Max Open Interest and Order Cap Tiering System Explained

  • Updated

Overview

To protect market integrity, we have upgraded our tier-based system that limits the maximum open interest (OI) and maximum order size for certain perpetual symbols, specifically those categorized under Categories 4 to 13 in the Contracts Category.

This system manages risk by applying trading limits according to user credibility, measured through recent trading activity and account balance. Traders can gradually unlock higher trading caps when the tier criteria have been met.

 

How does the Tiering System work?


Your account is assigned a tier based on two key factors, evaluated over the past 30 days:

  1. Major Symbol Trading Volume
    This refers to your trading volume on major symbols, which are in Categories 1 to 3 (refer to Contracts Category for more details).
    Important: For the purpose of calculating trading volume under the Max Order/OI System, the total will include the sum of USDT-quoted volume and USD1-quoted volume (converted into USDT equivalent). 
  2. Average Account Balance
    Your average balance over the same 30-day period.

     

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

Tier 30D Major Symbol Volume (USDT) 30D Avg Balance (USDT) Max Order Size Cap for Categories 4-13 Max Open Interest Cap for Categories 4-13
Tier 1 0 – 250,000 USDT ≤ 5,000 USDT 20% 20%
Tier 2 250,000 – 500,000 USDT 5,000 – 8,000 USDT 30% 30%
Tier 3 500,000 – 1,000,000 USDT ≥ 8,000 USDT 40% 40%
Tier 4 1,000,000 – 3,000,000 USDT ≥ 8,000 USDT 50% 50%
Tier 5 3,000,000 – 10,000,000 USDT ≥ 8,000 USDT 70% 70%
Tier 6 10,000,000 – 1,000,000,000 USDT ≥ 8,000 USDT 100% 100%

 


Notes:

  1. Caps are expressed as a percentage of the maximum allowed for the symbol and category.
  2. Tiers will be evaluated and updated once daily at 00:00 UTC.
  3. For the purpose of this calculation, “30D Major Symbol Volume (USDT)” includes both USDT-quoted and USD1-quoted trading volume, with USD1-quoted amounts converted into their USDT equivalent.
  4. If any part of a trade’s fees, funding, or realized loss is covered by the Flipster Bonus, that trade will not count toward trading volume metrics.
  5. Trades paid fully or partially using USDT Bonus will either be excluded entirely or counted only in proportion to the user-funded (non-bonus) portion.
     

 

How does this affect you?

The Max OI & Order Cap Tiering System applies to all Category 4 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

  • 30-day major symbol volume: 50,000 USDT
  • 30-day average balance: 3,000 USDT

Result:

  • User qualifies for Tier 1.
  •  Trading limits: Max order size capped at 20%, max open interest capped at 20%.

 

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

  • 30-day major symbol volume: 300,000 USDT
  • 30-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 20%, max open interest capped at 20%.

 

Scenario 3: User meets both criteria for Tier 2

  • 30-day major symbol volume: 400,000 USDT
  • 30-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 30%, max open interest capped at 30%.

 

Scenario 4: High-activity user qualifying for Tier 5

  • 30-day major symbol volume: 5,000,000 USDT
  • 30-day average balance: 20,000 USDT

Result:

  • User qualifies for Tier 5.
  • Trading limits: Max order size capped at 70%, max open interest capped at 70%.

 

Scenario 5: User with both USDT-quoted and USD1-quoted volume

  • 30-day major symbol volume:
    • 600,000 USDT- quoted
    • 200,000 USD1- quoted (converted = 200,000 USDT)
    • Total = 800,000 USDT
  • 30-day average balance: 9,000 USDT

Result:

  • Combined total volume = 800,000 USDT.
  • Balance also meets the Tier 3 requirement.
  • User qualifies for Tier 3.
  • Trading limits: Max order size capped at 40%, max open interest capped at 40%.

 

 

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.
