Target-price alerts
With Pro, choose a target in your preferred currency. An email is sent when the monthly reference price crosses from above the target to at or below it. Quote or exchange-rate changes can trigger this. Supported currencies: CNY, USD, EUR, GBP, JPY, HKD.
Budget assistant allowance
When the budget assistant is available, free accounts can send 15 messages per day and Pro accounts 100. Allowances reset at midnight Beijing time. The assistant may be paused or unavailable during maintenance.

Read the Pro service termsFrequently asked questions
Do I need Pro to use price alerts?
No. Verified accounts can set up 3 quote-change alerts for free. Pro raises the active-alert limit to 20, adds target-price alerts and increases the budget assistant message allowance.
How do the two alert types differ?
Quote-change alerts track changes to the original local quote and its billing details; exchange-rate movements alone do not trigger them. Target-price alerts compare the monthly reference price in your chosen currency, so exchange-rate changes can also trigger a notification. Saving an alert does not send notifications for earlier changes.
Will I receive an email immediately when a price changes?
Alerts depend on successful collection and email delivery; they are not real-time monitoring. Missing sources, delayed collection or email outages can delay notifications. Recent delivery records are available in your account.
What happens if I cancel Pro renewal?
Pro access continues through the paid period. After it ends, quote-change alerts are subject to the free allowance; target-price alerts and alerts above that allowance no longer send notifications.
