Nisbah Tenaga Arah Volume-Peras (VADER) menggunakan pergerakan harga (perpindahan) dan jumlah yang berkaitan (usaha) untuk menganggarkan
Saya sentiasa menjadi peminat konsep analisis teknikal yang mudah, dan yang mengintegrasikan kedua-dua tindakan harga dan jumlah bersama-sama - Konsep di sebalik VADER benar-benar mudah.
Mari kita berjalan melalui kerana kita mengelakkan terlalu teknikal:
Pergerakan harga yang besar yang dikaitkan dengan jumlah yang besar bermakna pembeli (jika pergerakan naik) atau penjual (apabila pergerakan turun) serius dan
Analoginya dengan VADER, adalah bahawa kita melihat pergerakan harga (perubahan penutupan antara 2 bar) sebagai perpindahan (atau hasil tindakan) dan jumlah yang berkaitan sebagai
kita kemudian mengambil purata tenaga relatif itu dalam setiap arah (positif = membeli dan negatif = menjual) dan mengira tenaga bersih.
Perhatikan bahawa kita
