Struct Position 

pub struct Position {
    pub quantity: Decimal,
    pub entry_price: Option<Decimal>,
    pub unrealized_pnl: Option<Decimal>,
    pub margin_used: Option<Decimal>,
    pub liquidation_price: Option<Decimal>,
    pub leverage: Option<Decimal>,
    pub time_exchange: DateTime<Utc>,
}

Represents an open position in a derivative instrument (perpetuals, futures, margin).

For spot instruments, positions are implicit in asset balances — this struct is only used for instruments that track position state separately from cash balances.

Fields

quantity: Decimal

Signed quantity: positive = long, negative = short, zero = flat.

Using signed quantity is the industry standard for derivatives and avoids a separate side field.

entry_price: Option<Decimal>

Average entry price. None if position is flat or entry price unavailable.

unrealized_pnl: Option<Decimal>

Unrealized PnL in quote currency. None if not provided by exchange.

margin_used: Option<Decimal>

Margin/collateral allocated to this position. None if not applicable.

liquidation_price: Option<Decimal>

Liquidation price. None for cross-margin or if not provided.

leverage: Option<Decimal>

Leverage setting. None if not applicable (e.g., spot-margin).

time_exchange: DateTime<Utc>

Exchange timestamp when this position state was reported.

Implementations

impl Position

pub const fn new( quantity: Decimal, entry_price: Option<Decimal>, unrealized_pnl: Option<Decimal>, margin_used: Option<Decimal>, liquidation_price: Option<Decimal>, leverage: Option<Decimal>, time_exchange: DateTime<Utc>, ) -> Position

impl Position

pub fn is_flat(&self) -> bool

Returns true if this position is flat (zero quantity).

pub fn is_long(&self) -> bool

Returns true if this is a long position (positive quantity).

pub fn is_short(&self) -> bool

Returns true if this is a short position (negative quantity).

pub fn abs_quantity(&self) -> Decimal

Returns the absolute position size.

Trait Implementations

impl Clone for Position

fn clone(&self) -> Position

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Position

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Position

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for Position

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for Position

fn cmp(&self, other: &Position) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for Position

fn eq(&self, other: &Position) -> 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 PartialOrd for Position

fn partial_cmp(&self, other: &Position) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl Serialize for Position

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
