Implementations

impl Ticker

pub fn new(symbol: String, timestamp: i64) -> Ticker

Creates a new ticker with required fields.

Arguments

• symbol - Trading pair symbol
• timestamp - Ticker timestamp in milliseconds

pub fn spread(&self) -> Option<Price>

Calculates the bid-ask spread.

Returns

Returns Some(Price) if both bid and ask are available, otherwise None.

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

Calculates the spread as a percentage of the bid price.

Returns

Returns the spread percentage if both bid and ask are available and bid > 0.

pub fn is_stale(&self, threshold_ms: i64) -> bool

Checks if ticker data is stale based on a time threshold.

Arguments

• threshold_ms - Maximum age in milliseconds before data is considered stale

Returns

Returns true if ticker age exceeds the threshold.
