2;    //candle kedua High price
    //+------------------------------------------------------------------+
    //| Expert initialization function                                  |
    //+------------------------------------------------------------------+
    int OnInit()
      {
    //---
    
    //---
      return(INIT_SUCCEEDED);
      }
    //+------------------------------------------------------------------+
    //| Expert deinitialization function                                |
    //+------------------------------------------------------------------+
    void OnDeinit(const int reason)
      {
    //---
    
      }
    //+------------------------------------------------------------------+
    //| Expert tick function                                            |
    //+------------------------------------------------------------------+
    void OnTick()
      {
    //-Menentukan harga dari candle yang diperlukan-
      open1        = NormalizeDouble(iOpen(Symbol(), Period(), 1), Digits);
      open2        = NormalizeDouble(iOpen(Symbol(), Period(), 2), Digits);
      close1      = NormalizeDouble(iClose(Symbol(), Period(), 1), Digits);
      close2      = NormalizeDouble(iClose(Symbol(), Period(), 2), Digits);
      low1        = NormalizeDouble(iLow(Symbol(), Period(), 1), Digits);
      low2        = NormalizeDouble(iLow(Symbol(), Period(), 2), Digits);
      high1        = NormalizeDouble(iHigh(Symbol(), Period(), 1), Digits);
      high2        = NormalizeDouble(iHigh(Symbol(), Period(), 2), Digits);
      }
    //+------------------------------------------------------------------+
    sebagai contoh, jika candle pertama bearish (candle 2) sedangkan inside barnya bullish (candle 1) mari ditambahkan ke dalam kode fungsi OnTick

    Code:
     if(open2>close2 && //candle ke 2 is bullish
          close1>open1 && //candle  is bearish
          high2>high1 &&  //the bar 2 High exceeds the first one's High
          open2>close1 && //the second bar's Open exceeds the first bar's Close
          low2<low1)      //the second bar's Low is lower than the first bar's Low
    O iya belum ditambahkan variable lainnya
    Code:
    extern int    interval          = 20;                              //Interval
    extern double  lot              = 0.1;                              //Lot Size
    extern int    TP                = 300;                              //Take Profit
    extern int    magic            = 555124;                          //Magic number
    extern int    slippage          = 2;                                //Slippage
    extern int    ExpDate          = 48;                              //Expiration Hour Order
    extern int    bar2size          = 800;                              //Bar 2 Size

    emang saya ambil contoh dari https://www.mql5.com/en/articles/1771 buat bantu teman-teman biar lebih semangat belajarnya. Jika ada yang ingin buat EA dengan strategi tertentu mari kita buat bersama untuk pembelajaran juga

    Bagi yang ingin BT pake TF Daily baru bisa buka OP tapi jarang banget
