Struct PositionSizing 

Source 
pub struct PositionSizing {
    pub point_value: f64,
    pub lot_size: f64,
    pub quantity_step: f64,
    pub leverage: f64,
}
Expand description

Instrument economics used by long and short position drawings. Quantities are lots; one lot contains lot_size units, each worth point_value in the account currency per price point. Defaults retain unit sizing without rounding.

Fields§

§point_value: f64

Account-currency value of one price point per underlying unit.

§lot_size: f64

Underlying units per displayed lot.

§quantity_step: f64

Permitted lot increment; zero leaves the quantity unrounded.

§leverage: f64

Notional value divided by required capital; positive and finite.

Implementations§

Source§

impl PositionSizing

Source

pub fn is_valid(&self) -> bool

Whether the economics are finite and positive, with a nonnegative quantity step.

Source

pub fn required_capital(&self, entry: f64, quantity: f64) -> Option<f64>

Required capital: absolute entry notional divided by leverage, in account currency. Returns None for invalid settings or a nonpositive or nonfinite quantity.
