Cross margin vs isolated margin
dYdX allows you to trade perpetuals with up to 20X leverage. Leverage is based on account equity. Depositing USDC collateral increases equity, as does an increase in the value of your positions.
Leverage enables you to buy contracts at a multiple of your trading collateral, increasing both your potential gain and the risk of loss.
dYdX employs a cross margin strategy, where all positions share the same collateral pool. Profitable positions offset losing positions, and the available leverage is based on the total equity in your account.
Initial margin is the minimum amount needed to open a new position. A decrease in the value of your positions or a withdrawal of collateral will reduce your margin. Your maintenance margin is the minimum amount needed to avoid a liquidation.
In contrast, isolated margin assigns specific collateral to each position and can be achieved on dYdX by creating separate accounts for each position.
