ตัวอย่าง EA ที่ใช้หลายกลยุทธ์ร่วมกัน
คำอธิบายองค์ประกอบหลักของ EA ที่ใช้หลายกลยุทธ์ร่วมกัน:
- กลยุทธ์ที่ใช้:
- Trend Following: ใช้ Trend MA เพื่อกำหนดแนวโน้มหลัก
- MA Crossover: ใช้การตัดกันของ Fast MA และ Slow MA
- RSI: ใช้ RSI เพื่อระบุภาวะ overbought และ oversold
- การตัดสินใจเข้าเทรด:
- Buy: เมื่อราคาอยู่เหนือ Trend MA และ (Fast MA ตัดขึ้นบน Slow MA หรือ RSI < oversold)
- Sell: เมื่อราคาอยู่ใต้ Trend MA และ (Fast MA ตัดลงใต้ Slow MA หรือ RSI > overbought)
- การจัดการความเสี่ยง:
- ใช้ Stop Loss และ Take Profit
- ใช้ Trailing Stop เพื่อปรับ Stop Loss ตามราคาที่เคลื่อนไหว
- การออกจากเทรด:
- ปิดเทรดเมื่อมีสัญญาณตรงข้ามเกิดขึ้น
