Numbers your platform will actually accept.

Every calculator here is computed from Orbex's live contract specifications — the same ones the terminal enforces. Sign in with your account to size positions, price volatility stops and value a portfolio against real quotes.

• Sized to your broker's grid

  Lot sizes snapped to Orbex's real contract size, lot step and minimum stop distance — not a textbook approximation that gets rejected.

• Volatility stops, measured

  Where the stop belongs from actual ATR, and the position that fits it, answered in one step.

• It refuses rather than guesses

  When a specification is missing a field, you get the field name — never a confident number built on a guess.
