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 → INLINECODE1
• Place / cancel orders → INLINECODE2
• Grid / DCA bots → INLINECODE3

Preflight

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

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"}.

Operation Flow

Step 1 — Identify data type and load reference

User intent	Reference to load
Price, candles, order book, recent trades	INLINECODE33
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 | | 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
• indicator arg order: indicator name before instId — INLINECODE61
• indicator --params: comma-separated, no spaces — INLINECODE63
• BTC-only indicators: ahr999, rainbow — BTC-USDT only
• Unknown indicator name: the API returns empty data silently — run okx market indicator list to confirm a name is supported before use
• 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 INLINECODE67
• boll is an alias for INLINECODE69

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
• INLINECODE70 is in base currency (e.g., BTC for BTC-USDT)
• INLINECODE71 and --demo/--live do not affect market data results via CLI (public endpoints); they only determine the active trading environment context
• When calling market MCP tools directly, pass demo: true to explicitly query simulated trading market data; the default is always live market data regardless of server demo mode
