    Mau tanya Pak, saya menaruh 2 perintah Comment ( ) contoh:
    Comment("Test Satu");
    Comment("\nTes Dua");
    tapi yang tampil adalah yang terakhir saja yaitu Test Dua
    Apakah benar hanya perintah Comment( ) terakhir saja yang tampil?
    Bila demikian, artinya saya perlu menggabungkan kalimat terlebih dahulu, seperti:
    Comment("Test Satu"+"\nTes Dua");

    Terimakasih.

    Kalau perintah Comment memang begitu.

    Kalau mau buat seperti yg ada dalam harapan mas maka perintahnya adalah ObjectCreate(...), itu pelajaran kedua nanti. Mungkin Jumat, atau minggu. dengan perintah ini maka kita bisa mengatur ukuran, nama font, warna, posisi, dll.

    Mau tanya Pak untuk tugas 2:
    1. bagaimana cara merapikan tampilan nilai balance, equity, dan profit agar tampil rata kanan
    2. saya mencoba memindahkan code tampilan nilai ke dalam event OnTick() karena nilainya perlu uptodate
    namun nilai yang ditampilkan kenapa lebih lambat dibanding yg tampil di terminal (tidak realtime)
    Sementara ini dulu pertanyaan saya. Terimakasih.

    met gabung, sebelumnya sy jg suka kutak2 katik EA dengna cara koboi, maklum hanya modal basic bahasa C, ada pertanyaan yg selama ini suka sy bingung walau kyknya terlalu dini disisi, yaitu kadang sy suka pakai function iCustom, pada suatu indicator, pertanyaannya, kalau indicator tersebut terlalu banyak nilainya ) Value, bagaimana meminimalisasi / membuat EA itu jd ringan...hal ini benar2 terasa kalau kita membuat dashboard dari suatu indicator, terima kasih
