| description | Execute BNB Chain EVM swing trades after importing a private key: buy when trigger price exceeds market condition, then place 5% take-profit and 3% stop-loss management. Use when user asks to automate BNB band/swing trading with strict TP/SL and wallet-key based execution. |
EVM BNB Band Trader
Implement BNB Chain swing trading with strict risk controls.
1) Configure secrets and params
Set environment variables before running:
EVM_PRIVATE_KEY (wallet private key, never hardcode)BNB_RPC_URL (BSC RPC endpoint)TOKEN_IN (default WBNB)TOKEN_OUT (target token)BUY_TRIGGER_PRICE (trigger buy threshold)BUY_SIZE_BNB (position size in BNB)TAKE_PROFIT_PCT (default 0.05)STOP_LOSS_PCT (default 0.03)POLL_SECONDS (default 10)
2) Run bot
Use script:
python scripts/bnb_band_bot.py --mode run
Dry run first:
python scripts/bnb_band_bot.py --mode dry-run
3) Strategy rules (fixed)
- Entry: execute buy when latest price >=
BUY_TRIGGER_PRICE
- Exit TP: sell when price >= entry_price * 1.05
- Exit SL: sell when price <= entry_price * 0.97
- One-position mode: no pyramiding
4) Safety controls
- Refuse run if env vars missing
- Refuse run if private key format invalid
- Refuse run if gas or balance insufficient
- Log every decision with timestamp
5) Notes
- Script uses DEX quote+swap placeholder flow; wire production router/aggregator before real funds.
- Always run dry-run first and validate slippage/gas assumptions.
