    Frequently asked questions

    How much of my account should I risk per trade?

    The standard risk-management rule is 0.5–2% of your account per trade. Most prop firms (FTMO, FundedNext) recommend 0.25–1% so you never breach the Daily Loss limit.

    What is 1 lot in forex?

    1 standard lot = 100,000 units of the base currency. A mini lot = 0.1 lot = 10,000 units. A micro lot = 0.01 lot = 1,000 units.

    Does this calculator account for leverage?

    Leverage does not change trade risk — it changes the margin requirement. Use the margin calculator to compute the required deposit.
