Understanding Position Sizing: More Than Just 'How Much'

Been seeing a few newer folks on here asking about "how much should I invest in X." It's a common question, but the answer isn't a fixed percentage of your total portfolio, nor is it simply what you can afford to lose. Position sizing is actually a critical risk management tool that needs to be calculated in conjunction with your stop-loss and overall account risk. For example, if you're risking 1% of your account per trade, and your stop loss on a particular setup means a 100-pip move, then your position size needs to reflect that 100-pip move equaling 1% of your account. It's not just about $AUDUSD trading at 0.68949; it's about how much leverage that particular move would require to hit your predetermined risk tolerance. This is how you ensure no single trade, even a high-conviction one, can cripple your account. It takes discipline to stick to the math, especially when you feel like scaling up on a 'sure thing,' but it's the bedrock of longevity in this game.
