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.

Baik Pak, nanti saya coba mengulang kembali edukasi dari youtubenya Pak SoeHoe, agar nantinya lebih cepat memahami yg diajarkan di sessi berikutnya. Terimakasih.

belum ada om, untuk tanya jawab kita fokuskan di forum ini

Rafael Benny · 31 Aug 2021

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.

saya kngin bertanya Kenapa saya mencoba Averaging seperti di video diatas tidak berjalan, saya ingin membuat logika ketika entry posisi Minus (-) dia akan averaging sesuai Pips dan pembatasan jumlah averaging yang ditentukan

RoziTrader · 26 Sep 2021

Memberikan pelajaran yang bermanfaat bagi sesama trader

Western · 30 Sep 2021

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

TRAD3R · 23 Nov 2021

Terima kasih Soehoe atas edukasi dasar-dasar MQL. Seperti dalam screenshot terlampir saya menuliskan enum (); ada error '(' beginning bracket expected dan 'Pilihan' - declaration without type, bgm koreksinya ?

meto.asmo · 27 Jul 2023

Ijin bertanya master suhu, apakah bisa higher high & lower low sebelumnya sebagai titik entry??
Terima kasih atas tanggapannya master
