Struct StrategyBuilder 

pub struct StrategyBuilder<E = (), X = ()> { /* private fields */ }

Builder for creating custom strategies with entry/exit conditions.

The builder enforces that both entry and exit conditions are provided before a strategy can be built.

Implementations

impl StrategyBuilder<(), ()>

pub fn new(name: impl Into<String>) -> Self

Create a new strategy builder with a name.

Example

let builder = StrategyBuilder::new("My Strategy");

impl<X> StrategyBuilder<(), X>

pub fn entry<C: Condition>(self, condition: C) -> StrategyBuilder<C, X>

Set the entry condition for long positions.

Example

let builder = StrategyBuilder::new("RSI Strategy")
    .entry(rsi(14).crosses_below(30.0));

impl<E> StrategyBuilder<E, ()>

pub fn exit<C: Condition>(self, condition: C) -> StrategyBuilder<E, C>

Set the exit condition for long positions.

Example

let builder = StrategyBuilder::new("RSI Strategy")
    .entry(rsi(14).crosses_below(30.0))
    .exit(rsi(14).crosses_above(70.0));

impl<E: Condition, X: Condition> StrategyBuilder<E, X>

pub fn with_short<SE: Condition, SX: Condition>( self, entry: SE, exit: SX, ) -> Self

Enable short positions with entry and exit conditions.

Example

let strategy = StrategyBuilder::new("RSI Strategy")
    .entry(rsi(14).crosses_below(30.0))
    .exit(rsi(14).crosses_above(70.0))
    .with_short(
        rsi(14).crosses_above(70.0),  // Short entry
        rsi(14).crosses_below(30.0),  // Short exit
    )
    .build();

pub fn build(self) -> CustomStrategy<E, X>

Build the strategy.

Example

let strategy = StrategyBuilder::new("My Strategy")
    .entry(rsi(14).crosses_below(30.0))
    .exit(rsi(14).crosses_above(70.0))
    .build();
