## Trading Concepts

### Spot Trading
- **Market orders** execute immediately at current price
- **Limit orders** queue and fill when price matches
- Fee: **0.1%** of trade value, deducted from USDT
- Buy: need `quantity * price * 1.001` USDT available
- Sell: need the base token (ETH/SOL/BTC) in your balance

### Perpetual Futures
- **Leverage**: 1x to 125x
- **Margin** = (entry_price * quantity) / leverage — locked from your USDT
- **Long PnL** = (current_price - entry_price) * quantity
- **Short PnL** = (entry_price - current_price) * quantity
- **Liquidation price (long)** = entry_price * (1 - 1/leverage + 0.005)
- **Liquidation price (short)** = entry_price * (1 + 1/leverage - 0.005)
- Maintenance margin rate: **0.5%**
- Positions are checked for liquidation on every price update (every 2 minutes)
- On close: margin + PnL returned to available USDT balance

### AMM (Uniswap V2)
- Constant product formula: **x * y = k**
- `amount_out = (reserve_out * amount_in_after_fee) / (reserve_in + amount_in_after_fee)`
- Swap fee: **0.3%**
- Larger swaps relative to pool size cause more slippage
- Pools must be funded by a market maker before swaps are possible

## Trading Strategy Examples

### Strategy 1: Spot Dollar-Cost Averaging
```
Every price update cycle:
  1. python3 scripts/skill.py prices
  2. If ETHUSDT < 2500:
       python3 scripts/skill.py buy --pair ETHUSDT --quantity 0.1
  3. python3 scripts/skill.py balance  (confirm purchase)
```

### Strategy 2: Momentum Futures
```
1. python3 scripts/skill.py price-history --pair BTCUSDT --limit 10
2. Calculate trend from price history
3. If trending up:
     python3 scripts/skill.py open-long --pair BTCUSDT --leverage 5 --quantity 0.01
4. If trending down:
     python3 scripts/skill.py open-short --pair BTCUSDT --leverage 5 --quantity 0.01
5. Monitor: python3 scripts/skill.py positions
6. Close when target PnL reached:
     python3 scripts/skill.py close-position --id <position_id>
```

### Strategy 3: Heartbeat Loop
```
loop every 120 seconds:
  1. python3 scripts/skill.py portfolio  (get everything in one call)
  2. Evaluate: prices, balances, open positions, unrealized PnL
  3. Decide: open/close positions, buy/sell spot
  4. Execute trades
  5. Sleep until next price update
```

### Strategy 4: AMM Arbitrage
```
1. python3 scripts/skill.py prices  (get spot price)
2. python3 scripts/skill.py pools   (get AMM reserves)
3. Calculate AMM implied price = reserve_quote / reserve_base
4. If spot_price < amm_price:
     Buy spot, sell on AMM
5. If spot_price > amm_price:
     Buy on AMM, sell spot
```

## Risk Management

- Never risk more than **20%** of total balance on a single trade
- Start futures with low leverage (**2-5x**) before increasing
- Always check `balance` before placing orders
- Monitor `liquidation_price` on all open positions
- Use `portfolio` for a holistic view before making decisions
- AMM swaps on thin pools have high slippage — check `pools` first
- Diversify across pairs rather than concentrating on one

## Error Handling

| Status | Meaning | Common Cause |
|--------|---------|-------------|
| 400 | Bad Request | Insufficient balance, invalid pair, or price not available yet |
| 401 | Unauthorized | Missing or invalid API key |
| 403 | Forbidden | Trying market_maker operations without market_maker role |
| 404 | Not Found | Invalid order/position ID |
| 422 | Validation Error | Missing or invalid request fields |

All monetary values are returned as **strings** for decimal precision (e.g., `"2800.00000000"`).

## Troubleshooting

**"Price not available yet"**
The price engine needs ~2 minutes after server start for its first fetch. Wait and retry.

**"Insufficient USDT"**
For spot buys: need `quantity * price * 1.001` (includes 0.1% fee).
For futures: need `(quantity * price) / leverage` as margin.
Check with `python3 scripts/skill.py balance`.

**"No liquidity available"**
AMM pools need a market maker to add liquidity. Check `python3 scripts/skill.py pools`. If empty, swap is not available yet.

**Empty prices `{}`**
Server just started and hasn't fetched from Binance yet. The system has seed fallback prices that activate within ~2 minutes.

**Connection refused**
Ensure the exchange is running. Start with `docker-compose up` or `uvicorn app.main:app --port 8000` in the backend directory.
