AI News BNB Trader

TypeScript (Node.js 20+) AI news-driven BNB strategy trading bot for BSC. Use when user wants event/news sentiment signals, strict risk controls, and automated WBNB<->stablecoin swaps with dry-run safety, panic mode, status, and approval revoke tooling.

Run an event-driven BSC trading bot using news sentiment + risk gates.

Safety first

• Default DRY_RUN=true.
• Never print private key/seed in logs.
• Only whitelist assets (WBNB, USDT/BUSD/USDC).
• Panic mode immediately disables trading.

Commands

bash

npm run start -- start
npm run start -- status
npm run start -- panic
npm run start -- revoke-approvals
npm run key:encrypt -- --out ./secrets/key.json

News modes

• Poll REST via NEWS_API_URL every NEWS_POLL_SECONDS
• Optional WebSocket via NEWS_WS_URL

Both modes dedupe on news.id and log failures with exponential backoff.

Signal models

• RuleSignalModel (default): keyword rules with explainable reasons
• OpenAISignalModel (optional): enabled when OPENAI_API_KEY is set; timeout + fallback to rules

Strategy

• Buy WBNB with stablecoin if sentiment * impact >= BUY_THRESHOLD and confidence >= MIN_CONF
• Sell WBNB to stablecoin if sentiment * impact <= -SELL_THRESHOLD and confidence >= MIN_CONF
• Enforce all risk gates before execution

Risk controls

• Max order notional / max position pct / daily trade cap
• Daily loss cap (MTM approximation)
• TP/SL from avg entry
• Cooldown between trades
• Slippage cap from quote
• Consecutive failures -> SAFE_MODE

Notes

• Prefer private RPC (PRIVATE_RPC_URL) when provided.
• For production: validate token/DEX addresses and add deeper MEV defenses.
