To better serve professional traders, OrangeX has updated the notional position limits and corresponding maintenance margin rates for 200X, 100X, 75X, and 50X perpetual contracts, effective March 1, 2025, at 13:00 UTC.
The maximum leverage is contingent on the notional value of your position. This means that the amount of leverage decreases as your position size increases. You have the flexibility to adjust the leverage to meet your specific requirements and all position sizes are calculated based on the notional value of the contract. Therefore, the leverage you choose directly affects the Initial Margin.
Dynamic Leverage Adjustment
Your maximum available leverage is determined by your position's notional value. As your position size increases, your leverage decreases. You may freely adjust your leverage to suit your trading strategy, with all position sizes calculated based on contract notional value. Note that your selected leverage directly impacts the Initial Margin requirement.
Pre-Trade Requirements
Before opening any position, you must:
Select your desired leverage level
Meet the Initial Margin requirement
Important: Higher leverage permits smaller notional positions, while lower leverage allows larger notional positions.
Perpetual Contract Maintenance Margin Description
Maintenance Margin Rate
The Maintenance Margin Rate corresponds to your position's notional value in USDT, as shown in the table below. Example: For a USDT-margined BTCUSDT contract with a 264,000 USDT position, the Maintenance Margin Rate is 0.5%.
Please note that the Maintenance Margin is calculated based on your positions at different notional value tiers. If your position (calculated at the liquidation price) and the current position (calculated at the current mark price) are of different levels, then you must substitute (i.e. to calculate at the liquidation price) the maintenance margin rate and the maintenance margin amount of the position level, to recompute the liquidation price.
Maintenance Amount
Refer to the table below for Maintenance Amounts by position value. Example: A 100,000 USDT position in a USDT-margined BTCUSDT contract has a 100 USDT Maintenance Amount.
Maintenance Amount Formula
nitial Margin = Notional Position Value / Leverage Level
Maintenance Margin = Notional Position Value x Maintenance Margin Rate - Maintenance Amount
Maintenance Amount on Level n= ( Floor of Position Bracket on Level n × difference between Maintenance
Margin Rate on Level n and Maintenance Margin Rate on Level n-1) + Maintenance Amount on Level n-1
