Enum PositionLimitErrorKind 

pub enum PositionLimitErrorKind {
    MaxPositionsReached {
        current: usize,
        maximum: usize,
    },
    MaxExposureReached {
        current_exposure: f64,
        max_exposure: f64,
    },
}

Represents errors related to position limits in trading operations.

This enum captures different types of limit violations that can occur when managing trading positions, such as exceeding the maximum number of allowed positions or reaching the maximum exposure threshold for a portfolio.

Variants

• MaxPositionsReached - Error indicating that the maximum number of allowed positions has been reached, preventing the creation of additional positions.

• MaxExposureReached - Error indicating that the maximum allowed financial exposure has been reached, preventing positions that would increase exposure.

Usage

This error type is typically used in position management systems, risk control mechanisms, and trading platforms to enforce safety limits and prevent excessive risk taking.

Variants

MaxPositionsReached

Error indicating the maximum number of positions has been reached

This variant is triggered when attempting to create a new position would exceed the configured maximum number of positions allowed in a portfolio or trading account.

Fields

current: usize

The current number of positions in the portfolio

maximum: usize

The maximum number of positions allowed

MaxExposureReached

Error indicating the maximum allowed exposure has been reached

This variant is triggered when a new position or modification would cause the total portfolio exposure to exceed the configured maximum risk threshold. Exposure is typically measured in monetary terms based on position value or risk.

Fields

current_exposure: f64

The current financial exposure level of the portfolio

max_exposure: f64

The maximum allowed exposure level
