How is position size calculated?
Position size = (account balance × risk %) ÷ distance between entry and stop loss. This way, if your stop is hit, you lose exactly the amount you chose to risk — no matter how volatile the asset is.
How is the liquidation price estimated?
For a long position the approximation is entry × (1 − 1/leverage); for a short it is entry × (1 + 1/leverage). Real exchanges add maintenance margin and fees, so the actual liquidation happens slightly before this price. Always treat it as an optimistic estimate.
Does leverage change how much I should risk?
No. Leverage only changes the margin you must post, not the risk. Your risk is defined by position size × distance to stop loss. Higher leverage with the same position size just means less margin locked — and a closer liquidation price.
What is a good risk percentage per trade?
Most professional traders risk 1–2% of their account per trade. This keeps a losing streak survivable: five consecutive 2% losses cost about 10% of the account, which is recoverable.
This tool is for information only and is not financial advice. Liquidation prices are approximations — exchanges apply maintenance margin and fees that move the real liquidation closer to entry.
