Struct Signal 

#[non_exhaustive]
pub struct Signal {
    pub direction: SignalDirection,
    pub strength: SignalStrength,
    pub timestamp: i64,
    pub price: f64,
    pub reason: Option<String>,
    pub metadata: Option<SignalMetadata>,
}

A trading signal generated by a strategy

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

direction: SignalDirection

Signal direction

strength: SignalStrength

Signal strength/confidence

timestamp: i64

Timestamp when signal was generated

price: f64

Price at signal generation

reason: Option<String>

Optional reason/description

metadata: Option<SignalMetadata>

Strategy-specific metadata (indicator values, etc.)

Implementations

impl Signal

pub fn long(timestamp: i64, price: f64) -> Self

Create a long signal

pub fn short(timestamp: i64, price: f64) -> Self

Create a short signal

pub fn exit(timestamp: i64, price: f64) -> Self

Create an exit signal

pub fn hold() -> Self

Create a hold signal (no action)

pub fn is_hold(&self) -> bool

Check if this is a hold signal

pub fn is_entry(&self) -> bool

Check if this is an entry signal (Long or Short)

pub fn is_exit(&self) -> bool

Check if this is an exit signal

pub fn with_strength(self, strength: SignalStrength) -> Self

Set signal strength

pub fn with_reason(self, reason: impl Into<String>) -> Self

Set reason/description

pub fn with_metadata(self, metadata: SignalMetadata) -> Self

Set metadata

Trait Implementations
