Penggunaan Buffer Jam untuk Pengumpulan Data di MetaTrader 5
Tujuan Indikator ini direka untuk membantu trader dalam mengumpul data bagi tujuan pemodelan. Seperti yang kita tahu, dummies waktu sering digunakan dalam pemodelan ekonomi. Indikator ringkas ini menyediakan setiap jam sebagai vektor buffer binari. Buffer akhir menyimpan waktu itu sendiri. Jika anda mengumpul data dari indikator lain ke dalam format CSV, sebagai contoh menggunakan fungsi CopyBuffer, indikator ini membolehkan anda menambah kolum dummy bagi jam yang sedang dikumpul sebagai data tambahan. Ini adalah kod yang mudah bagi mereka yang mengumpul data, contohnya untuk tujuan pembelajaran mesin, supaya anda mempunyai pembolehubah dummy (buffer 0 hingga 23) atau pembolehubah jam (buffer 24) untuk digunakan dalam pemodelan. Menelusuri Kod Dimulakan dengan mengisytiharkan nombor buffer dan nombor plot sebanyak 25: #property indicator_chart_window
#property indicator_buffers 25
#property indicator_plots 25 Pemilihan Buffer Menetapkan label buffer untuk tetingkap data: #property indicator_label1 "Jam 00"
#property indicator_label2 "Jam 01"
#property indicator_label3 "Jam 02"
#property indicator_label4 "Jam 03"
#property indicator_label5 "Jam 04"
#property indicator_label6 "Jam 05"
#property indicator_label7 "Jam 06"
#property indicator_label8 "Jam 07"
#property indicator_label9 "Jam 08"
#property indicator_label10 "Jam 09"
#property indicator_label11 "Jam 10"
#property indicator_label12 "Jam 11"
#property indicator_label13 "Jam 12"
#property indicator_label14 "Jam 13"
#property indicator_label15 "Jam 14"
#property indicator_label16 "Jam 15"
#property indicator_label17 "Jam 16"
#property indicator_label18 "Jam 17"
#property indicator_label19 "Jam 18"
#property indicator_label20 "Jam 19"
#property indicator_label21 "Jam 20"
#property indicator_label22 "Jam 21"
#property indicator_label23 "Jam 22"
#property indicator_label24 "Jam 23"
#property indicator_label25 "Jam" Penyataan Buffer Kemudian, kita isytiharkan buffer dan juga pembolehubah integer untuk jam hari yang akan dikira kemudian. double hourBuffer0[];

int bar_hour; Pemindahan Indeks dan Penggambaran Plot Set indeks untuk semua buffer sebagai data, dan matikan penggambaran menggunakan satu gelung (cuba melakukan pengindeksan dengan gelung menyebabkan ralat, jadi ini dilakukan satu persatu; tetapi gelung senang digunakan untuk PlotIndexSetInteger). // Assign buffers to index, hide from chart, show in Data Window

return(INIT_SUCCEEDED); Fungsi OnCalculate dan Gelung Program Seterusnya kita bergerak ke fungsi OnCalculate: Di sini kita set semua buffer kepada sifar, dan hanya mengubah yang sepadan dengan jam semasa kepada satu.
