To ensure a fair and secure trading environment for all users, futures trading platforms implement specific risk management controls. A key mechanism among these is the concept of position limits. These rules are designed to prevent excessive market risk from being concentrated with a small number of traders and to help guard against potential market manipulation.
This guide explains how these limits work and what you need to know as a trader.
What Are Position Limits in Futures Trading?
Position limits are predefined thresholds that restrict the maximum size of a position a single user or group of connected accounts can hold in a particular futures contract. The limit is typically calculated as a percentage of the total open interest—the total value of all open positions—for that specific contract across the entire platform.
If a user's combined open orders and existing holdings for a single contract exceed this percentage threshold and a defined maximum size limit, the system will restrict new opening orders for that contract. It is important to note that orders placed to reduce or close an existing position (reduce-only orders) are usually not affected by this restriction.

Key Objectives of Implementing Position Limits
- Risk Management: Prevents the accumulation of dangerously large positions that could lead to significant losses for the individual and potentially trigger widespread market liquidations.
- Market Integrity: Deters manipulative practices, such as attempted cornering of the market or creating artificial price movements through excessively large orders.
- Fairness: Promotes a balanced and competitive market environment by ensuring no single participant has disproportionately large influence over a contract's price.
How the New Limits Are Being Phased In
The new position limit rules are being rolled out in batches for different futures contracts, including both perpetual swaps and delivery futures. The scheduled rollout is as follows:
Batch 1: Effective April 2, 2025
- Contracts Affected: NEO-USD-SWAP
Batch 2: Effective April 7 - April 9, 2025
Contracts Affected:
- 1INCH-USD-SWAP
- THETA-USD-SWAP
- WAXP-USDT-SWAP
- KISHU-USDT-SWAP
Remaining Batches: Effective April 9 - April 21, 2025
- Contracts Affected: All remaining futures contracts.
- Note: The exact timing for the remaining contracts may be adjusted based on evolving market conditions to ensure a smooth implementation.
Frequently Asked Questions
What happens if I reach the position limit?
If your account's total open orders and existing positions for a specific contract exceed the established limit, the platform will block any new orders that would open additional long or short positions. You will still be able to place orders to reduce or close your current holdings.
Do these limits apply to both main and sub-accounts?
Yes. The position limit calculation aggregates the holdings and orders across a user's main account and all associated sub-accounts. The limit is applied to the entire account group, not individually.
Why are reduce-only orders not affected?
Reduce-only orders are designed solely to decrease exposure and manage risk by closing out existing positions. Allowing them to continue even when a limit is hit is crucial for risk management, as it enables traders to exit their positions without restriction.
How can I check the current open interest for a contract?
Most trading platforms provide real-time data on open interest for each contract within their market data or advanced trading sections. Monitoring this can help you understand the overall market size.
Where can I find the specific threshold percentages for each contract?
The detailed methodology, including the exact percentage thresholds and maximum size limits for each contract, is officially published by the trading platform. Traders should refer to the latest help documents and announcements for precise figures.
Can these rules change?
Yes. Trading platforms reserve the right to adjust position limit parameters, including thresholds and the list of affected contracts, in response to significant changes in market volatility, liquidity, or other risk factors. Always stay informed through official channels.
