The liquidation of large positions poses great risks to other traders. In addition to violent price fluctuations it may bring, some traders may experience autodeleveraging. Binance JEX imposes risk limits on all futures accounts to reduce the possibility of large positions being liquidated. The highest leverage you can use is determined by your position size. The larger your position is, the lower leverage you are allowed to use.
As the size of your position increases, you may be required to decrease the leverage you use. For positions with higher risk limits, a higher percentage of maintenance margin will be required. Let’s take BTC as an example. The base risk limit for BTC contract is 2,000 K USDT, and the base maintenance margin rate is 0.5%. For every increment of 1,000 K USDT in risk limit, maintenance margin rate increases by 0.5%.

Slider to adjust the leverage used can be found in Position column as shown below.
The risk limit shown in the picture above is the maximum contract value you are allowed to hold using the current leverage.
The maintenance margin rate shown in the picture above is the maintenance margin rate required when your contract value reaches the maximum value allowed.
A window requiring you to decrease the leverage used will pop out if the sum of your existing position value and the new order value surpasses your current risk limits. You will need to decrease leverage manually to increase risk limits before you are allowed to resubmit the order.

Introduction 
Example 
Initial Margin Rate 
Used to calculate the initial margin required to open a position 
If a trader uses 50× leverage to open 10 BTC contract, Initial Margin Rate=1/50=2% 
Maintenance Margin Rate 
Increment Times = Roundup (Position Size * Avg. Entry Price  Base Risk Limit ) / Incremental Risk Limit Maintenance Margin Rate = Base Maintenance Margin Rate + Increment Times * Incremental Maintenance Margin Rate

If a trader holds 350 BTC contract, and his/her average entry price is 10,000 USDT, Increase Times = Round up (350*10,0002,000K)/1000K =2 Maintenance Margin Rate=0.5%+(2*0.5%)=1.5% 
Maintenance Margin 
Avg. Entry Price * Position Size * Maintenance Margin Rate 
If a trader holds 350 BTC contract, and his/her average entry price is 10,000 USDT, Maintenance Margin = 10,000*350*1.5%=52,500 USDT
