Given an initial leverage and existing position & open orders,
To free up some margin occupied, users are allowed to increase the leverage but it is up to the Max Leverage according to the existing “Oder-Adjusted Position Size”.
To be more risk conservative, users are also allowed to decrease the leverage (which will need more margin for the current position and open orders), but it is up to margin balance.
The following are some examples:
| Example 1 | Example 2 | Example 3 |
Max Leverage
| (1) Initial leverage = 30
(2) Current Size = 70 BTC In Tier 3, Max Leverage = 33.33
Only allow to increase up to 33.33 | (1) Initial leverage = 30
(2) Current Size = 25 BTC In Tier 2, Max Leverage = 40
Only allow to increase up to 40 | (1) Initial leverage = 30
(2) Current Size = 5 BTC In Tier 1, Max Leverage = 50
Only allow to increase up to 50 |
Min Leverage | Need to guarantee: Mark Price * Size / New Leverage <= Margin Balance Therefore Min Leverage = ( Mark Price * Size ) / Margin Balance |
|
|
Note:
The size in the above refers to the “Oder-Adjusted Position Size”.
If there are multiple products in the portfolio, the Margin Balance for determining the minimum leverage of a specific perpetual or future should exclude the IMs occupied by other products.
