description: Crontab timing strategy — 30s offset from candle close, avoid collisions between scripts

## 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。
