BOC Forex Monitor

Set up a configurable Bank of China foreign-exchange monitor with per-currency thresholds and price columns.

What this skill provides

• Fetch BOC forex data from https://www.boc.cn/sourcedb/whpj/
• Track any configured currency using any price column (现汇买入价/现钞买入价/现汇卖出价/现钞卖出价/中行折算价)
• Compare current values against a rolling baseline
• Skip monitoring during quiet hours (default 23:00-09:00 Asia/Shanghai)
• Trigger on per-currency configurable thresholds:
  • Rise, drop, or both directions
  • Configurable threshold values (default 0.5)
• Deduplicate notifications using local state files
• Support optional OpenClaw message delivery (for example Feishu)

Files in this skill

• scripts/boc_forex_check.py: fetch + parse + compare + trigger generation
• scripts/boc_forex_cron_runner.py: stable cron entrypoint; runs the checker, formats output, deduplicates, and optionally sends a notification
• references/configuration.md: configuration knobs and install patterns

Setup workflow

1. Read references/configuration.md.
2. Create .openclaw-state/boc-forex-monitor-config.json in your workspace with your desired monitoring targets.
3. Copy both scripts into <workspace>/scripts/.
4. Make both scripts executable.
5. Create or update a cron job with the OpenClaw cron tool.
6. Prefer a short agentTurn payload that only executes the runner script and returns stdout verbatim.
7. Verify with a manual script run before claiming success.

Cron payload pattern

Use an isolated agentTurn job. Keep the prompt minimal.

Recommended payload message:

Workdir is <workspace>. Execute:
python3 scripts/boc_forex_cron_runner.py [--notify-channel <channel>] [--notify-target <target>] [--notify-account-id <id>]

Requirements:
1) Reply with stdout only.
2) Do not add explanation.
3) If stdout is empty, reply: ❌ 汇率检查执行失败

Recommended schedule

Use this cron schedule for every 5 minutes during local daytime trading-watch hours:

{ "kind": "cron", "expr": "*/5 9-22 * * *", "tz": "Asia/Shanghai" }

Validation

Before finishing:

1. Run python3 scripts/boc_forex_cron_runner.py from the target workspace.
2. Confirm it returns one of:
   • ✅ 汇率检查完成
   • ⏭️ 汇率检查跳过
   • 🔔 已触发阈值并发送...
3. If notifications are enabled, verify dedupe state is written to .openclaw-state/boc-forex-alert-notify-state.json.

Safety

• Never publish private recipient ids inside the skill bundle.
• Keep notification destinations as runtime parameters or environment variables.
• Do not send routine success messages to chat channels unless the user explicitly wants them.
