Struct OrderPreview 

#[non_exhaustive]
pub struct OrderPreview {
    pub cost: Option<f64>,
    pub commission: Option<f64>,
    pub margin: Option<f64>,
    pub warnings: Vec<String>,
}

What a broker estimates for an order it has not accepted, from Broker::preview. Every estimate is optional.

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.

cost: Option<f64>

The estimated cost of the order in the account’s currency.

commission: Option<f64>

The estimated commission in the account’s currency.

margin: Option<f64>

The margin the order would need in the account’s currency.

warnings: Vec<String>

What the broker warns of, such as a position the order would reverse.
