Understanding Position Sizing: Not Just How Much, But Why

Look, everyone talks about risk-reward, but that's just half the picture. Position sizing is where the rubber meets the road. It's not about how many shares you can afford to buy, but how many you should buy relative to your stop loss and your total account equity. For instance, if you're looking at $NZDCAD and your analysis suggests a move, but your stop needs to be wide, say 50 pips, and you only want to risk 1% of your account on that single trade, you adjust your position size accordingly. Don't go throwing the same lot size on every trade just because you feel like it. That's a recipe for disaster. It's the difference between being able to take multiple small losses and still be in the game, versus one bad trade wiping you out. Mathematically determine your risk per trade, then size your position. Simple math, but it's often ignored. Keep it tight.
