Struct PositionConfig 

pub struct PositionConfig { /* private fields */ }

Configuration for position sizing within a strategy.

Invariants

• max_position_pct must be in [0.0, 1.0]
• risk_per_trade_pct (if present) must be in [0.0, 1.0]

Implementations

impl PositionConfig

pub fn new( max_position_pct: Decimal, volatility_scaling: bool, risk_per_trade_pct: Option<Decimal>, ) -> Result<Self, PositionConfigError>

Create a new position config, validating all fields.

pub fn max_position_pct(&self) -> Decimal

Maximum position as a fraction of equity (e.g., 0.1 = 10%).

pub fn volatility_scaling(&self) -> bool

Whether to scale position size by inverse volatility.

pub fn risk_per_trade_pct(&self) -> Option<Decimal>

Risk per trade as a fraction of equity, if set.

Trait Implementations

impl Clone for PositionConfig

fn clone(&self) -> PositionConfig

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for PositionConfig

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for PositionConfig

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for PositionConfig

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for PositionConfig

fn eq(&self, other: &PositionConfig) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for PositionConfig

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
