Rounded down to your lot step. What rounding leaves on the table is shown above as the actual risk.

Why it rounds downRounding up would risk more than the figure you typed. It will never do that, so you get the largest lot that stays inside your limit.

Prices are live, specs are yoursEntry prefills from our own feed. Contract sizes are typical retail values and are editable, because they belong to your broker.

USD accountsResults are in dollars. A balance in another currency needs converting first — the sizing itself is unaffected.

A calculator, not adviceIt sizes the trade you describe. It does not know whether the trade is a good one, and nothing here is investment advice.
