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

StatusMeaningCommon Cause
400Bad RequestInsufficient balance, invalid pair, or price not available yet
401UnauthorizedMissing or invalid API key
403ForbiddenTrying market_maker operations without market_maker role
404Not FoundInvalid order/position ID
422Validation ErrorMissing 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.
