    Hello semua,

    Belajar Code MQL4 tidaklah rumit,
    selama ini kita kesulitan karena tidak tahu harus memulai dari mana, menggunakan apa dan bagaimana tahapan kerja EA.

    Saya mau share code yang simple untuk membuat EA yang menggunakan 2 indicator Moving Average (MA) yang saling bersilangan (cross over) sebagai signal entry.
    Contoh ini juga sudah lengkap dengan peggunaan magicNumber.

    Code ini dibuat untuk tujuan belajar ya...

    Silahkan download file mql4 untuk dicoba dan pahami.
    Bila ada yang kurang jelas, silahkan balas balas comment atau bisa join group sharing code mql

    Bisa langsung digunakan.

    untuk aplikasi lebih luas atau pengembangannya, bisa ikut group diskusi kami t.me/codeMQL.
    Disitu kita bisa belajar dan sharing lebih banyak ttg code MQL4
