รบกวนช่วยแก้ไข อีเอให้หน่อย ครับ
ออเดอร์ทีเปิด เมื่อ ema ตัดกัน แต่เมื่อ ราคาย้อนกลับ และ ema ตัดกันรอบใหม่
ออเดอร์ที่เปิดไป ก็จะถูกปิดไปด้วย พร้อมกับเปิด ออเดอร์ใหม่ ตาม ema ที่ตัดกันในรอบใหม่
อยากให้ ออเดอร์ที่เปิดไป ตามema ที่ตัดกันในครั้งแรก ไม่ปิดลง แม้เส้น ema วก กลับมา
ในทิศทางตรงกันข้าม ครับ
เช่น ema ตัดขึ้น ออเดอร์ถูกเปิด แต่ผ่านไปสักพัก ราคาย้อนกลับ
เส้น ema ตัดลง ออเดอร์ก็จะถูกปิด พร้อมกับเปิดออเดอร์ใหม่
ตามที่เส้น ema ตัดลง ครับ
