OKX CEX Trading CLI

Spot, perpetual swap, delivery futures, and options order management on OKX exchange. Place, cancel, amend, and monitor orders; query option chains and Greeks; set take-profit/stop-loss and trailing stops; manage leverage and positions. Requires API credentials.

Preflight

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

Prerequisites

1. Install okx CLI:

   npm install -g @okx_ai/okx-trade-cli
   

2. Configure credentials:

   okx config init
   

   Or set environment variables:

   export OKX_API_KEY=your_key
   export OKX_SECRET_KEY=your_secret
   export OKX_PASSPHRASE=your_passphrase
   

3. Test with demo mode (simulated trading, no real funds):

   okx --profile demo spot orders
   

Credential & Profile Check

Run this check before any authenticated command.

Step A — Verify credentials

okx config show       # verify configuration status (output is masked)

• If the command returns an error or shows no configuration: stop all operations, guide the user to run okx config init, and wait for setup to complete before retrying.
• If credentials are configured: proceed to Step B.

Step B — Confirm profile (required)

--profile is required for all authenticated commands. Never add a profile implicitly.

Value	Mode	Funds
live	实盘	Real funds
demo	模拟盘	Simulated funds

Resolution rules:

1. Current message intent is clear (e.g. "real" / "实盘" / "live" → live; "test" / "模拟" / "demo" → demo) → use it and inform the user: "Using --profile live (实盘)" or "Using --profile demo (模拟盘)"
2. Current message has no explicit declaration → check conversation context for a previous profile:
   • Found → use it, inform user: "Continuing with --profile live (实盘) from earlier"
   • Not found → ask: "Live (实盘) or Demo (模拟盘)?" — wait for answer before proceeding

Handling 401 Authentication Errors

If any command returns a 401 / authentication error:

1. Stop immediately — do not retry the same command
2. Inform the user: "Authentication failed (401). Your API credentials may be invalid or expired."
3. Guide the user to update credentials by editing the file directly with their local editor:

   ~/.okx/config.toml
   

   Update the fields api_key, secret_key, passphrase under the relevant profile. Do NOT paste the new credentials into chat.
4. After the user confirms the file is updated, run okx config show to verify (output is masked)
5. Only then retry the original operation

Demo vs Live Mode

Profile is the single control for 实盘/模拟盘 switching:

--profile	Mode	Funds
live	实盘	Real money — irreversible
demo	模拟盘	Simulated — no real funds

Rules:

1. --profile is required on every authenticated command — determined in "Credential & Profile Check" Step B
2. Every response after a command must append: [profile: live] or [profile: demo]
3. Do not use the --demo flag for mode switching — use --profile instead

Skill Routing

• For market data (prices, charts, depth, funding rates) → use okx-cex-market
• For account balance, P&L, positions, fees, transfers → use okx-cex-portfolio
• For regular spot/swap/futures/options/algo orders → use okx-cex-trade (this skill)
• For grid and DCA trading bots → use okx-cex-bot

Sz Handling for Derivatives

⚠ CRITICAL: Always verify contract face value before placing orders

Before placing any SWAP/FUTURES/OPTION order, call market_get_instruments to get ctVal (contract face value). Do NOT assume contract sizes — they vary by instrument (e.g. ETH-USDT-SWAP = 0.1 ETH/contract, BTC-USDT-SWAP = 0.01 BTC/contract).

Use ctVal to:

• Calculate the correct number of contracts from user's intended position size
• Verify margin requirements before submitting the order
• Show the user the actual position value: sz × ctVal × price

SWAP and FUTURES orders

Three tgtCcy modes for USDT-denominated sizing:

--tgtCcy	sz meaning	Conversion formula	Example: "500U" at 10x lever
base_ccy (default)	contract count	no conversion	500 contracts
quote_ccy	USDT notional value	floor(sz / (ctVal * lastPx))	500 USDT notional
margin	USDT margin cost	floor(sz * lever / (ctVal * lastPx))	500 USDT margin = 5000 USDT notional

When user specifies a USDT amount (e.g. "200U", "500 USDT", "$1000"): → AMBIGUOUS — this could mean notional value OR margin cost. You MUST ask: "您输入的 500U 是名义价值（notional value）还是保证金成本（margin cost）？名义价值模式下 500U 直接买入 500U 等值合约；保证金模式下 500U 保证金以当前杠杆计算，实际仓位 = 500U × 杠杆倍数。" Wait for the user's answer before continuing.

• If notional value → use --tgtCcy quote_ccy
• If margin cost → use --tgtCcy margin

When user specifies contracts (e.g. "2 张", "5 contracts"): → First verify ctVal via market_get_instruments, then use --sz with the contract count. Confirm with user: "X contracts = X × ctVal underlying, total value ≈ $Y".

When user gives a plain number with no unit (for swap/futures): → Ambiguous — ask before proceeding: "您输入的 X 是合约张数、USDT 名义价值还是 USDT 保证金成本？" Wait for the user's answer before continuing.

⚠ Inverse contracts (*-USD-SWAP, *-USD-YYMMDD): tgtCcy=quote_ccy and tgtCcy=margin also work (note: quote_ccy = USD, not USDT, for inverse instruments). Always warn: "This is an inverse contract. Margin and P&L are settled in BTC, not USDT."

Option orders

When the user specifies a USDT amount for options, use --tgtCcy quote_ccy (notional) or --tgtCcy margin (margin cost) and pass the amount as --sz. The system automatically converts to contracts. Note: option contracts typically have large face values (e.g. ctVal=1 BTC ≈ $84,000), so the minimum USDT amount for 1 contract is high. For option sellers (cross/isolated tdMode), margin mode accounts for leverage automatically.

Operation Flow

Step 0 — Credential & Profile Check

Before any authenticated command: see Credential & Profile Check. Determine profile (live or demo) before executing.

After every command result: append [profile: live] or [profile: demo].

Step 1 — Identify instrument type and action

Spot (instId format: BTC-USDT):

• Place/cancel/amend order → okx spot place/cancel/amend
• TP/SL conditional → okx spot algo place/amend/cancel
• Trailing stop → okx spot algo trail
• Query → okx spot orders/get/fills/algo orders

Swap/Perpetual (instId format: BTC-USDT-SWAP):

• Place/cancel/amend order → okx swap place/cancel/amend
• Close position → okx swap close
• Leverage → okx swap leverage / okx swap get-leverage
• TP/SL conditional → okx swap algo place/amend/cancel
• Trailing stop → okx swap algo trail
• Query → okx swap positions/orders/get/fills/get-leverage/algo orders

Futures/Delivery (instId format: BTC-USDT-<YYMMDD>):

• Place/cancel/amend order → okx futures place/cancel/amend
• Close position → okx futures close
• Leverage → okx futures leverage / okx futures get-leverage
• TP/SL conditional → okx futures algo place/amend/cancel
• Trailing stop → okx futures algo trail
• Query → okx futures orders/positions/fills/get/get-leverage/algo orders

Options (instId format: BTC-USD-250328-95000-C or ...-P):

• Step 1 (required): find valid instId → okx option instruments --uly BTC-USD
• Step 2 (recommended): check IV and Greeks → okx option greeks --uly BTC-USD
• Place/cancel/amend → okx option place/cancel/amend
• Batch cancel → okx option batch-cancel --orders '[...]'
• Query → okx option orders/get/positions/fills
• tdMode: cash for buyers; cross or isolated for sellers

For cross-skill workflows and step-by-step examples, read {baseDir}/references/workflows.md.

Step 2 — Confirm profile, then confirm write parameters

Read commands (orders, positions, fills, get, get-leverage, algo orders): run immediately.

• --history flag: defaults to active/open; use --history only if user explicitly asks for history
• --ordType for algo: conditional = single TP or SL; oco = both TP and SL together
• --tdMode for swap/futures: cross or isolated; spot always uses cash (set automatically)
• --posSide for hedge mode: long or short; omit in net mode

Write commands (place, cancel, amend, close, leverage, algo): confirm the key order details once before executing:

• Spot place: confirm --instId, --side, --ordType, --sz (and --tgtCcy quote_ccy if quote-currency amount)
• Swap/Futures place: confirm --instId, --side, --sz, --tdMode, and explicitly confirm order mode when user specifies a USDT amount: --tgtCcy quote_ccy (notional value, sz = position value) or --tgtCcy margin (margin cost, actual position = sz * leverage). Always state which mode is being used.
• Option place: confirm --instId, --side, --sz, --tdMode (and --tgtCcy quote_ccy or --tgtCcy margin if USDT amount — system auto-converts); do NOT attach TP/SL
• Swap/Futures close: confirm --instId, --mgnMode, --posSide
• Leverage: confirm new leverage and impact on existing positions
• Algo place (TP/SL): confirm trigger prices; use --tpOrdPx=-1 for market execution
• Algo trail: confirm --callbackRatio (e.g., 0.02 = 2%) or --callbackSpread

For full parameter details per command, read the relevant reference file.

Step 3 — Verify after writes

• After spot place: run okx spot orders to confirm order is live or okx spot fills if market order
• After swap place: run okx swap orders or okx swap positions to confirm
• After swap close: run okx swap positions to confirm position size is 0
• After futures place: run okx futures orders or okx futures positions to confirm
• After futures close: run okx futures positions to confirm position size is 0
• After spot algo place/trail: run okx spot algo orders to confirm algo is active
• After swap algo place/trail: run okx swap algo orders to confirm algo is active
• After futures algo place/trail: run okx futures algo orders to confirm algo is active
• After cancel: run okx spot orders / okx swap orders / okx futures orders to confirm order is gone

Global Notes

• All write commands require valid credentials in ~/.okx/config.toml or env vars
• --profile <name> is required for all authenticated commands
• --json returns the raw OKX API v5 response by default. Add --env to wrap the output as {"env": "<live|demo>", "profile": "<name>", "data": <response>} — useful when you need to know the active environment and credential profile
• Rate limit: 60 order operations per 2 seconds per UID
• Batch operations (batch cancel, batch amend) are available via MCP tools directly if needed
• Position mode (net vs long_short_mode) affects whether --posSide is required
• Network errors: If commands fail with a connection error, prompt user to check VPN: curl -I https://www.okx.com

For MCP tool reference, output conventions, and order amount safety rules, read {baseDir}/references/templates.md.
