@agentbadge/bstock-tracker

Delta tracker engine for Binance tokenized stocks (bStocks) vs underlying US equities (EPIC-141). Pure logic package — no server imports; consumed by hackathon/server wiring and the standalone Fly.io deployment.

Delta formula

delta% = (bStockMid − underlyingMid × multiplier) / (underlyingMid × multiplier) × 100

multiplier comes from Binance /sapi/v1/equity/market/tokenized-assets and is NOT always 1 (e.g. NVDAB = 1.00077822).

Config (env)

Required: BINANCE_BSTOK_API_KEY, BINANCE_BSTOK_API_SECRET, FINNHUB_API_KEY.

Optional: ALPACA_API_KEY + ALPACA_API_SECRET (fallback provider), TELEGRAM_BOT_BSTOK_TOKEN (+ TELEGRAM_BSTOK_CHAT_ID, TELEGRAM_BSTOK_BATCH_MS), MCP_AGENT_TOKENS (comma-separated bearers), threshold overrides BSTOCK_DELTA_ALERT_PCT (0.5), BSTOCK_STALE_MS (15000), BSTOCK_REST_POLL_MS (30000), BSTOCK_OFF_MARKET_ALERT_MS (10800000), BSTOCK_ROLLING_WINDOW_POINTS (1440).
