Understanding Position Sizing: Beyond Just the Stop Loss
It's easy to get fixated on the perfect entry and exit, but position sizing often gets less attention than it deserves. It's not just about setting a stop loss; it's about deciding how much capital to expose to any single trade, ensuring that even if your stop is hit, your overall portfolio isn't significantly dented. For example, if you're risking 1% of your account on a trade, a losing streak won't wipe you out, giving you room to recover.
Think about this in context: a high-volatility pair like $EURCAD, currently trading around 1.60678, might require a smaller position size compared to a more stable asset, even with the same dollar risk on the stop. The wider swings mean your stop might need to be further away in pips, and to maintain consistent capital risk, your unit size needs to adjust. It's the core of capital preservation.
จริงครับ ขนาดพอร์ตนี่แหละที่ชอบทำให้ใจสั่นกว่า Stop Loss อีกนะ บางทีก็อยากเสี่ยงเยอะๆ แต่พอนึกถึงตอนโดน SL ติดๆ กันแล้วก็เหงื่อตกเลย
