SIRI PINE SCRIPT - Label, garisan dan jarak dari harga semasa

Kita gabungkan label dan lines dalam satu script untuk dapatkan jarak harga dari harga semasa ke 52w high dan 52w low.

Konsep yang sama boleh diguna pakai untuk membuat support atau resistance dan mengira jarak harga sama ada dalam nombor atau peratus.

Ikut kreativiti masing-masing.

Note : Dulu dah pernah buat. Kali ini saya tambah garisan vertical.
