Trait TradingFormatter 

pub trait TradingFormatter: Send + Sync {
    // Provided methods
    fn price(&self, _symbol: &str, _price: f64) -> Option<String> { ... }
    fn quantity(&self, _symbol: &str, _quantity: f64) -> Option<String> { ... }
    fn spread(&self, _symbol: &str, _spread: f64) -> Option<String> { ... }
    fn pip_value(&self, _symbol: &str, _value: f64) -> Option<String> { ... }
}

Host text for the numbers of the order ticket, the depth ladder and the account tables.

Every method receives the symbol the number belongs to, so differently formatted instruments keep their own text. Return None to keep the built-in text: the symbol’s price decimals for prices, spreads and pip values, and the decimals of the quantity step for quantities. Install it with Trading::set_formatter.

Provided Methods

fn price(&self, _symbol: &str, _price: f64) -> Option<String>

A price, such as a limit price, a bid or an average price.

fn quantity(&self, _symbol: &str, _quantity: f64) -> Option<String>

A quantity, in the symbol’s trading units.

fn spread(&self, _symbol: &str, _spread: f64) -> Option<String>

The difference between the ask and the bid, in price units.

fn pip_value(&self, _symbol: &str, _value: f64) -> Option<String>

The value of one pip of the order in the account’s currency.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
