Implementations

impl Okx

pub async fn fetch_balance(&self) -> Result<Balance>

Fetch account balances.

Returns

Returns a Balance structure with all currency balances.

Returns

Returns a vector of Trade structures representing user’s trade history.

impl Okx

pub async fn fetch_funding_rate_impl(&self, symbol: &str) -> Result<FundingRate>

Fetch current funding rate for a symbol.

Uses OKX GET /api/v5/public/funding-rate (public endpoint).

pub async fn fetch_funding_rates_impl( &self, symbols: &[&str], ) -> Result<Vec<FundingRate>>

Fetch funding rates for multiple symbols.

Calls fetch_funding_rate_impl for each symbol.

pub async fn fetch_funding_rate_history_impl( &self, symbol: &str, since: Option<i64>, limit: Option<u32>, ) -> Result<Vec<FundingRateHistory>>

Fetch funding rate history for a symbol.

Uses OKX GET /api/v5/public/funding-rate-history (public endpoint).

impl Okx

pub async fn set_leverage_impl( &self, symbol: &str, leverage: u32, margin_mode: Option<&str>, ) -> Result<()>

Set leverage for a symbol.

Uses OKX POST /api/v5/account/set-leverage endpoint.

Arguments

• symbol - Unified symbol (e.g., “BTC/USDT:USDT”)

impl Okx

pub fn builder() -> OkxBuilder

Creates a new OKX instance using the builder pattern.

This is the recommended way to create an OKX instance.

Example

use ccxt_exchanges::okx::Okx;

let okx = Okx::builder()
    .api_key("your-api-key")
    .secret("your-secret")
    .passphrase("your-passphrase")
    .sandbox(true)
    .build()
    .unwrap();

pub fn new(config: ExchangeConfig) -> Result<Self>

Creates a new OKX instance.

Arguments

• config - Exchange configuration.

pub fn new_with_options( config: ExchangeConfig, options: OkxOptions, ) -> Result<Self>

Creates a new OKX instance with custom options.

This is used internally by the builder pattern.

Arguments

• config - Exchange configuration.
• options - OKX-specific options.

pub fn base(&self) -> &BaseExchange

Returns a reference to the base exchange.

pub fn base_mut(&mut self) -> &mut BaseExchange

Returns a mutable reference to the base exchange.

pub fn options(&self) -> &OkxOptions

Returns the OKX options.

pub fn set_options(&mut self, options: OkxOptions)

Sets the OKX options.

pub fn id(&self) -> &'static str

Returns the exchange ID.

pub fn name(&self) -> &'static str

Returns the exchange name.

pub fn version(&self) -> &'static str

Returns the API version.

pub fn certified(&self) -> bool

Returns true if the exchange is CCXT-certified.

pub fn pro(&self) -> bool

Returns true if Pro version (WebSocket) is supported.

pub fn rate_limit(&self) -> u32

Returns the rate limit in requests per second.

pub fn is_sandbox(&self) -> bool

Returns true if sandbox/demo mode is enabled.

Sandbox mode is enabled when either:

• config.sandbox is set to true
• options.demo is set to true

Returns

true if sandbox mode is enabled, false otherwise.

Example

use ccxt_exchanges::okx::Okx;
use ccxt_core::ExchangeConfig;

let config = ExchangeConfig {
    sandbox: true,
    ..Default::default()
};
let okx = Okx::new(config).unwrap();
assert!(okx.is_sandbox());

pub fn is_testnet_trading(&self) -> bool

Returns true if demo trading mode is enabled.

This is an OKX-specific alias for is_sandbox(). Demo trading mode is enabled when either:

• config.sandbox is set to true
• options.demo is set to true

When demo trading is enabled, the client will:

• Add the x-simulated-trading: 1 header to all REST API requests
• Use demo WebSocket URLs (wss://wspap.okx.com:8443/ws/v5/*?brokerId=9999)
• Continue using the production REST domain (https://www.okx.com)

Returns

true if demo trading mode is enabled, false otherwise.

Example

use ccxt_exchanges::okx::Okx;
use ccxt_core::ExchangeConfig;

let config = ExchangeConfig {
    sandbox: true,
    ..Default::default()
};
let okx = Okx::new(config).unwrap();
assert!(okx.is_testnet_trading());

Returns the API URLs.

pub fn default_type(&self) -> DefaultType

Returns the default type configuration.

pub fn default_sub_type(&self) -> Option<DefaultSubType>

Returns the default sub-type configuration.

pub fn is_contract_type(&self) -> bool

Checks if the current default_type is a contract type (Swap, Futures, or Option).

This is useful for determining whether contract-specific API parameters should be used.

Returns

true if the default_type is Swap, Futures, or Option; false otherwise.

pub fn is_inverse(&self) -> bool

Checks if the current configuration uses inverse (coin-margined) contracts.

Returns

true if default_sub_type is Inverse; false otherwise.

pub fn is_linear(&self) -> bool

Checks if the current configuration uses linear (USDT-margined) contracts.

Returns

true if default_sub_type is Linear or not specified (defaults to Linear); false otherwise.

pub fn create_ws(&self) -> OkxWs

Creates a new WebSocket client for OKX.

Returns an OkxWs instance configured with the appropriate WebSocket URL based on the exchange configuration (production or demo).

Example

use ccxt_exchanges::okx::Okx;
use ccxt_core::ExchangeConfig;

let okx = Okx::new(ExchangeConfig::default())?;
let ws = okx.create_ws();
ws.connect().await?;

pub fn create_private_ws(&self) -> OkxWs

Creates a new private WebSocket client for OKX.

Returns an OkxWs instance configured with the private WebSocket URL. The caller must call login() on the returned client before subscribing to private channels.

pub fn signed_request( &self, endpoint: impl Into<String>, ) -> OkxSignedRequestBuilder<'_>

Creates a new signed request builder for authenticated API requests.

This builder encapsulates the common signing workflow for OKX API requests, including credential validation, timestamp generation, HMAC-SHA256 signing, and authentication header injection.

Arguments

• endpoint - API endpoint path (e.g., “/api/v5/account/balance”)

Returns

A OkxSignedRequestBuilder instance for fluent API construction.

Example

use ccxt_exchanges::okx::Okx;
use ccxt_exchanges::okx::signed_request::HttpMethod;
use ccxt_core::ExchangeConfig;

let okx = Okx::new(ExchangeConfig::default())?;

// Simple GET request
let data = okx.signed_request("/api/v5/account/balance")
    .execute()
    .await?;

// POST request with parameters
let data = okx.signed_request("/api/v5/trade/order")
    .method(HttpMethod::Post)
    .param("instId", "BTC-USDT")
    .param("tdMode", "cash")
    .param("side", "buy")
    .execute()
    .await?;
