1. Moving Average (MA) — Duong trung binh dong

🌡️ MA giong nhiet ke do sot...

Neu nhiet do cao hon 37°C = bi sot
Neu gia cao hon duong MA = xu huong tang

MA giup "lam min" gia nhay len xuong de thay huong ro hon
  • SMA (Simple MA) — Trung binh don gian, tinh deu gia moi ngay
  • EMA (Exponential MA) — Uu tien gia gan nhat, nhay hon SMA, phan ung nhanh hon

Cach su dung:

  • Gia o tren MA → xu huong tang
  • Gia o duoi MA → xu huong giam
  • Golden Cross — MA ngan cat MA dai len → tin hieu mua
  • Death Cross — MA ngan cat MA dai xuong → tin hieu ban
💡 MA pho bien: EMA 20, EMA 50, SMA 200

Nhung van dong vien gioi co the chay tiep du met — giong do thi tang manh RSI co the vuot 70 lau!

RSI co gia tri tu 0-100, cho biet gia bi "mua qua nhieu" hay "ban qua nhieu"

  • RSI > 70 → Overbought (mua qua nhieu) → co the dao chieu giam
  • RSI < 30 → Oversold (ban qua nhieu) → co the dao chieu tang

⚠️ Chu y: RSI > 70 khong co nghia la phai ban ngay!
Trong xu huong tang manh, RSI co the o tren 70 rat lau
Luon dung cung tin hieu khac — RSI la "manh moi" khong phai "cau tra loi"

MACD Line = Toc do hien tai
Signal Line = Toc do trung binh truoc do
Histogram = Xe dang tang toc hay giam toc?

Neu toc do hien tai > toc do trung binh = xe dang tang toc = gia co the tiep tuc!

MACD cho biet "dong luc" cua gia — gia dang manh len hay yeu di?

Thanh phan:

  • MACD Line — EMA 12 tru EMA 26 (gia tri mac dinh)

  • Histogram duong va tang → Dong luc tang manh
  • Histogram am va tang → Dong luc giam manh

MACD Crossover Signal
