1.2. Cac Hinh Thuc Bieu Dien Ty Le Pho Bien
Du the gioi ca cuoc toan cau, ty le thuong duoc trinh bay duoi ba dinh dang chinh, va viec nam ro chung la buoc dau tien de lam chu cuoc choi:
a) Ty Le Thap Phan (Decimal Odds)
Day la hinh thuc pho bien nhat o chau Au va chau A (bao gom Viet Nam). Vi du: 2.50.
Cach tinh: Neu ban dat cuoc 100.000 VND voi ty le 2.50, tong so tien ban nhan ve (bao gom ca von) se la 100.000 x 2.50 = 250.000 VND. Loi nhuan rong cua ban la 150.000 VND.
Uu diem: Rat de tinh toan loi nhuan truc tiep.

Viec hieu ro cac hinh thuc nay giup ban de dang so sanh ty le giua cac nha cai khac nhau – mot ky nang then chot de tim kiem gia tri tot nhat.
Phan 2: Ty Le Nha Cai Khong Chi La Du Doan – Do La Xac Suat Ngam
Day la phan quan trong nhat ma da so nguoi choi bo qua. Ty le nha cai KHONG phai la xac suat thuc te cua mot su kien. Chung la xac suat da duoc ""dieu chinh"" de dam bao loi nhuan cho nha cai.
2.1. Giai Ma Xac Suat Ngam (Implied Probability)
Moi ty le cuoc deu an chua mot xac suat du doan. Ban co the chuyen doi ty le thap phan thanh xac suat ngam bang cong thuc sau:
$$\text{Xac suat ngam} = \frac{1}{\text{Ty le thap phan}}$$
Vi du: Neu ty le cho doi A thang la 2.00:
$$\text{Xac suat ngam} = \frac{1}{2.00} = 0.50 \text{ hay } 50\%$$
Dieu nay co nghia la nha cai dang ngam dinh doi A co 50% co hoi chien thang.
2.2. Margin (Bien Loi Nhuan) – ""Thue"" Cua Nguoi Choi
Neu ban cong tong xac suat ngam cua tat ca cac ket qua co the xay ra (vi du: Thang, Thua, Hoa trong bong da), tong so se luon lon hon 100%. Khoan chenh lech do chinh la Margin (hay Vig/Juice) – loi nhuan an toan ma nha cai tu dong tinh vao ty le cua ho.
Vi du Bong Da (Keo 1X2):
| Ket Qua | Ty Le | Xac Suat Ngam |
| :---: | :---: | :---: |
| Doi A Thang (1) | 2.20 | 1 / 2.20 = 45.45% |
| Hoa (X) | 3.40 | 1 / 3.40 = 29.41% |
| Doi B Thang (2) | 3.00 | 1 / 3.00 = 33.33% |
| Tong | | 108.19% |
Margin cua nha cai trong truong hop nay la $108.19\% - 100\% = 8.19\%$.
Tai sao dieu nay quan trong?
Nam duoc Margin giup ban nhan ra rang, de co loi nhuan lau dai, ban khong can phai thang 50% so lan cuoc neu ty le la 2.00. Ban can tim kiem nhung co hoi ma xac suat thuc te cua ban cao hon xac suat ngam ma nha cai dua ra.
Phan 3: Doc Vi Bien Dong Ty Le – Theo Doi Dong Tien Thong Minh
Mot trong nhung chi so manh me nhat de danh gia chat luong thong tin cua nha cai la su bien dong cua ty le cuoc theo thoi gian. Day la luc ma nhung chuyen gia thuc thu tim kiem ""gia tri"".
3.1. Su Khac Biet Giua Odds Mo va Odds Dong

3.2. Hien Tuong Ty Le Giam (Odds Dropping)
Khi ty le cho mot ket qua cu the bat dau giam (vi du: tu 2.50 xuong 2.20), dieu nay thuong am chi rang co mot luong lon tien duoc dat vao ket qua do.
Giai thich theo huong tieu cuc (Dam dong): Dam dong dang do tien vao cua do.

Viec theo doi ty le giam manh co the giup ban ""bat song"" thong tin truoc khi no tro nen ro rang voi cong chung.
