Max Open Interest and Order Cap Tiering System Explained

Overview

To protect market integrity and reduce the risk of price manipulation, we have introduced a new tier-based system that limits the maximum open interest (OI) and maximum order size for certain perpetual symbols, specifically those categorized under Categories 9 to 13 in the Contracts Category.

This system is designed to manage risk by applying trading limits according to user credibility, measured through recent trading activity and account balance. It will eventually allow traders to gradually unlock higher trading cap when the tier criteria has been met.

How does the Tiering System work?

Your account is assigned a tier based on two key factors, evaluated over the past 15 days:

1. Major Symbol Trading Volume:
   This refers to your trading volume on major symbols, which are in Categories 1 to 8 (refer to Contracts Category for more details).
2. Average Account Balance:
   Your average balance over the same 15-day period.

Both criteria must be met to qualify for a higher tier. Refer to the table below for more details.

Note:

1. Caps are expressed as a percentage of the maximum allowed for the symbol and category.
2. Tier will be evaluated and updated once daily at 00:00 UTC.
3. VIP users are automatically enrolled to Tier 3.

What are major symbols?

Major symbols are those within categories 1 to 8. Your trading volume on these symbols is a key factor for tier qualification. You may check which symbols fall under these categories via this link.

How does this affect you?

• The Max OI & Order Cap Tiering System applies to all Category 9 to 13 trading pairs.
• For newly listed symbols, 100% caps are enforced for the first 72 hours post-listing to minimize risk, after which tier-based caps are applied.

Examples

Scenario 1: New user with low trading volume and wallet balance

• 15-day major symbol volume: 50,000 USDT
• 15-day average balance: 3,000 USDT
• Result:
  User qualifies for Tier 1 since both volume and balance are below Tier 2 thresholds.
  Trading limits: Max order size capped at 25%, max open interest capped at 50%.

Scenario 2: User meets trading volume but not the wallet balance

• 15-day major symbol volume: 120,000 USDT
• 15-day average balance: 4,000 USDT
• Result:
  Volume meets Tier 2, but balance does not.
  User remains in Tier 1 (the lower tier).
  Trading limits: Max order size capped at 25%, max open interest capped at 50%.

Scenario 3: User meets both criteria for Tier 2

• 15-day major symbol volume: 150,000 USDT
• 15-day average balance: 6,000 USDT
• Result:
  Both volume and balance meet Tier 2 requirements.
  User qualifies for Tier 2.
  Trading limits: Max order size capped at 35%, max open interest capped at 70%.

Scenario 4: High-activity user qualifying for Tier 3

• 15-day major symbol volume: 300,000 USDT
• 15-day average balance: 10,000 USDT
• Result:
  User qualifies for Tier 3 (highest tier).
  Trading limits: Full 100% max order size and open interest caps.

What This Means for You

• If you are an active trader with a consistent balance, you can expect to progress through the tiers automatically, gaining higher trading limits.
• New or low-activity accounts will start with tighter limits to protect the market.
