Frequently asked questions

How is position size calculated?

Amount at risk = account size × risk %. Position size (units) = amount at risk ÷ |entry price - stop loss price|. This means your loss is capped at exactly your chosen risk % if the stop is hit, regardless of leverage.

What risk % per trade should I use?

Most professional risk-management frameworks cap risk at 0.5-2% of account size per trade, so a string of losses doesn't meaningfully damage the account. Higher than 2-3% per trade is generally considered aggressive.

What does 'leverage needed' mean?

It's the position value divided by your account size - i.e. how much leverage you'd need to open a position of that size with your full account as margin. If it's above your comfort level, reduce risk % or widen your stop.
