Q: Does my fee tier reset every month?

A: No, your fee tier is not based on a monthly reset — it's calculated on a rolling 30-day basis. Here's how it works:

• All data is based on the server's time zone (UTC).
• Your 30-day spot trading volume is calculated hourly. At 1:00 AM UTC the next day, your daily spot trading volume over the past 30 days is calculated first, converted into USD based on that day's exchange rate, and then all 30 days of USD-converted volume are added together.
• Your VIP/fee tier level is then updated daily starting at 2:00 AM UTC, based on this rolling 30-day volume.

This means your tier can move up or down daily depending on your trading activity over the trailing 30-day window, rather than resetting at a fixed monthly date.
