The cryptocurrency derivatives market is continuously evolving, and with it, the tools and risk management systems that support traders. OKX has taken a significant step forward by rolling out graded margin mode across all coin-margined delivery contracts. This enhancement allows users with open positions (and no pending orders) to seamlessly switch from the legacy “single liquidation” mode to the new graded margin system—without closing their positions.
This upgrade is part of OKX’s broader initiative to reduce risk exposure, improve market fairness, and enhance platform stability. To further incentivize the transition, the exchange has adjusted position limits on the legacy mode and introduced a gradual increase in trading fees for continued use of the older system.

Why the Shift to Graded Margin Mode?
Graded margin mode offers several key advantages over the legacy single-liquidation model:
- Lower risk of full position liquidation
- Higher position limits at equivalent leverage levels
- More flexible leverage options
- Reduced cost of trading due to lower fees
By distributing margin across multiple tiers based on position size, graded margin reduces the likelihood of cascading liquidations during volatile market conditions—a common pain point in the older model.
Updated Position Limits in Legacy Mode
To encourage migration and reduce systemic risk, OKX has reduced maximum position sizes under the legacy (single liquidation) mode. These changes took effect on June 6, 2019, at 16:00 HKT.
1. Cross-Margin – 10x Leverage
- When maintenance margin rate is between 100% and 200%, maximum total position size for BTC contracts is 100,000 contracts, including open positions and active orders across all BTC delivery contracts.
- When maintenance margin rate is 800% or higher, the maximum increases to 1,000,000 contracts.
2. Cross-Margin – 20x Leverage
- Similar scaling applies, with tighter caps to reflect higher leverage risk.
3. Isolated-Margin – 10x Leverage
- For isolated margin positions at 10x leverage (e.g., long BTC quarterly contract), the maximum position size per contract is capped at 100,000 contracts.
4. Isolated-Margin – 20x Leverage
- Even stricter limits apply at 20x to minimize potential default impact.
These adjustments mean that traders relying on large positions under the legacy system will now face tighter constraints—making the move to graded margin not just beneficial, but increasingly necessary.
Gradual Increase in Legacy Mode Trading Fees
Starting June 17, 2019, at 12:00 HKT, OKX implemented a 20% fee surcharge on all trades executed under the legacy single-liquidation mode. This isn't a one-time change—fees will increase weekly by another 20% (compounded) until they reach double the rate of graded margin mode.
Fee Comparison Example:
| Mode | Base Maker/Taker Fee | Post-June 17 Fee (Week 1) | Final Target Fee |
|---|---|---|---|
| Graded Margin | Standard rate (e.g., 0.02%/0.05%) | Unchanged | Standard |
| Legacy Mode | Same base | +20% | Up to 2x graded margin fees |
This phased approach gives users time to adapt while clearly signaling the platform’s direction: the future belongs to graded margin.

Benefits of Upgrading to Graded Margin Mode
Switching isn’t just about avoiding higher fees—it’s about unlocking better trading performance:
- ✅ Lower liquidation risk: Margin is allocated across tiers, so only parts of large positions are at risk during volatility.
- ✅ Higher position capacity: Even at the same leverage level, you can hold larger positions.
- ✅ Flexible leverage scaling: Adjust leverage dynamically without being forced into early liquidation.
- ✅ Cost efficiency: Enjoy unchanged, competitive fee rates.
Users who switch retain full control over their open positions and can continue trading immediately—no need to close or re-enter positions.
Frequently Asked Questions (FAQ)
Q: Can I switch from legacy mode to graded margin if I have open positions?
Yes. As long as you have no active limit orders, you can directly migrate your open positions from legacy mode to graded margin mode without closing them.
Q: What happens if I don’t switch to graded margin mode?
You’ll continue trading under tighter position limits and face rising fees. Over time, this makes the legacy mode increasingly costly and restrictive. Eventually, OKX may fully phase out support for the old system.
Q: Does the fee increase apply to both maker and taker orders?
Yes. The 20% weekly surcharge applies to both maker and taker fees in legacy mode until the maximum differential (2x) is reached.
Q: Are these changes permanent?
Yes. The position limit reductions are already in effect, and the fee escalation schedule is fixed starting June 17, 2019. There are no plans to reverse these policies.
Q: How do I check which margin mode I’m using?
Log into your OKX account, go to the futures trading interface, and look for the margin mode indicator next to your position. You can change it via the settings menu if eligible.
Q: Will my unrealized P&L be affected when switching modes?
No. Switching from legacy to graded margin does not impact your entry price, unrealized profit/loss, or current leverage. It only changes how margin is calculated and allocated.
Strategic Implications for Traders
For active derivatives traders, these updates represent more than just policy changes—they signal a maturation of risk infrastructure on digital asset platforms.
The move toward graded margin systems aligns OKX with global financial standards seen in traditional futures markets. By segmenting risk and enabling granular control over collateral usage, such models help prevent systemic shocks during black-swan events.
Moreover, reducing reliance on a fragile single-liquidation framework makes the entire ecosystem more resilient—protecting both individual traders and the broader market.
Final Thoughts: Adapt Now, Trade Smarter
OKX’s rollout of graded margin mode marks a pivotal moment for contract traders. With lower fees, higher limits, and better risk distribution, there’s little reason to stay on the outdated system.
The phased fee increases act as a clear nudge: migrate now or pay more later.
As OKX continues refining its product suite, expect further innovations focused on safety, transparency, and user empowerment. For now, the message is simple—upgrade your margin mode and future-proof your trading strategy.
