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

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.
