Get & Adjust Leverage

Bluefin Exchange currently supports Isolated Margining with up to 20x leverage. As such user's have isolated control over each market's leverage.

All orders for a given market must be placed at the same leverage as the user set market leverage.

Get Leverage

The method Get User Default Leverage returns a user's set leverage for a given market. The method takes in the following parameter:

Market Symbol: Symbol of the market in format "{ASSET_SYMBOL}-PERP" eg: "BTC-PERP", "ETH-PERP"

Adjust Leverage

The Adjust Leverage method allows users to update the market leverage.

Note that you should cancel all open orders before updating leverage. This method will force cancel any remaining open orders at the previous market leverage.

Sub Accounts: If trading as a sub account, specify the parentAddress field. Read more about Sub Accounts here.

The method expects the following parameters:

Symbol: Symbol of the market in format "{ASSET_SYMBOL}-PERP" eg: "BTC-PERP", "ETH-PERP"
Leverage: New leverage
Parent Address (optional): Specify parent account if trading as a sub account
