--- name: cron_timing description: Crontab timing strategy — 30s offset from candle close, avoid collisions between scripts type: project --- ## Crontab 排程 - `main.py`:`*/5 * * * * sleep 30 && ...`(:00:30, :05:30, :10:30...) - `sync_cost_basis.py`:`2,32 * * * *`(:02, :32) **Why:** Bitfinex 5 分鐘 K 線在整點收盤(:00, :05, :10...),延遲 30 秒確保數據到位。sync_cost_basis 在 :02/:32 避免衝突。 **How to apply:** crontab 不支援秒,用 `sleep 30 &&` 實現。修改排程時維持此偏移策略。
