# OpenTrade CEX Trading

29 API endpoints for centralized exchange trading — market data, account management, spot & futures orders, positions, leverage, and wallet agent.

> **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, edit order, close position, set leverage) are protected by a 4-layer risk engine: price deviation check, position limit, rate limit, and balance verification.

## 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:
  ```bash
  OPEN_TOKEN=your_token_here
  ```

  Get your API token at: https://6551.io/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:
  ```bash
  BASE_URL="https://ai.6551.io"
  AUTH_HEADER="Authorization: Bearer $OPEN_TOKEN"
  ```

## Skill Routing

- For DEX swaps / on-chain token exchange → use `opentrade-dex-swap`
- 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`)

## Cross-Skill Workflows

### Workflow A: CEX Spot Trading

> User: "Buy 0.1 BTC on Binance"

```
1. opentrade-cex  GET /market/ticker?symbol=BTC/USDT&exchangeId=binance  → check current price
2. opentrade-cex  GET /account/summary?exchangeId=binance                → verify available balance
3. opentrade-cex  GET /market/metadata?ticker=BTC                        → confirm pair info/limits
4. opentrade-cex  POST /orders                                           → place order
       {"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  POST /orders                                → open long position
       {"symbol":"ETH/USDT:USDT","side":"buy","type":"market","quantity":<calculated>,"exchangeId":"binance"}
6. 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

## Operation Flow

### Step 1: Identify Intent

| User wants to... | Action |
|---|---|
| Check CEX market price | `GET /market/ticker` |
| View K-line / chart data | `GET /market/klines` |
| Check account balance | `GET /account/summary` or `GET /account/spots` |
| Place a buy/sell order | `POST /orders` |
| Modify an existing order | `PUT /orders/edit` |
| Cancel an order | `DELETE /orders/:orderId` |
| View open orders | `GET /orders/open` |
| View closed orders | `GET /orders/closed` |
| Check current positions | `GET /positions` |
| Close a position | `POST /positions/close` |
| Set leverage | `PUT /leverage/current` |
| Check leverage / margin | `GET /leverage/current`, `GET /margin/mode` |
| View trade history | `GET /trades/history` |
| Manage wallet agents | `POST/GET/PUT /walletagent/*` |

### 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
- **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

| Just completed | Suggest |
|---|---|
| Checked ticker | 1. Place an order 2. View K-line for trend analysis |
| Checked balance | 1. Place an order 2. Check positions |
| Placed order | 1. Check open orders 2. View positions 3. Set stop-loss |
| Order filled | 1. View positions 2. Set take-profit/stop-loss |
| Position opened | 1. Monitor with ticker 2. Set stop-loss order 3. Close position |
| Position closed | 1. Check realized P&L in trade history 2. Check updated balance |
| Set leverage | 1. Place an order 2. Check position limits |

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:

| Rule | Name | Trigger | Default Threshold |
|---|---|---|---|
| 1 | Price Deviation Check | Limit orders | Max 10% deviation from market price |
| 2 | Position Size Limit | Order creation, position close | Single: 20% of balance, Total: 80% of balance |
| 3 | Rate Limit | All risk-controlled endpoints | 30 requests per minute |
| 4 | Balance Check | Order creation | Min 5% balance reserve |

**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?"

```bash
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"

```bash
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"}'
# → Order placed! Buy 0.01 BTC @ $65,000 (Limit) — ID: 123456789
```

**User says:** "Close my BTC position"

```bash
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,"exchangeId":"binance"}'
# → Position closed! Realized P&L: +$25.00
```

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

```bash
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.
- **Invalid trading pair**: Call `GET /market/metadata` to verify the symbol exists on the exchange.
- **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**: `BTC/USDT` for spot, `BTC/USDT:USDT` for USDT perpetual contracts
- 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
- Wallet Agent feature only supports `aster` and `hyperliquid` exchanges
- 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
