6DuckLearn provenance: Official OKX skill from https://github.com/okx/agent-skills. Curated here means source-reviewed by 6DuckLearn; it is not an endorsement of a strategy, asset, return claim, or suitability.

Financial safety boundary: Never request secrets in chat. Before any external API call or action that places, cancels, or amends an order; changes leverage; transfers funds; creates or stops a bot; subscribes to or redeems an earn product; or signs/broadcasts a transaction, show the exact live/demo profile, instrument, side, size, price constraints, fees, and worst-case loss, then obtain explicit user approval. Default to read-only or demo mode when uncertain. Treat all analysis as research, not investment advice.

OKX CEX Portfolio & Account CLI

Account balance, positions, P&L, bills, fees, and fund transfers on OKX exchange. 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   # select site -> follow browser OAuth flow
    
  3. Test with demo mode (simulated trading, no real funds):
    okx --demo account balance
    

Security: NEVER accept credentials in chat. Guide users to okx config init for setup.

Credential & Profile Check

Run this check before any authenticated command. The auth method is detected during preflight Step 2 and remembered for the session.

Step A — Verify credentials

Check both sources (see preflight Step 2 for the decision table). okx auth status --json alone is insufficient — its apiKey field is always false and does NOT reflect the TOML config.

okx config show --json      # authoritative for API-key presence
okx auth status --json      # authoritative for OAuth session state

Branch in this order — first match wins:

  • config show has any profile with a non-empty api_keyAPI Key mode. Proceed to Step B.
  • No API-key profile AND auth status returns "status": "logged_in"OAuth mode. Proceed to Step B.
  • No API-key profile AND auth status returns "status": "pending" — login in progress, wait.
  • No API-key profile AND auth status returns "status": "not_logged_in"stop all operations, load okx-cex-auth skill and follow login steps, wait for completion.

Step B — Confirm trading mode

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
  2. Current message has no explicit declaration → check conversation context for a previous choice:
    • Found → reuse it, inform user
    • Not found → ask: "Live (实盘) or Demo (模拟盘)?" — wait for answer before proceeding

How to apply the mode depends on auth method (detected in Step A):

Auth method Live (实盘) Demo (模拟盘)
API Key --profile <live-profile> --profile <demo-profile>
OAuth (no flag needed, live is default) --demo
  • API Key users: run okx config show --json to discover available profile names and their demo settings. Use --profile <name> to select the correct one.
  • OAuth users: omit flags for live trading; add --demo for simulated trading. Do not use --profile to switch modes.

Handling Authentication Errors

Authentication error (error contains "401", "Session expired", or "Run okx auth login first"):

  1. Stop immediately — do not retry the same command
  2. Inform the user: "Authentication failed. Your session may have expired."
  3. Load okx-cex-auth skill and follow the re-authentication steps
  4. After successful re-authentication, retry the original command

Demo vs Live Mode

Mode Funds API Key param OAuth param
实盘 (live) Real funds --profile <live-profile> (default, no flag)
模拟盘 (demo) Simulated funds --profile <demo-profile> --demo
# API Key user
okx --profile okx-prod  account balance     # 实盘
okx --profile okx-demo  account balance     # 模拟盘

# OAuth user
okx account balance                          # 实盘 (default)
okx --demo account balance                   # 模拟盘

Rules:

  • Read commands (balance, positions, bills, etc.): always state which mode was used
  • Write commands (transfer, set-position-mode): mode must be confirmed before execution (see "Credential & Profile Check" Step B); transfer especially — wrong mode means wrong account
  • Every response after a command must append: [mode: live] or [mode: demo]

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 (this skill)
  • For regular spot/swap/futures/algo orders → use okx-cex-trade
  • For grid and DCA trading bots → use okx-cex-bot

3. okx-cex-market    okx market ticker BTC-USDT-SWAP        → current price reference

Operation Flow

Step 0 — Credential & Profile Check

Before any authenticated command: see Credential & Profile Check. Determine auth method and trading mode before executing.

After every command result: append [mode: live] or [mode: demo] to the response

Step 1: Identify account action

  • Check all balances at once → okx account balance-all (trading + funding + valuation in one call; recommended for "总资产 / net worth / all balances")
  • Check balance → okx account balance (trading equity only) or okx account asset-balance (funding balances) or okx account asset-balance --valuation (total across all accounts in USDT)
  • View open positions → okx account positions
  • View closed positions + PnL → okx account positions-history
  • View transaction history → okx account bills
  • Check fee tier → okx account fees
  • Check account settings → okx account config
  • Calculate order size → okx account max-size or okx account max-avail-size
  • Check withdrawal limit → okx account max-withdrawal
  • Transfer funds → okx account transfer
  • Change position mode → okx account set-position-mode

Step 2: Run read commands immediately — confirm profile (Step 0) then writes

Read commands (1–10): run immediately, no confirmation needed.

  • ccy filter: use currency symbol like USDT, BTC, ETH
  • --instType for fees/positions: SPOT, SWAP, FUTURES, OPTION
  • --archive for bills: access older records beyond the default window
  • --tdMode for max-size: cash (spot), cross, or isolated

Write commands (11–12): confirm once before executing.

  • set-position-mode: confirm mode (net = one-directional, long_short_mode = hedge mode); switching may affect open positions
  • transfer: confirm --ccy, --amt, --from, --to (account types: 6=funding, 18=trading); verify source balance first

Step 3: Verify after writes

  • After set-position-mode: run okx account config to confirm posMode updated
  • After transfer: run okx account balance and okx account asset-balance to confirm balances updated

CLI Command Reference

Balance All — One-Shot Aggregate Snapshot

okx account balance-all [ccy] [--accounts trading,funding] [--no-valuation] [--no-aggregate] [--valuationCcy <ccy>] [--json]
Param Required Default Description
ccy No - Filter by currency (comma-separated). Applied to trading + funding queries only.
--accounts No trading,funding Comma-separated accounts to query
--no-valuation No - Skip cross-account valuation (default: valuation included)
--no-aggregate No - Force the direct parallel path instead of the server aggregate. Use when you need the per-account valuation breakdown, or a non-USD --valuationCcy (the aggregate path denominates valuation in USD).
--valuationCcy No USDT Denomination currency for valuation

This command calls a server-side aggregate endpoint first and automatically falls back to direct parallel queries when it is unavailable; the output contract is identical either way.

Returns { trading, funding, valuation, meta }. Each section has available: boolean:

  • trading: totalEq, adjEq, details[] (per-currency)
  • funding: details[] (per-currency ccy, bal, availBal, frozenBal)
  • valuation: valuationCcy, totalBal, details[] (per-account breakdown is only populated on the parallel path; use --no-aggregate to force it)
  • meta: requestedAt (ISO 8601), elapsedMs, partialFailure, source (aggregate or fallback), site

When --json is NOT set: prints [PARTIAL] banner if meta.partialFailure=true, followed by three sections (Trading / Funding / Valuation), then a [source: ...] footer showing which path served the data. Failed sections show [ERROR: <msg>].


Account Balance — Trading Account

okx account balance [ccy] [--json]
Param Required Default Description
ccy No - Filter to a single currency (e.g., USDT)

Returns table: currency, equity, available, frozen. Only shows currencies with balance > 0.


Asset Balance — Funding Account

okx account asset-balance [ccy] [--valuation] [--valuationCcy <ccy>] [--json]
Param Required Default Description

--valuation No false Also show total asset valuation across all account types (trading/funding/earn)
--valuationCcy No USDT Currency in which to denominate the total asset valuation (e.g., USDT, BTC). Only used when --valuation is set.

Returns: ccy, bal, availBal, frozenBal. Only shows currencies with balance > 0.

With --valuation: additionally prints a valuation summary table with totalBal and per-account-type breakdown (classic/earn/funding/trading). The numbers are denominated in --valuationCcy (default USDT).

Important: ccy (balance filter) and --valuationCcy (valuation denomination) are independent parameters — ccy=BTC filters the balance list to BTC rows but does NOT change the valuation currency; set --valuationCcy BTC explicitly for BTC-denominated totals.


Positions — Open Positions

okx account positions [--instType <type>] [--instId <id>] [--json]
Param Required Default Description
--instType No - Filter: SWAP, FUTURES, OPTION

Returns: transId, ccy, amt.


MCP Tool Reference

Tool Description
account_get_balance_all One-shot snapshot of trading + funding (+ valuation), served by a server-side aggregate endpoint with automatic fallback to parallel queries. Use showValuation=true (default) to include cross-account totals; valuationCcy='USDT' by default. Set preferParallel=true to force the parallel path (per-account valuation breakdown / non-USD valuation). Prefer over calling account_get_balance + account_get_asset_balance separately.
account_get_balance Trading account balance
account_get_asset_balance Funding account balance. Use showValuation=true to include total asset valuation across trading/funding/earn accounts. Use valuationCcy (default "USDT") to set the denomination for the valuation total — e.g. valuationCcy="BTC" returns the total in BTC.
account_get_positions Open positions
account_get_positions_history Closed position history
account_get_bills Account bills (recent)
account_get_bills_archive Account bills (archive)
account_get_trade_fee Trading fee tier

"How much USDT do I have?"

okx account balance USDT
# → currency: USDT | equity: 5000.00 | available: 4500.00 | frozen: 500.00

"Show all my open positions"

okx account positions
# → table: instId, instType, side, pos, avgPx, upl, lever

okx account positions-history
# → table: instId, direction, openAvgPx, closeAvgPx, realizedPnl, uTime

"Show my recent account activity"

okx account bills --limit 20
# → table: billId, instId, type, ccy, balChg, bal, ts

"What are my trading fees for SWAP?"

okx account fees --instType SWAP
# → level: VIP1 | maker: -0.0001 | taker: 0.0005

"How much BTC can I buy in cross margin?"

okx account max-size --instId BTC-USDT-SWAP --tdMode cross
# → instId: BTC-USDT-SWAP | maxBuy: 12.5 | maxSell: 12.5

"Transfer 200 USDT from funding to trading"

okx account transfer --ccy USDT --amt 200 --from 6 --to 18
# → Transfer: TXN123456 (USDT 200)

Where Can the Money Live?

OKX splits assets across multiple sub-accounts. The --valuation breakdown maps directly:

Account type details key Used for Check with
Trading (unified) trading Spot, margin, swap, futures, options okx account balance or details.trading in --valuation
Funding funding Deposits/withdrawals, idle funds okx account asset-balance or details.funding in --valuation
Earn earn Simple earn, staking, savings details.earn in --valuation
Classic classic Classic account (legacy, less common) details.classic in --valuation

Typical flow when user says "I have X USDT but can't trade":

  1. okx account asset-balance --valuation → look at each details.* field
  2. If details.funding is large and details.trading is small → the funds are in the funding account
  3. Transfer: okx account transfer --ccy USDT --amt <n> --from 6 --to 18
  4. Confirm: okx account balance USDT → equity should now reflect the transferred amount

Edge Cases

  • No balance shown: balance is filtered to > 0 — if nothing shows, all currencies have zero balance
  • Positions command returns empty: no open contracts; spot holdings are not shown here (use account balance)
  • bills --archive: required for transactions older than 7 days (default window); may be slower
  • set-position-mode: cannot switch to net if you have both long and short positions on the same instrument
  • transfer --from/--to codes: 6=funding account, 18=trading account; other values exist for sub-account flows
  • max-size vs max-avail-size: max-size is the theoretical maximum; max-avail-size accounts for existing orders and reserved margin
  • Demo mode: okx --demo account balance (OAuth) or okx --profile <demo-profile> account balance (API Key) shows simulated balances, not real funds

Global Notes

  • All write commands require valid credentials (OAuth session or API key in ~/.okx/config.toml)
  • Auth method and trading mode are determined in "Credential & Profile Check"; see that section for parameter rules
  • Every command result includes a [mode: live] or [mode: demo] tag for audit reference
  • --json returns the raw OKX API v5 response by default. Add --env to wrap the output as {"env": "<live|demo>", "profile": "<name>", "data": <response>}
  • Rate limit: 10 requests per 2 seconds for account endpoints
  • Positions shown are for the unified trading account; funding account assets are separate
  • Account types: 6=Funding Account (deposits/withdrawals), 18=Unified Trading Account (spot + derivatives)
