OpenTrade CEX Trading

39 API endpoints for centralized exchange trading — market data, public metadata, account management, spot & futures orders, positions, and leverage.

IMPORTANT: This is a CEX (centralized exchange) trading skill. All trades are executed server-side with built-in risk controls — no private key management or transaction signing required.

IMPORTANT: Write operations (place order, close position, set leverage) are protected by a 4-layer risk engine: price deviation check, position limit, rate limit, and balance verification.

CRITICAL — Required Parameters for Orders:

• type (REQUIRED): Order type must always be specified (market, limit, stop_market, take_profit_market). Each type has different parameter requirements.
• hedged (REQUIRED): When placing orders (POST /orders) or closing positions (POST /positions/close), the hedged field is required. If the hedged value is unknown or not provided by the user, you MUST first call GET /position/mode to obtain data.hedged. Once obtained, the value can be reused for subsequent requests on the same symbol and exchange without re-fetching. Using an incorrect hedged value may cause order rejection or affect the wrong position.
• quantity for close position (REQUIRED): When closing a position, you must explicitly provide the quantity to close. 0 is not allowed. Use the actual position size from GET /positions when closing the full position.

CRITICAL — Prefer Contract (Swap) Symbol:

• When /market/metadata returns multiple markets, default to the perpetual/swap symbol (e.g., BTC/USDT:USDT) rather than the spot symbol (e.g., BTC/USDT).
• Only use the spot symbol when the user explicitly requests spot trading.
• Always use symbol field, NOT displaySymbol, when making API calls.

Pre-flight Checks

Every time before running any CEX command, always follow these steps in order:

1. Find or create a .env file in the project root to load the API credentials:

OPEN_TOKEN=your_token_here

Get your API token at: https://www.newsliquid.com/mcp

Security warning: Never commit .env to git (add it to .gitignore) and never expose credentials in logs, screenshots, or chat messages.

2. Set the base URL and auth header:

BASE_URL="https://ai.6551.io"
AUTH_HEADER="Authorization: Bearer $OPEN_TOKEN"

Skill Routing

• For on-chain wallet balances / portfolio → use opentrade-portfolio
• For on-chain market data / smart money signals → use opentrade-market
• For token search / holders / trending → use opentrade-token
• For custodial wallet (BSC/Solana) → use opentrade-wallet
• For transaction broadcasting / gas → use opentrade-gateway
• For CEX trading (spot, futures, leverage, orders, positions) → use this skill (opentrade-cex)

Supported Exchanges

Quickstart

# 1. Get real-time ticker
curl -s "$BASE_URL/open/trader/newsliquid/v1/market/ticker?symbol=BTC/USDT&exchangeId=binance" \
  -H "$AUTH_HEADER"

# 2. Check account balance
curl -s "$BASE_URL/open/trader/newsliquid/v1/account/summary?exchangeId=binance&symbol=BTC/USDT:USDT" \
  -H "$AUTH_HEADER"

# 3. Get position mode (if hedged value is unknown, MUST call before placing orders or closing positions)
curl -s "$BASE_URL/open/trader/newsliquid/v1/position/mode?symbol=BTC/USDT:USDT&exchangeId=binance" \
  -H "$AUTH_HEADER"
# → Returns {"data": {"hedged": false, "info": {"dualSidePosition": false}}, "success": true}

# 4. Place a limit buy order (use hedged value from step 3)
curl -s -X POST "$BASE_URL/open/trader/newsliquid/v1/orders" \
  -H "$AUTH_HEADER" -H "Content-Type: application/json" \
  -d '{"symbol":"BTC/USDT:USDT","side":"buy","type":"limit","quantity":0.001,"price":60000,"exchangeId":"binance","hedged":false}'

# 5. Check open orders
curl -s "$BASE_URL/open/trader/newsliquid/v1/orders/open?exchangeId=binance" \
  -H "$AUTH_HEADER"

# 6. Check current positions
curl -s "$BASE_URL/open/trader/newsliquid/v1/positions?exchangeId=binance" \
  -H "$AUTH_HEADER"

# 7. Close a position (use hedged value from step 3, quantity is required)
curl -s -X POST "$BASE_URL/open/trader/newsliquid/v1/positions/close" \
  -H "$AUTH_HEADER" -H "Content-Type: application/json" \
  -d '{"symbol":"BTC/USDT:USDT","side":"long","quantity":0.001,"exchangeId":"binance","hedged":false}'

Note: Trading pair format follows CCXT standard:

• Spot: BTC/USDT (no colon, no leverage)
• Perpetual futures (swap): BTC/USDT:USDT (with :SETTLE suffix, supports leverage) — default choice for most trading operations

Always use the exact symbol value returned from GET /market/metadata to ensure correct market type. Prefer the contract/swap symbol by default; use spot only when user explicitly requests it.

API Reference

1. Get Market Metadata

获取指定交易对在所有交易所的市场元数据信息（交易对列表、合约类型、杠杆范围、最小下单量等）。

CRITICAL — Symbol Format (CCXT Standard):

Spot trading pairs: BASE/QUOTE format

• Example: BTC/USDT (spot trading, no leverage)
• Characteristics: spot: true, swap: false, contract: false, margin: false

Perpetual futures (swap): BASE/QUOTE:SETTLE format

• Example: BTC/USDT:USDT (USDT-margined perpetual contract)
• Characteristics: spot: false, swap: true, contract: true, margin: true
• The :SETTLE suffix indicates the settlement currency (usually matches QUOTE)

How to distinguish in /market/metadata response:

1. Check the symbol field format:
   • Contains : → Perpetual futures (e.g., BTC/USDT:USDT)
   • No : → Spot (e.g., BTC/USDT)
2. Check boolean flags:
   • spot: true → Spot trading pair
   • swap: true → Perpetual futures
   • contract: true → Any derivative (futures/swap/option)
3. Check type field: "spot", "swap", "future", "option"

IMPORTANT — Use symbol, NOT displaySymbol:

• Always use the symbol field when calling other endpoints (ticker, orders, positions, etc.)
• The displaySymbol field is for display purposes only and may not work correctly in API calls
• Example: Use symbol: "BTC/USDT:USDT" from the response, not displaySymbol

CRITICAL — Prefer Contract (Swap) Symbol by Default:

• When /market/metadata returns multiple markets for the same ticker (e.g., both spot BTC/USDT and swap BTC/USDT:USDT), prioritize the contract/swap symbol (swap: true or contract: true) unless the user explicitly requests spot trading
• Why: Most CEX trading operations (leverage, open/close positions, futures trading) require the contract symbol. Using the spot symbol for these operations will fail or produce unexpected results
• Selection priority (top to bottom):
  1. Perpetual futures (swap: true, symbol has :SETTLE suffix) — default choice
  2. Futures (future: true) — if no swap is available
  3. Spot (spot: true) — only when user explicitly asks for spot trading (e.g., "buy BTC spot", "spot trade")
• User intent signals for spot: "spot", "现货", "spot trading", "buy and hold"
• User intent signals for contract/swap (default): "long", "short", "leverage", "futures", "perpetual", "做多", "做空", "杠杆", "合约", "open position", "close position"
• When in doubt, ask the user: "Do you want to trade spot or perpetual futures?"

This endpoint is protected by the risk engine — orders that deviate too far from market price, exceed position limits, hit rate limits, or lack sufficient balance will be rejected.

CRITICAL — Required Parameters:

• type (REQUIRED): Order type must be explicitly specified. Choose from: market, limit, stop_market, take_profit_market. Each type has different parameter requirements (see Order Types section below).
• hedged (REQUIRED): Hedge mode flag. If the value is unknown, call GET /position/mode first to obtain data.hedged. Once obtained, it can be reused for subsequent orders on the same symbol/exchange.

       {"symbol":"BTC/USDT:USDT","side":"buy","type":"market","quantity":0.1,"exchangeId":"binance"}
5. opentrade-cex  GET /orders/open                                       → confirm order status

Data handoff:

• last price from step 1 → helps user decide order type (market vs limit)
• available balance from step 2 → validates user can afford the order
• Market info from step 3 → confirms pair exists and shows limits

Workflow B: CEX Futures Trading

User: "Open a 10x long on ETH with $1000"

1. opentrade-cex  GET /market/ticker?symbol=ETH/USDT&exchangeId=binance  → check ETH price
2. opentrade-cex  GET /account/summary?exchangeId=binance&symbol=ETH/USDT:USDT&accountType=swap  → check margin balance
3. opentrade-cex  GET /leverage/current?symbol=ETH/USDT:USDT&exchangeId=binance  → check current leverage
4. opentrade-cex  PUT /leverage/current                       → set leverage to 10x (if needed)
       {"symbol":"ETH/USDT:USDT","leverage":10,"exchangeId":"binance"}
5. opentrade-cex  GET /position/mode?symbol=ETH/USDT:USDT&exchangeId=binance  → get hedged value (if unknown)
6. opentrade-cex  POST /orders                                → open long position (use hedged from step 5)
       {"symbol":"ETH/USDT:USDT","side":"buy","type":"market","quantity":<calculated>,"exchangeId":"binance","hedged":false}
7. opentrade-cex  GET /positions                              → verify position opened

Data handoff:

• last price from step 1 → calculate quantity: $1000 / ETH_price
• Leverage 10x means only $100 margin needed for $1000 position
• data.hedged from step 5 → pass to order request in step 6

2. [opentrade-market]     GET /market/price (on-chain)               → DEX price
3. Compare prices → identify arbitrage opportunity
4a. CEX cheaper → opentrade-cex POST /orders (CEX buy) + [opentrade-dex-swap] (DEX sell)
4b. DEX cheaper → [opentrade-dex-swap] (DEX buy) + opentrade-cex POST /orders (CEX sell)
5. Confirm both sides filled → calculate profit

Workflow E: CEX Hedge + DEX Spot Holdings

User: "Hedge my on-chain ETH holdings with a CEX short"

3. opentrade-cex   GET /market/metadata                       → check if listed on CEX
4. If CEX listed → opentrade-cex POST /orders                 → trade on CEX (lower fees)
   If not listed → [opentrade-dex-swap]                              → trade on DEX

4. [opentrade-portfolio]  Get on-chain wallet balances               → DEX holdings
5. Combine and present unified portfolio report

Operation Flow

Step 1: Identify Intent

Step 2: Collect Parameters

• Missing exchangeId → ask user which exchange (e.g., binance, bybit, okx, hyperliquid)
• Missing symbol → ask user which trading pair; format as CCXT standard (e.g., BTC/USDT for spot, BTC/USDT:USDT for perpetual)
• Missing side → ask user: buy or sell?
• Missing order type → suggest market for immediate execution, limit for price control
• Missing quantity → ask user; for futures, help calculate based on notional value and leverage. For POST /positions/close, quantity is mandatory and must be greater than 0.
• Missing price → required for limit orders; call GET /market/ticker to show current price as reference
• Missing leverage → check current setting with GET /leverage/current; suggest 1x-10x for beginners

Step 3: Execute & Display

• Run the API call
• Parse JSON response
• Display human-readable summary with prices, quantities, P&L in friendly format
• For order creation: show order ID, pair, side, type, quantity, price, status
• For positions: show pair, side, entry/mark price, P&L, leverage
• For account: show total/available balance, unrealized P&L

Step 4: Suggest Next Steps

Present conversationally — never expose endpoint paths to the user.

Risk Engine Notes

All risk-controlled endpoints (marked with "Risk: Yes" in Command Index) pass through a 4-layer risk engine before execution:

What happens when risk check fails:

• The API returns an error with a description of which rule was triggered
• The order/action is NOT executed
• Display the reason to the user clearly (e.g., "Order rejected: price deviates 15% from market price, max allowed is 10%")
• Suggest corrective action (adjust price, reduce quantity, wait and retry, etc.)

Risk engine behavior:

• Rules are checked in priority order (rate limit → price deviation → position limit → balance check)
• First failure stops the chain — remaining rules are not checked
• The risk engine uses a fail-open strategy: if market data or Redis is unavailable, the check passes (prioritizing availability)

Input / Output Examples

User says: "What's the BTC price on Binance?"

curl -s "$BASE_URL/open/trader/newsliquid/v1/market/ticker?symbol=BTC/USDT&exchangeId=binance" -H "$AUTH_HEADER"
# → BTC/USDT: $67,890.50 (Bid: $67,889 | Ask: $67,891)

User says: "Buy 0.01 BTC at $65,000"

# Step 1: Get position mode (if hedged value is unknown)
curl -s "$BASE_URL/open/trader/newsliquid/v1/position/mode?symbol=BTC/USDT:USDT&exchangeId=binance" -H "$AUTH_HEADER"
# → {"data": {"hedged": false, "info": {"dualSidePosition": false}}, "success": true}

# Step 2: Place order with hedged value from step 1
curl -s -X POST "$BASE_URL/open/trader/newsliquid/v1/orders" \
  -H "$AUTH_HEADER" -H "Content-Type: application/json" \
  -d '{"symbol":"BTC/USDT:USDT","side":"buy","type":"limit","quantity":0.01,"price":65000,"exchangeId":"binance","hedged":false}'
# → Order placed! Buy 0.01 BTC @ $65,000 (Limit) — ID: 123456789

User says: "Close my BTC position"

# Step 1: Get position mode (if hedged value is unknown)
curl -s "$BASE_URL/open/trader/newsliquid/v1/position/mode?symbol=BTC/USDT:USDT&exchangeId=binance" -H "$AUTH_HEADER"
# → {"data": {"hedged": false, "info": {"dualSidePosition": false}}, "success": true}

# Step 2: Close position with hedged value from step 1
# Use the actual position size from GET /positions when closing the full position
curl -s -X POST "$BASE_URL/open/trader/newsliquid/v1/positions/close" \
  -H "$AUTH_HEADER" -H "Content-Type: application/json" \
  -d '{"symbol":"BTC/USDT:USDT","side":"long","quantity":0.01,"exchangeId":"binance","hedged":false}'
# → Position closed! Realized P&L: +$25.00

User says: "Set my ETH leverage to 20x"

curl -s -X PUT "$BASE_URL/open/trader/newsliquid/v1/leverage/current" \
  -H "$AUTH_HEADER" -H "Content-Type: application/json" \
  -d '{"symbol":"ETH/USDT:USDT","leverage":20,"exchangeId":"binance"}'
# → Leverage updated! ETH/USDT:USDT: 20x

Edge Cases

• Risk engine rejects order: Display the rejection reason clearly. Common causes: price too far from market (>10%), position too large, rate limited, insufficient balance. Suggest the user adjust parameters and retry.
• Insufficient balance: Check balance with GET /account/summary first. For futures, consider leverage — required margin = order value / leverage.
• Rate limited: If 30+ requests in 1 minute, wait 60 seconds before retrying. Inform the user about the cooldown.
• Close position quantity missing or zero: For POST /positions/close, quantity must be explicitly provided and must be greater than 0. To close the full position, call GET /positions first and use the actual current position size.
• Position mode conflict: Cannot switch position mode while holding open positions. Close all positions first.
• Leverage change with open positions: Some exchanges restrict leverage changes when positions are open. Close positions or reduce size first.
• Order quantity precision: Use GET /market/metadata to check amountMin and costMin. Ensure order meets minimum requirements.
• Minimum notional: Orders below the minimum cost (e.g., $5 costMin) will be rejected by the exchange.
• Network error: Retry once, then prompt user to try again later.
• Region restriction (error code 50125 or 80001): Do NOT show the raw error code to the user. Instead, display: Service is not available in your region. Please switch to a supported region and try again.

Amount Display Rules

• CEX amounts use standard units (e.g., 0.1 BTC, 100 USDT) — NOT minimal units like DEX
• Always show currency symbol alongside amounts
• Format large numbers with commas (e.g., $67,500.50)
• Show P&L with sign and color hint: positive (+$250.00), negative (-$100.00)
• Show percentage changes with sign (e.g., +1.89%, -0.52%)
• Leverage shown as multiplier (e.g., 10x, 20x)

Global Notes

• All endpoints require Authorization: Bearer <token> header
• Supported exchanges: binance, bybit, okx, hyperliquid, aster
• Trading pair format follows CCXT standard:
  • Spot: BTC/USDT (no colon suffix)
    • Characteristics: spot: true, swap: false, contract: false, leverageMax: 1
    • Use for spot trading without leverage
  • Perpetual futures (swap): BTC/USDT:USDT (with :SETTLE suffix)
    • Characteristics: spot: false, swap: true, contract: true, leverageMax: 125
    • The :SETTLE suffix indicates settlement currency (usually matches quote currency)
    • Use for leveraged perpetual contract trading
  • Always use the exact symbol value from GET /market/metadata response to ensure correct market type
  • Always use symbol, NOT displaySymbol when calling API endpoints (displaySymbol is for display only)
  • Default to contract (swap) symbol when multiple markets exist for the same ticker — only use spot when user explicitly asks for spot trading
  • Quick check: If symbol contains : → it's a perpetual futures contract; no : → it's spot
• The API routes through the CEX gateway with built-in risk controls — trades execute server-side
• No private keys or transaction signing involved — this is CEX trading via API
• CEX uses standard amount units (e.g., 0.1 BTC), unlike DEX which uses minimal units (wei/lamports)
• Numeric values in request bodies use native types (numbers, not strings): "quantity": 0.01, "price": 65000.00
• Risk-controlled endpoints may reject requests — always display the rejection reason to the user
• Query parameters go in the URL, body parameters go in JSON request body
• Each API request consumes 1 quota unit (shown in usage field of response)
• Success response: {"success": true, "data": {...}, "usage": {"cost": 1, "quota": 99}}
• Error response (upstream): {"success": false, "code": "INVALID_REQUEST", "error": "message"}
• Error response (gateway): {"code": 400, "message": "error message", "error": "details"}
• The skill uses the same OPEN_TOKEN as all other opentrade skills — no additional configuration needed
