Understanding Position Sizing: It's Not Just How Much You Buy

Too many new traders focus solely on entry and exit points, completely overlooking the crucial element of position sizing. This isn't just about how many shares of $PLTR you buy, or how many $ETHUSD units you pick up; it's about determining the appropriate amount of capital to risk on any single trade relative to your total account size. A common mistake is using a fixed dollar amount for every trade, regardless of the setup's volatility or stop-loss distance. If your stop on a $PLTR long is tight at say, $165 from $172, your potential loss per share is small. You can size up more to hit your desired risk per trade.

Conversely, if you're trading something like $ETHUSD with a wider stop, your per-unit risk is higher. You must reduce your position size to keep the total dollar risk constant across different trades. A good rule of thumb for many is to risk no more than 1-2% of their total trading capital on any single trade. This protects your account from a few bad trades wiping you out and allows you to stay in the game long enough for your edge to play out.
