Frequently asked questions
- How much should I risk per trade?
- A common guideline is 0.5–2% of account balance per trade. Risking 1% means a single loss costs 1% of the account, so a losing streak stays survivable. This tool defaults to 1%; move the slider to match your own plan.
- What's the difference between a lot, a mini lot, and a micro lot?
- A standard lot is 1.0 (100,000 units in forex). A mini lot is 0.1 (one-tenth) and a micro lot is 0.01 (one-hundredth). The calculator shows all three so you can pick the size your broker supports — most accept 0.01-lot steps.
- How do I size a gold (XAU/USD) position?
- Set the instrument to Gold, then enter your stop in points or as entry and stop prices. The calculator converts your risk into lots. Gold moves more than most forex pairs, so stops are usually wider and lot sizes smaller for the same risk.
- What are prop-firm risk rules?
- Most funded and prop-firm programs cap risk per trade (often 1–2%) and enforce daily and maximum drawdown limits. Turn on prop-firm mode to get a warning whenever your risk % rises above the usual 2% ceiling.
- How is position size calculated?
- Risk amount = balance × risk %. Lot size = risk amount ÷ (stop distance in pips × pip value per lot). Each instrument carries a preset pip or point value per standard lot, so you only supply balance, risk %, and stop distance.
- Does account currency change the result?
- Preset pip values here are quoted in USD. The currency selector only changes the display symbol — it does not convert exchange rates, which would need live FX data. If your account isn't in USD, read the figures as USD-equivalent and adjust by your FX rate.
