Frequently Asked Questions
What is position sizing in crypto trading?
Position sizing determines how much of your capital to risk on a single trade. Proper sizing protects your account from large losses. Most professional traders risk 1-2% of capital per trade.
How do I calculate position size from risk?
Divide your max acceptable loss by the distance to your stop loss (as a fraction of entry price), then multiply by leverage. This calculator does it automatically.
What's the 1% rule in trading?
Never risk more than 1-2% of your total capital on a single trade. If your account is $10,000, maximum loss per trade = $100-200. This rule preserves capital during losing streaks.
How does stop loss distance affect position size?
A tighter stop allows a larger position for the same risk amount. A wider stop requires a smaller position. Always set stop loss first, then calculate position size.
