# Phemex Trading

Trade on Phemex via the phemex-cli tool. Supports USDT-M futures, Coin-M futures, and Spot markets.

## What's New in v1.2.0

1. **`list_symbols` tool** — Discover all available trading pairs, filtered by contract type. No more guessing symbol names.
2. **Config file (`~/.phemexrc`)** — Store API credentials persistently. No need to `export` env vars every session.
3. **`--help` for every tool** — Run `phemex-cli <tool> --help` to see parameters, defaults, and usage examples inline.
4. **Friendly field names** — API field suffixes (`closeRp`, `fundingRateRr`) are mapped to readable names (`closePrice`, `fundingRate`). Use `--raw` to get the original names.
5. **Enhanced error messages** — Errors now include `suggestion` and `tip` fields with actionable guidance instead of raw API codes.

## Before you start

Ensure you have the latest version installed:

```bash
npm install -g phemex-trade-mcp@latest
```

## How to call tools

```bash
phemex-cli <tool_name> --param1 value1 --param2 value2
```

Or with JSON args:

```bash
phemex-cli <tool_name> '{"param1":"value1","param2":"value2"}'
```

Output is always JSON. Credentials are loaded from environment variables or `~/.phemexrc` (see Setup).

### Tool help

Every tool supports `--help` with full parameter docs and examples:

```bash
phemex-cli place_order --help
```

Output:

```
Usage: phemex-cli place_order [options]

Place an order (Market, Limit, Stop, StopLimit)

Required Parameters:
  --symbol <string>          Trading pair (e.g. BTCUSDT)
  --side <string>            Buy or Sell
  --orderQty <number>        Quantity. linear: base amount (0.01 = 0.01 BTC). ...
  --ordType <string>         Order type: Market, Limit, Stop, StopLimit

Optional Parameters:
  --price <number>           Limit price (required for Limit/StopLimit)
  --timeInForce <string>     GoodTillCancel, PostOnly, ... [default: GoodTillCancel]
  --reduceOnly <boolean>     Only reduce position [default: false]
  ...

Examples:
  phemex-cli place_order --symbol BTCUSDT --side Buy --orderQty 0.01 --ordType Market
  phemex-cli place_order --symbol BTCUSDT --side Sell --orderQty 0.01 --ordType Limit --price 90000 --timeInForce PostOnly
```

More help examples:

```bash
phemex-cli get_ticker --help        # see params for price ticker
phemex-cli get_klines --help        # see resolution values for candlesticks
phemex-cli set_leverage --help      # see leverage param format
phemex-cli transfer_funds --help    # see direction values
phemex-cli list_symbols --help      # see contractType filter
```

### Friendly field names

By default, output uses readable field names:

```bash
phemex-cli get_ticker --symbol BTCUSDT
```

```json
{
  "closePrice": "70549.9",
  "openPrice": "70192.7",
  "highPrice": "70750",
  "lowPrice": "69160",
  "markPrice": "70549.9",
  "fundingRate": "-0.00003417",
  "volume": "5303.525",
  "turnover": "371204351.5978"
}
```

Use `--raw` to get original API field names (for scripts that depend on old format):

```bash
phemex-cli get_ticker --symbol BTCUSDT --raw
```

```json
{
  "closeRp": "70549.9",
  "openRp": "70192.7",
  "highRp": "70750",
  "lowRp": "69160",
  "markPriceRp": "70549.9",
  "fundingRateRr": "-0.00003417",
  "volumeRq": "5303.525",
  "turnoverRv": "371204351.5978"
}
```

**Field name mapping reference:**

| Suffix | Meaning | Example | Mapped to |
|--------|---------|---------|-----------|
| `Rp` | Real Price | `closeRp` | `closePrice` |
| `Rv` | Real Value | `accountBalanceRv` | `accountBalance` |
| `Rr` | Real Rate | `fundingRateRr` | `fundingRate` |
| `Rq` | Real Quantity | `volumeRq` | `volume` |

## Contract types

Every tool accepts an optional `--contractType` flag:

- `linear` (default) — USDT-M perpetual futures. Symbols end in USDT (e.g. BTCUSDT).
- `inverse` — Coin-M perpetual futures. Symbols end in USD (e.g. BTCUSD).
- `spot` — Spot trading. Symbols end in USDT (e.g. BTCUSDT). The server auto-prefixes `s` for the API.

## Tools

### Market data (no auth needed)

- `get_ticker` — 24hr price ticker. Example: `phemex-cli get_ticker --symbol BTCUSDT`
- `get_orderbook` — Order book (30 levels). Example: `phemex-cli get_orderbook --symbol BTCUSDT`
- `get_klines` — Candlestick data. Example: `phemex-cli get_klines --symbol BTCUSDT --resolution 3600 --limit 100`
- `get_recent_trades` — Recent trades. Example: `phemex-cli get_recent_trades --symbol BTCUSDT`
- `get_funding_rate` — Funding rate history. Example: `phemex-cli get_funding_rate --symbol .BTCFR8H --limit 20`

### Account (read-only, auth required)

- `get_account` — Balance and margin info. Example: `phemex-cli get_account --currency USDT`
- `get_spot_wallet` — Spot wallet balances. Example: `phemex-cli get_spot_wallet`
- `get_positions` — Current positions with PnL. Example: `phemex-cli get_positions --currency USDT`
- `get_open_orders` — Open orders. Example: `phemex-cli get_open_orders --symbol BTCUSDT`
- `get_order_history` — Closed/filled orders. Example: `phemex-cli get_order_history --symbol BTCUSDT --limit 50`
- `get_trades` — Trade execution history. Example: `phemex-cli get_trades --symbol BTCUSDT --limit 50`

### Trading (auth required)

- `place_order` — Place an order (Market, Limit, Stop, StopLimit). Key params: `--symbol`, `--side` (Buy/Sell), `--orderQty`, `--ordType`, `--price` (Limit/StopLimit), `--stopPx` (Stop/StopLimit), `--timeInForce` (GoodTillCancel/PostOnly/ImmediateOrCancel/FillOrKill), `--reduceOnly`, `--posSide` (Long/Short/Merged), `--stopLoss`, `--takeProfit`, `--qtyType` (spot only). **orderQty units differ by contract type:**
  - `linear` (USDT-M): orderQty = base currency amount (e.g. `0.01` = 0.01 BTC). To buy 10 USDT worth, calculate qty = 10 / current price.
  - `inverse` (Coin-M): orderQty = number of contracts as integer (e.g. `10` = 10 contracts). Each contract has a fixed USD value (e.g. 1 USD/contract for BTCUSD).
  - `spot`: depends on `--qtyType`. `ByBase` (default) = base currency (e.g. `0.01` = 0.01 BTC). `ByQuote` = quote currency (e.g. `50` = 50 USDT worth of BTC).
  - Example: `phemex-cli place_order --symbol BTCUSDT --side Buy --orderQty 0.01 --ordType Market`
- `amend_order` — Modify an open order. Example: `phemex-cli amend_order --symbol BTCUSDT --orderID xxx --price 95000`
- `cancel_order` — Cancel one order. Example: `phemex-cli cancel_order --symbol BTCUSDT --orderID xxx`
- `cancel_all_orders` — Cancel all orders for a symbol. Example: `phemex-cli cancel_all_orders --symbol BTCUSDT`
- `set_leverage` — Set leverage. Example: `phemex-cli set_leverage --symbol BTCUSDT --leverage 10`
- `switch_pos_mode` — Switch OneWay/Hedged. Example: `phemex-cli switch_pos_mode --symbol BTCUSDT --targetPosMode OneWay`

### Transfers (auth required)

- `transfer_funds` — Move funds between spot and futures. Example: `phemex-cli transfer_funds --currency USDT --amount 100 --direction spot_to_futures`
- `get_transfer_history` — Transfer history. Example: `phemex-cli get_transfer_history --currency USDT --limit 20`

### Utility

- `list_symbols` — List all available trading symbols, grouped by contract type.

```bash
# List all symbols (linear, inverse, spot)
phemex-cli list_symbols

# Only USDT-M perpetual futures
phemex-cli list_symbols --contractType linear

# Only Coin-M perpetual futures
phemex-cli list_symbols --contractType inverse

# Only spot pairs
phemex-cli list_symbols --contractType spot
```

Example output:

```json
{
  "linear": ["BTCUSDT", "ETHUSDT", "SOLUSDT", "BNBUSDT", ...],
  "inverse": ["BTCUSD", "ETHUSD", ...],
  "spot": ["BTCUSDT", "ETHUSDT", ...]
}
```

Use `list_symbols` to discover valid symbol names before trading. This avoids "invalid symbol" errors.

## Error messages

Errors return structured JSON with actionable guidance. Examples:

**Invalid symbol:**

```bash
phemex-cli get_ticker --symbol INVALIDXXX
```

```json
{
  "error": "Invalid symbol: INVALIDXXX",
  "code": 6001,
  "suggestion": "Symbol \"INVALIDXXX\" is not recognized. Check spelling and contract type.",
  "tip": "Run \"phemex-cli list_symbols\" to see all available symbols."
}
```

**Common typo (BTCUSD instead of BTCUSDT):**

```bash
phemex-cli get_ticker --symbol BTCUSD
```

```json
{
  "error": "Invalid symbol: BTCUSD",
  "code": 6001,
  "suggestion": "Did you mean BTCUSDT? For USDT perpetuals, use symbols ending in USDT (e.g. BTCUSDT).",
  "tip": "Run \"phemex-cli list_symbols\" to see all available symbols."
}
```

**Order quantity too large:**

```json
{
  "error": "Order quantity too large",
  "code": "TE_QTY_TOO_LARGE",
  "suggestion": "The order quantity exceeds the maximum allowed for BTCUSDT.",
  "tip": "Reduce --orderQty or check the symbol's max order size on Phemex."
}
```

**Other enhanced errors:** insufficient balance, invalid API key, rate limiting, invalid leverage, order not found — all include `suggestion` and `tip` fields.

## Safety rules

1. **Always confirm before placing orders.** Before calling `place_order`, show the user exactly what the order will do: symbol, side, quantity, type, price. Ask for confirmation.
2. **Always confirm before cancelling all orders.** Before calling `cancel_all_orders`, list the open orders first and confirm with the user.
3. **Explain leverage changes.** Before calling `set_leverage`, explain the implications (higher leverage = higher liquidation risk).
4. **Show context before trading.** Before suggesting a trade, show current positions and account balance so the user can make an informed decision.
5. **Never auto-trade.** Do not place orders without explicit user instruction.

## Common workflows

### Check a price

```bash
phemex-cli get_ticker --symbol BTCUSDT
```

### Discover available symbols

```bash
phemex-cli list_symbols --contractType linear
```

### Place a market buy (USDT-M futures)

```bash
phemex-cli place_order --symbol BTCUSDT --side Buy --orderQty 0.01 --ordType Market
```

### Place a limit sell (Coin-M futures)

```bash
phemex-cli place_order --symbol BTCUSD --side Sell --orderQty 10 --ordType Limit --price 100000 --contractType inverse
```

### Buy spot

```bash
phemex-cli place_order --symbol BTCUSDT --side Buy --orderQty 10 --ordType Market --contractType spot --qtyType ByQuote
```

### Check positions

```bash
phemex-cli get_positions --currency USDT
```

### Get help for any command

```bash
phemex-cli place_order --help
```

## Setup

### Option 1: Config file (recommended)

Create `~/.phemexrc` — credentials persist across sessions without exporting env vars:

```bash
# ~/.phemexrc
PHEMEX_API_KEY=your-api-key
PHEMEX_API_SECRET=your-api-secret
PHEMEX_API_URL=https://api.phemex.com

# Optional: max order value limit (USD)
PHEMEX_MAX_ORDER_VALUE=1000
```

That's it. All `phemex-cli` commands will pick up these values automatically.

### Option 2: Environment variables

```bash
export PHEMEX_API_KEY=your-api-key
export PHEMEX_API_SECRET=your-api-secret
export PHEMEX_API_URL=https://api.phemex.com
```

### Configuration priority

Settings are loaded in this order (highest priority first):

1. Command-line arguments
2. Environment variables
3. `~/.phemexrc` config file
4. Defaults (testnet URL)

This means env vars always override the config file, so you can safely keep production creds in `~/.phemexrc` and temporarily override with `PHEMEX_API_URL=https://testnet-api.phemex.com phemex-cli ...` for testing.

### Steps

1. Create a Phemex account at https://phemex.com
2. Create an API key (Account → API Management)
3. Save credentials to `~/.phemexrc` or export as environment variables
4. Verify: `phemex-cli list_symbols --contractType linear` should return symbols
5. Optionally set `PHEMEX_API_URL` (defaults to testnet `https://testnet-api.phemex.com` for safety; set to `https://api.phemex.com` for real trading)
6. Optionally set `PHEMEX_MAX_ORDER_VALUE` to limit maximum order size (USD)
