Leverage and exposure
In futures you trade with leverage: a small amount of margin controls a larger position. Position size = margin × leverage. Higher leverage means less margin per dollar of position, but also that a smaller adverse move can trigger liquidation. Risk management in futures means sizing so that (1) your loss at stop loss equals your chosen risk, and (2) you are not so overleveraged that normal volatility wipes your margin.
Liquidation awareness
Liquidation occurs when your equity in the position falls to the level the exchange requires to keep it open. Exchanges have maintenance margin rules; if price moves against you enough, the position is closed. A futures position size calculator that shows margin and liquidation context helps you avoid taking sizes that are too large for your account and leverage.
Example
$10,000 capital, 1% risk ($100). Long BTC at $100,000, stop $98,000. Stop distance $2,000/unit → quantity = 0.05. Position = $5,000. At 10× leverage, margin = $500. If price hits $98,000 you lose $100. Your stop is 2% away; with 10× that is 20% of margin, so you still have buffer before liquidation. Use the trading risk calculator to run this for any pair and leverage.
FAQ
- What is margin in futures?
- Margin is the collateral you post to open a leveraged position. Position size = Margin × Leverage. If you have $1,000 margin and 10× leverage, your position size is $10,000.
- Does leverage increase my loss at stop loss?
- No. Once position size and stop loss are set, your loss at that stop is fixed. Leverage only affects how much margin you need. A futures position size calculator sizes by risk first, then shows required margin.
- When does liquidation happen?
- When losses consume your margin and the exchange closes the position to prevent negative balance. Keeping position size and stop loss within your risk % and being aware of liquidation distance helps avoid it.
- How much should I risk per futures trade?
- Same idea as spot: many traders use 0.5–2% of capital per trade. The calculator applies that % to get risk amount, then derives position size and margin from your entry and stop.
