Struct MacdSignal 

pub struct MacdSignal {
    pub fast: usize,
    pub slow: usize,
    pub signal: usize,
    /* private fields */
}

MACD Signal Strategy

Goes long when MACD line crosses above signal line. Exits when MACD line crosses below signal line. Emits short signals on bearish crossovers (execution gated by BacktestConfig::allow_short).

Fields

fast: usize

Fast EMA period

slow: usize

Slow EMA period

signal: usize

Signal line period

Implementations

impl MacdSignal

pub fn new(fast: usize, slow: usize, signal: usize) -> Self

Create a new MACD signal strategy

Trait Implementations

impl Clone for MacdSignal

fn clone(&self) -> MacdSignal

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MacdSignal

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

Formats the value using the given formatter.

impl Default for MacdSignal

fn default() -> Self

Returns the “default value” for a type.

impl Strategy for MacdSignal

fn name(&self) -> &str

Strategy name (for reporting)

fn required_indicators(&self) -> Vec<(String, Indicator)>

Required indicators this strategy needs.

fn setup(&mut self, indicators: &HashMap<String, Vec<Option<f64>>>)

Called once by the engine after indicator pre-computation, before the simulation loop. Strategies may cache references into the indicator map here to avoid per-bar HashMap lookups. The default implementation does nothing; pre-built strategies override this for performance.

fn warmup_period(&self) -> usize

Optional: minimum candles required before strategy can generate signals. Default is 1 (strategy can run from first candle).

fn on_candle(&self, ctx: &StrategyContext<'_>) -> Signal

Called on each candle to generate a signal.

fn htf_requirements(&self) -> Vec<HtfIndicatorSpec>

Higher-timeframe indicators required by this strategy.
