Dimensionamento de CFDs em pares voláteis como $BTCUSD vs. mais estáveis como $EURUSD

Traduzido automaticamente do original · Ler o original (English)

Ainda estou a começar com CFDs e a tentar perceber como as pessoas ajustam o seu dimensionamento para volatilidades tão diferentes. Em algo como $BTCUSD, um pequeno movimento pode ser uma percentagem enorme da minha conta se não tiver cuidado, mas depois em $EURUSD, parece que mal estou a mover a agulha com o mesmo tamanho proporcional. Vocês dimensionam os tamanhos das posições puramente com base no ATR, ou há um ajuste mental para o 'feeling' que vem com a experiência?

That's a great question, it really depends on your risk tolerance. I personally don't just use ATR for everything; for crypto pairs, I'll often reduce my standard position size even further to account for those crazy swings, even if ATR suggests a bigger size.

จริงครับ เรื่องการปรับขนาด position ตามความผันผวนนี่เป็นเรื่องสำคัญเลย ส่วนตัวผมก็ไม่ได้ใช้ ATR เพียวๆ ซะทีเดียว แต่จะดู Bollinger Bands ประกอบด้วย เพื่อดูว่าช่วงนั้นตลาดกำลังขยายตัวหรือหดตัวด้วยครับ แล้วค่อยมาปรับขนาดอีกที

This is a great question. I've been wondering the same thing. Do you factor in the margin requirements at all when you're thinking about sizing, or is it more about the potential PnL swing?
