#### 🌟 Beginner Mode Configuration (Recommended)

**Step 1**: Copy and rename the example config file

```bash
cp config.json.example config.json
```

**Step 2**: Edit `config.json` with your API keys

```json
{
  "traders": [
    {
      "id": "my_trader",
      "name": "My AI Trader",
      "ai_model": "deepseek",
      "binance_api_key": "YOUR_BINANCE_API_KEY",
      "binance_secret_key": "YOUR_BINANCE_SECRET_KEY",
      "use_qwen": false,
      "deepseek_key": "sk-xxxxxxxxxxxxx",
      "qwen_key": "",
      "initial_balance": 1000.0,
      "scan_interval_minutes": 3
    }
  ],
  "leverage": {
    "btc_eth_leverage": 5,
    "altcoin_leverage": 5
  },
  "use_default_coins": true,
  "coin_pool_api_url": "",
  "oi_top_api_url": "",
  "api_server_port": 8080

- Example: If you have 500 USDT, set `"initial_balance": 500.0`

**✅ Configuration Checklist:**

- [ ] Binance API key filled in (no quotes issues)
- [ ] Binance Secret key filled in (no quotes issues)
- [ ] DeepSeek API key filled in (starts with `sk-`)
- [ ] `use_default_coins` set to `true` (for beginners)
- [ ] `initial_balance` matches your account balance
- [ ] File saved as `config.json` (not `.example`)

---

#### 🔷 Alternative: Using Hyperliquid Exchange

**NOFX also supports Hyperliquid** - a decentralized perpetual futures exchange. To use Hyperliquid instead of Binance:

**Step 1**: Get your Ethereum private key (for Hyperliquid authentication)

1. Open **MetaMask** (or any Ethereum wallet)
2. Export your private key
3. **Remove the `0x` prefix** from the key
4. Fund your wallet on [Hyperliquid](https://hyperliquid.xyz)

**Step 2**: Configure `config.json` for Hyperliquid

```json
{
  "traders": [
    {
      "id": "hyperliquid_trader",
      "name": "My Hyperliquid Trader",
      "enabled": true,
      "ai_model": "deepseek",
      "exchange": "hyperliquid",
      "hyperliquid_private_key": "your_private_key_without_0x",
      "hyperliquid_wallet_addr": "your_ethereum_address",
      "hyperliquid_testnet": false,
      "deepseek_key": "sk-xxxxxxxxxxxxx",
      "initial_balance": 1000.0,
      "scan_interval_minutes": 3
    }
  ],
  "use_default_coins": true,
  "api_server_port": 8080
}
```

**Key Differences from Binance Config:**
- Replace `binance_api_key` + `binance_secret_key` with `hyperliquid_private_key`
- Add `"exchange": "hyperliquid"` field
- Set `hyperliquid_testnet: false` for mainnet (or `true` for testnet)

**⚠️ Security Warning**: Never share your private key! Use a dedicated wallet for trading, not your main wallet.

---

#### ⚙️ Leverage Configuration (v2.0.3+)

**What is leverage configuration?**

The leverage settings control the maximum leverage the AI can use for each trade. This is crucial for risk management, especially for Binance subaccounts which have leverage restrictions.

**Configuration format:**

```json
"leverage": {
  "btc_eth_leverage": 5,    // Maximum leverage for BTC and ETH
  "altcoin_leverage": 5      // Maximum leverage for all other coins
}
```

**⚠️ Important: Binance Subaccount Restrictions**

- **Subaccounts**: Limited to **≤5x leverage** by Binance
- **Main accounts**: Can use up to 20x (altcoins) or 50x (BTC/ETH)
- If you're using a subaccount and set leverage >5x, trades will **fail** with error: `Subaccounts are restricted from using leverage greater than 5x`

**Recommended settings:**

| Account Type | BTC/ETH Leverage | Altcoin Leverage | Risk Level |
|-------------|------------------|------------------|------------|
| **Subaccount** | `5` | `5` | ✅ Safe (default) |
| **Main (Conservative)** | `10` | `10` | 🟡 Medium |
| **Main (Aggressive)** | `20` | `15` | 🔴 High |
| **Main (Maximum)** | `50` | `20` | 🔴🔴 Very High |

**Examples:**

**Safe configuration (subaccount or conservative):**
```json
"leverage": {
  "btc_eth_leverage": 5,
  "altcoin_leverage": 5
}
```

**Aggressive configuration (main account only):**
```json
"leverage": {
  "btc_eth_leverage": 20,
  "altcoin_leverage": 15
}
```

**How AI uses leverage:**

- AI can choose **any leverage from 1x up to your configured maximum**
- For example, with `altcoin_leverage: 20`, AI might decide to use 5x, 10x, or 20x based on market conditions
- The configuration sets the **upper limit**, not a fixed value
- AI considers volatility, risk-reward ratio, and account balance when choosing leverage

---

#### ⚠️ Important: `use_default_coins` Field

**Smart Default Behavior (v2.0.2+):**

The system now automatically defaults to `use_default_coins: true` if:
- You don't include this field in config.json, OR
- You set it to `false` but don't provide `coin_pool_api_url`

This makes it beginner-friendly! You can even omit this field entirely.

**Configuration Examples:**

✅ **Option 1: Explicitly set (Recommended for clarity)**
```json
"use_default_coins": true,
"coin_pool_api_url": "",
"oi_top_api_url": ""
```

✅ **Option 2: Omit the field (uses default coins automatically)**
```json
// Just don't include "use_default_coins" at all
"coin_pool_api_url": "",
"oi_top_api_url": ""
```

⚙️ **Advanced: Use external API**
```json
"use_default_coins": false,
"coin_pool_api_url": "http://your-api.com/coins",
"oi_top_api_url": "http://your-api.com/oi"
```

### 6. Run the System

#### 🚀 Starting the System (2 steps)

The system has **2 parts** that run separately:
1. **Backend** (AI trading brain + API)
2. **Frontend** (Web dashboard for monitoring)

---

#### **Step 1: Start the Backend**

Open a terminal and run:

```bash
# Build the program (first time only, or after code changes)
go build -o nofx

# Start the backend
./nofx
```

**What you should see:**

```
🚀 启动自动交易系统...
✓ Trader [my_trader] 已初始化
✓ API服务器启动在端口 8080
📊 开始交易监控...
```

**⚠️ If you see errors:**

| Error Message | Solution |
|--------------|----------|
| `invalid API key` | Check your Binance API key in config.json |
| `TA-Lib not found` | Run `brew install ta-lib` (macOS) |
| `port 8080 already in use` | Change `api_server_port` in config.json |
| `DeepSeek API error` | Verify your DeepSeek API key and balance |

**✅ Backend is running correctly when you see:**
- No error messages
- "开始交易监控..." appears
- System shows account balance
- Keep this terminal window open!

---

#### **Step 2: Start the Frontend**

Open a **NEW terminal window** (keep the first one running!), then:

```bash
cd web
npm run dev
```

**What you should see:**

```
VITE v5.x.x  ready in xxx ms

➜  Local:   http://localhost:3000/
➜  Network: use --host to expose
```

**✅ Frontend is running when you see:**
- "Local: http://localhost:3000/" message
- No error messages
- Keep this terminal window open too!

---

#### **Step 3: Access the Dashboard**

Open your web browser and visit:

**🌐 http://localhost:3000**

**What you'll see:**
- 📊 Real-time account balance
- 📈 Open positions (if any)
- 🤖 AI decision logs
- 📉 Equity curve chart

**First-time tips:**
- It may take 3-5 minutes for the first AI decision
- Initial decisions might say "观望" (wait) - this is normal
- AI needs to analyze market conditions first

---

### 7. Monitor the System

**What to watch:**

✅ **Healthy System Signs:**
- Backend terminal shows decision cycles every 3-5 minutes
- No continuous error messages
- Account balance updates
- Web dashboard refreshes automatically

⚠️ **Warning Signs:**
- Repeated API errors
- No decisions for 10+ minutes
- Balance decreasing rapidly

**Checking System Status:**

```bash
# In a new terminal window
curl http://localhost:8080/health
```

Should return: `{"status":"ok"}`

---

### 8. Stop the System

**Graceful Shutdown (Recommended):**

1. Go to the **backend terminal** (the first one)
2. Press `Ctrl+C`
3. Wait for "系统已停止" message
4. Go to the **frontend terminal** (the second one)
5. Press `Ctrl+C`

**⚠️ Important:**
- Always stop the backend first
- Wait for confirmation before closing terminals
- Don't force quit (don't close terminal directly)

### Key Improvements in v2.0.2

**📌 Position Duration Tracking:**
- System now tracks how long each position has been held
- Displayed in user prompt: "持仓时长2小时15分钟"
- Helps AI make better decisions on when to exit

**📌 Accurate PnL Calculation:**
- Previously: Only percentage (100U@5% = 1000U@5% = both showed "5.0")
- Now: Real USDT profit = Position Value × Price Change × Leverage
- Example: 1000 USDT × 5% × 20x = 1000 USDT actual profit

**📌 Enhanced AI Freedom:**
- AI can freely analyze all raw sequence data
- No longer restricted to predefined indicator combinations
- Can perform own trend analysis, support/resistance calculation

**📌 Improved Position Tracking:**
- Uses `symbol_side` key (e.g., "BTCUSDT_long")
- Prevents conflicts when holding both long & short
- Stores complete data: quantity, leverage, open/close times

## 🧠 AI Self-Learning Example

### Historical Feedback (Auto-added to Prompt)

```markdown
## 📊 Historical Performance Feedback

### Overall Performance
- **Total Trades**: 15 (Profit: 8 | Loss: 7)
- **Win Rate**: 53.3%
- **Average Profit**: +3.2% | Average Loss: -2.1%
- **Profit/Loss Ratio**: 1.52:1

### Recent Trades
1. BTCUSDT LONG: 95000.0000 → 97500.0000 = +2.63% ✓
2. ETHUSDT SHORT: 3500.0000 → 3450.0000 = +1.43% ✓
3. SOLUSDT LONG: 185.0000 → 180.0000 = -2.70% ✗
4. BNBUSDT LONG: 610.0000 → 625.0000 = +2.46% ✓
5. ADAUSDT LONG: 0.8500 → 0.8300 = -2.35% ✗

### Coin Performance
- **Best**: BTCUSDT (Win rate 75%, avg +2.5%)
- **Worst**: SOLUSDT (Win rate 25%, avg -1.8%)
```

### How AI Uses Feedback

1. **Avoid consecutive losers**: Seeing SOLUSDT with 3 consecutive stop-losses, AI avoids or is more cautious
2. **Reinforce successful strategies**: BTC breakout long with 75% win rate, AI continues this pattern
3. **Dynamic style adjustment**: Win rate <40% → conservative; P/L ratio >2 → maintain aggressive
4. **Identify market conditions**: Consecutive losses may indicate choppy market, reduce trading frequency

## ⚠️ Important Risk Warnings

### Trading Risks

1. **Cryptocurrency markets are extremely volatile**, AI decisions don't guarantee profit
2. **Futures trading uses leverage**, losses may exceed principal
3. **Extreme market conditions** may lead to liquidation risk
4. **Funding rates** may affect holding costs
5. **Liquidity risk**: Some coins may experience slippage

### Technical Risks

1. **Network latency** may cause price slippage
2. **API rate limits** may affect trade execution
3. **AI API timeouts** may cause decision failures
4. **System bugs** may trigger unexpected behavior

### Usage Recommendations

✅ **Recommended**
- Use only funds you can afford to lose for testing
- Start with small amounts (recommended 100-500 USDT)
- Regularly check system operation status
- Monitor account balance changes
- Analyze AI decision logs to understand strategy

❌ **Not Recommended**
- Invest all funds or borrowed money
- Run unsupervised for long periods
- Blindly trust AI decisions
- Use without understanding the system
- Run during extreme market volatility

---

## 🛠️ Common Issues

### 1. Compilation error: TA-Lib not found

**Solution**: Install TA-Lib library
```bash
# macOS
brew install ta-lib

# Ubuntu
sudo apt-get install libta-lib0-dev
```

### 2. Precision error: Precision is over the maximum

**Solution**: System auto-handles precision from Binance LOT_SIZE. If error persists, check network connection.

### 3. AI API timeout

**Solution**:
- Check if API key is correct
- Check network connection (may need proxy)
- System timeout is set to 120 seconds

### 4. Frontend can't connect to backend

**Solution**:
- Ensure backend is running (http://localhost:8080)
- Check if port 8080 is occupied
- Check browser console for errors

### 5. Coin pool API failure

**Solution**:
- Coin pool API is optional
- If API fails, system uses default mainstream coins (BTC, ETH, etc.)
- Check API URL and auth parameter in config.json

---

## 📈 Performance Optimization Tips

1. **Set reasonable decision cycle**: Recommended 3-5 minutes, avoid over-trading
2. **Control candidate coin count**: System defaults to AI500 top 20 + OI Top top 20
3. **Regularly clean logs**: Avoid excessive disk usage
4. **Monitor API call count**: Avoid triggering Binance rate limits
5. **Test with small capital**: First test with 100-500 USDT for strategy validation

## 🔄 Changelog

### v2.0.2 (2025-10-29)

**Critical Bug Fixes - Trade History & Performance Analysis:**

This version fixes **critical calculation errors** in the historical trade record and performance analysis system that significantly affected profitability statistics.

**1. PnL Calculation - Major Error Fixed** (logger/decision_logger.go)
- **Problem**: Previously calculated PnL as percentage only, completely ignoring position size and leverage
  - Example: 100 USDT position earning 5% and 1000 USDT position earning 5% both showed `5.0` as profit
  - This made performance analysis completely inaccurate
- **Solution**: Now calculates actual USDT profit amount
  ```
  PnL (USDT) = Position Value × Price Change % × Leverage
  Example: 1000 USDT × 5% × 20x = 1000 USDT actual profit
  ```
- **Impact**: Win rate, profit factor, and Sharpe ratio now based on accurate USDT amounts

**2. Position Tracking - Missing Critical Data**
- **Problem**: Open position records only stored price and time, missing quantity and leverage
- **Solution**: Now stores complete trade data:
  - `quantity`: Position size (in coins)
  - `leverage`: Leverage multiplier (e.g., 20x)
  - These are essential for accurate PnL calculations

**3. Position Key Logic - Long/Short Conflict**
- **Problem**: Used `symbol` as position key, causing data conflicts when holding both long and short
  - Example: BTCUSDT long and BTCUSDT short would overwrite each other
- **Solution**: Changed to `symbol_side` format (e.g., `BTCUSDT_long`, `BTCUSDT_short`)
  - Now properly distinguishes between long and short positions

**4. Sharpe Ratio Calculation - Code Optimization**
- **Problem**: Used custom Newton's method for square root calculation
- **Solution**: Replaced with standard library `math.Sqrt`
  - More reliable, maintainable, and efficient

**Why This Update Matters:**
- ✅ Historical trade statistics now show **real USDT profit/loss** instead of meaningless percentages
- ✅ Performance comparison between different leverage trades is now accurate
- ✅ AI self-learning mechanism receives correct historical feedback
- ✅ Profit factor and Sharpe ratio calculations are now meaningful
- ✅ Multi-position tracking (long + short simultaneously) works correctly

**Recommendation**: If you were running the system before this update, your historical statistics were inaccurate. After updating to v2.0.2, new trades will be calculated correctly.

### v2.0.2 (2025-10-29)
