Module constants 

Module containing global constants used throughout the library

Constants

BASE_DELAY_MS

Base delay in milliseconds used for proximity-based delays in the rate limiter This value is used to calculate wait times when approaching rate limits

DAYS_TO_BACK_LOOK

Default number of days to look back when fetching historical data

DEFAULT_ACCOUNT_ID

Sentinel value used for account_id when IG_ACCOUNT_ID is not configured.

DEFAULT_API_VERSION

Default IG API version used for authentication when IG_API_VERSION is not set: v3 (OAuth).

DEFAULT_CONFIG_RATE_LIMIT_BURST_SIZE

Default burst size of the configured rate limiter (crate::application::config::RateLimiterConfig::burst_size).

DEFAULT_CONFIG_RATE_LIMIT_MAX_REQUESTS

Default request budget of the configured rate limiter (crate::application::config::RateLimiterConfig::max_requests).

DEFAULT_CONFIG_RATE_LIMIT_PERIOD_SECONDS

Default period of the configured rate limiter, in seconds (crate::application::config::RateLimiterConfig::period_seconds).

DEFAULT_DATABASE_MAX_CONNECTIONS

Default size of the Postgres connection pool (crate::application::config::DatabaseConfig::max_connections).

DEFAULT_DATABASE_URL

Credential-less placeholder used for DATABASE_URL when it is not configured.

DEFAULT_MAX_RETRIES

Default maximum number of retries for transient HTTP failures when the MAX_RETRY_COUNT environment variable is unset.

DEFAULT_ORDER_BUY_LEVEL

A constant representing the default buy level for orders.

DEFAULT_ORDER_SELL_LEVEL

A constant representing the default sell level for orders.

DEFAULT_PAGE_SIZE

Default page size for API requests

DEFAULT_RATE_LIMIT_BURST_SIZE

Fallback burst capacity used when crate::application::config::RateLimiterConfig::burst_size is configured as zero. Preserves the historical default of allowing a small burst.

DEFAULT_REST_BASE_URL

Default IG REST gateway: the demo environment.

DEFAULT_REST_TIMEOUT_SECS

Default REST request timeout in seconds (crate::application::config::RestApiConfig::timeout).

DEFAULT_RETRY_DELAY_SECS

Default base delay in seconds between retries when the RETRY_DELAY_SECS environment variable is unset. Used as the base for exponential backoff.

DEFAULT_SLEEP_TIME

Default sleep time in hours if not specified in environment (24 hours)

DEFAULT_WS_RECONNECT_INTERVAL_SECS

Default delay between Lightstreamer reconnection attempts, in seconds (crate::application::config::WebSocketConfig::reconnect_interval).

DEFAULT_WS_URL

Default Lightstreamer endpoint: the demo environment. Production requires an explicit opt-in via IG_WS_URL or a crate::application::config::WebSocketConfig supplied by the caller.

DEPRECATED_INFINITE_RETRY_CAP

Compatibility retry cap for the deprecated “infinite” retry constructors (crate::model::retry::RetryConfig::infinite and crate::model::retry::RetryConfig::with_delay). Unbounded retry is banned (PR #26); these constructors now clamp to this large-but-finite value so existing callers keep compiling while never looping forever.

ERROR_COOLDOWN_SECONDS

Cooldown time in seconds when hitting max errors (5 minutes)

FALLBACK_RATE_LIMIT_MAX_REQUESTS

Fallback replenishment budget (requests per period) used when crate::application::config::RateLimiterConfig::max_requests is configured as zero, which is structurally invalid.

HISTORICAL_RATE_LIMIT_PER_SECOND

Conservative per-app historical-price request budget, in requests per second, enforced by the rate limiter for endpoints under prices/.

MAX_CONSECUTIVE_ERRORS

Maximum number of consecutive errors before forcing a cooldown

MAX_RETRY_DELAY_SECS

Maximum backoff delay in seconds. Exponential backoff (base * 2^attempt) saturates at this cap — the cap is the policy, so rounding down to it is intentional and documented.

PROACTIVE_REFRESH_MARGIN_V2_SECS

Proactive-refresh safety margin for API v2 (CST / X-SECURITY-TOKEN) sessions, in seconds (5 minutes).

PROACTIVE_REFRESH_MARGIN_V3_SECS

Proactive-refresh safety margin for API v3 (OAuth) sessions, in seconds.

SAFETY_BUFFER_MS

Additional safety buffer in milliseconds added to wait times This provides extra margin to ensure rate limits are not exceeded

TRADING_HISTORICAL_BURST_SIZE

Burst capacity for the derived trading and historical rate-limit buckets.

TRADING_RATE_LIMIT_PER_SECOND

Conservative per-app trading request budget, in requests per second, enforced by the rate limiter for order / position mutations (positions/otc, workingorders/otc).

USER_AGENT

User agent string used in HTTP requests to identify this client to the IG Markets API.

V2_SESSION_LIFETIME_SECS

Lifetime of an IG API v2 (CST / X-SECURITY-TOKEN) session, in seconds (21600 = 6 hours).
