OKX CEX Market Data CLI

Compliance notice: This skill provides raw market data only. No strategy, recommendation, or optimization logic is embedded. All indicator outputs are objective numerical values; interpretation and trading decisions remain solely with the user.

Public market data for OKX: prices, order books, candles, funding rates, open interest, instrument info, and technical indicators. All commands are read-only and require no API credentials.

Skill routing

• Market data / indicators → okx-cex-market (this skill)
• Account balance / positions → okx-cex-portfolio
• Place / cancel orders → okx-cex-trade
• Grid / DCA bots → okx-cex-bot

Preflight

Before running any command, follow ../_shared/preflight.md. Use metadata.version from this file's frontmatter as the reference for Step 2.

Install

npm install -g @okx_ai/okx-trade-cli
okx market ticker BTC-USDT   # verify

Market data commands return the same public data regardless of demo/live mode — no API credentials required. If the user's profile has demo=true set and they want live data context, they can use --live to confirm they are in live mode (it has no effect on public market data but clarifies environment). Always inform the user which environment is active (demo or live) when it is relevant to their query. No confirmation needed before running any market command. Add --json to any command for raw OKX API v5 response. Add --env to wrap the output as {"env", "profile", "data"}.

Command Index

#	Command	Description
1	okx market ticker <instId>	Last price, 24h high/low/vol/change%
2	okx market tickers <instType>	All tickers for SPOT / SWAP / FUTURES / OPTION

9	okx market mark-price --instType <type> [--instId <id>]	Mark price (SWAP / FUTURES / OPTION)
10	okx market index-ticker [--instId <id>] [--quoteCcy <ccy>]	Index price (e.g., BTC-USD)
11	okx market price-limit <instId>	Upper/lower price limits (SWAP / FUTURES only)
12	okx market open-interest --instType <type> [--instId <id>]	Open interest in contracts and base currency
13	okx market instruments-by-category --instCategory <3|4|5|6|7>	Discover instruments by asset category: 3=Stock tokens (AAPL/TSLA), 4=Metals (gold/silver), 5=Commodities (oil/gas), 6=Forex (EUR/USD), 7=Bonds
13†	okx market stock-tokens	Deprecated — use instruments-by-category --instCategory 3 instead
14	okx market filter --instType <SPOT|SWAP|FUTURES> [--sortBy <field>] [--sortOrder <asc|desc>] [--limit <n>] [--baseCcy <ccy>] [--quoteCcy <ccy>] [--settleCcy <ccy>] [--instFamily <fam>] [--ctType <linear|inverse>] [--minLast <n>] [--maxLast <n>] [--minChg24hPct <n>] [--maxChg24hPct <n>] [--minMarketCapUsd <n>] [--maxMarketCapUsd <n>] [--minVolUsd24h <n>] [--maxVolUsd24h <n>] [--minFundingRate <n>] [--maxFundingRate <n>] [--minOiUsd <n>] [--maxOiUsd <n>]	Screen / rank instruments by multi-dimensional criteria (price, volume, OI, funding rate, market cap). Prints Total: N + a ranked table of matching instruments (No results only when nothing matches). Add --json for the raw OKX API v5 response (structurally unchanged).
15	okx market oi-history <instId> [--bar <5m|15m|1H|4H|1D>] [--limit <n>] [--ts <ms>]	OI history time series with bar-over-bar delta for a single instrument

For period-based indicators (ema/ma/wma/rsi/macd/bb/…) the CLI applies a sensible default period when --params is omitted (e.g. EMA/RSI → 14, MACD → 12,26,9, BB → 20,2) so values render without you specifying params; explicit --params always wins. If no values come back, the CLI prints a visible hint (try --params …) — never silent.
19	okx market pair-spread <instIdA> <instIdB> [--bar <5m|15m>] [--window <window>] [--backtest-time <ms>]	Spread statistics (abs + ratio: mean/stdDev/median/min/max) over a lookback window; supports backtest mode

Operation Flow

Step 1 — Identify data type and load reference

User intent	Reference to load
Price, candles, order book, recent trades	{baseDir}/references/price-data-commands.md
Technical indicators (RSI, MACD, EMA, BB, KDJ, SuperTrend, AHR999, Rainbow, etc.)	{baseDir}/references/indicator-commands.md
Funding rate, mark price, open interest, price limit, index ticker	{baseDir}/references/derivatives-commands.md
Screen / rank instruments; find top movers, high-OI, high-volume contracts	Use okx market filter directly
OI history time series for a single instrument	Use okx market oi-history directly
OI change scanner; find contracts with large OI shifts	Use okx market oi-change directly
Pair spread statistics; mean-reversion / pairs-trade sizing	Use okx market pair-spread directly
List instruments, discover stock tokens, metals/commodities/forex/bonds, find option instIds	{baseDir}/references/instrument-commands.md
Multi-step or cross-skill workflows; MCP tool names	{baseDir}/references/workflows.md

Step 2 — Run commands immediately

All market data commands are read-only — no confirmation needed.

Step 3 — No writes, no verification needed

All commands in this skill are read-only.

Edge Cases

• instId format: SPOT BTC-USDT · SWAP BTC-USDT-SWAP · FUTURES BTC-USDT-250328 · OPTION BTC-USD-250328-95000-C · Index BTC-USD · Stock token TSLA-USDT-SWAP · Metals/Commodities/Forex/Bonds: use instruments-by-category to discover valid instIds first
• OPTION listing: instruments --instType OPTION requires --uly BTC-USD; if unknown, run open-interest --instType OPTION first to discover active instIds
• funding-rate / price-limit: SWAP only · mark-price: SWAP / FUTURES / OPTION only
• candles --bar: uppercase — 1H not 1h; use --after <ts> to paginate back into historical data (back to 2021); index-candles supports --history for extended history
• ⚠️ Large historical range: before fetching with --after/--before, estimate candle count = time_range_ms / bar_interval_ms. If estimate > 500, tell the user the estimated count and ask for confirmation before proceeding. This prevents silently filling the context window.
• indicator --bar: uses 1Dutc not 1D, 1Wutc not 1W — different from candle bar values
• market filter sortBy values: last chg24hPct marketCapUsd volUsd24h fundingRate oiUsd listTime — default volUsd24h
• market filter ctType: linear or inverse (SWAP/FUTURES only); omit for SPOT
• market filter quoteCcy: comma-separated list supported, e.g. --quoteCcy USDT,USDC
• market filter SPOT + quoteCcy: when --instType SPOT, the API returns instruments across all quote currencies (USDT, USDC, BTC, ETH, etc.) mixed together — this pollutes sort order and bloats results. Always pass --quoteCcy USDT by default unless the user explicitly asks for other quote currencies.
• market filter chg24hPct: value is a percentage number — --minChg24hPct -5 means -5%, --maxChg24hPct 10 means 10%
• market oi-history ts: Unix ms timestamp; returns bars with ts ≤ this value for historical pagination
• market oi-history / oi-change bar: valid values 5m 15m 1H 4H 1D — default 1H. Server accepts case variants (1h == 1H) but prefer canonical casing.
• market oi-history limit: 1–500 (default 50)
• market oi-change instType: only SWAP or FUTURES supported (not SPOT)
• market oi-change minAbsOiDeltaPct: filters by absolute OI change — 1.0 keeps only rows where |oiDeltaPct| ≥ 1%
• market oi-change sortBy values: oiUsd oiDeltaUsd oiDeltaPct absOiDeltaPct volUsd24h fundingRate last — default oiDeltaPct (signed). Use absOiDeltaPct to rank by |oiDeltaPct| (largest magnitude regardless of direction).
• market oi-change limit: 1–100 (default 20). For deeper than 100 rows, fetch oi-history per instId.
• indicator --bar valid values: 3m 5m 15m 1H 4H 12Hutc 1Dutc 3Dutc 1Wutc — 1m is not supported for indicators (use candles for 1-minute data)
• indicator --limit: 1–100 (only used with returnList, i.e. when a historical series is requested)
• indicator arg order: indicator name before instId — okx market indicator rsi BTC-USDT
• indicator --params: comma-separated, no spaces — --params 5,20. For period-based indicators (ema/ma/wma/rsi/macd/bb/…) omitting --params makes the CLI substitute a default period (EMA/MA/WMA/RSI → 14, MACD → 12,26,9, BB → 20,2) so the table is populated instead of empty; pass --params explicitly to override the default. (CLI-only convenience — the MCP market_get_indicator raw-data path still requires an explicit paramList.)
• indicator no values returned: the CLI never prints nothing — if a query yields no values (e.g. a non-period indicator, or a period indicator with no default), it prints a visible hint: No indicator values returned. This indicator may require a period — try --params (e.g. --params 14).
• BTC-only indicators: ahr999, rainbow — BTC-USDT only
• Unknown indicator name: returns a ValidationError with similar-name suggestions before the API is called — use market_list_indicators / okx market indicator list to see all valid names
• Stock token hours: US stocks trade Mon–Fri ~09:30–16:00 ET; verify live price before acting
• No data returned: instrument may be delisted — verify with okx market instruments
• boll is an alias for bb

Global Notes

• No API key required for any command in this skill
• Rate limit: 20 req / 2 s per IP
• Candle data is sorted newest-first
• vol24h is in base currency (e.g., BTC for BTC-USDT)
• --demo/--live and --profile do not affect market data results via CLI (public endpoints); they only determine the active trading environment context
