v3 Maximum Position Sizes | dYdX v3 Help Center

In order to ensure the safety of the exchange, each market has a maximum position size and a function which determines the margin requirement at different position sizes.

Key Definitions:

incrementalInitialMarginFraction

The increase in the initial-margin-fraction for the market for each incrementalPositionSize that the user is over the baselinePositionSize.

incrementalPositionSize

The position size between each tick of incrementalInitialMarginFraction

baselinePositionSize

The largest position size without incrementing the initial-margin-fraction

maximumPositionSize

The absolute largest position size available

The initial margin starts with 5.0% (for 20x leverage trading of ETH and BTC markets) or 10% for all other markets. After reaching the baselinePositionSize, the required margin linearly increases by the incrementalInitialMarginFraction per incrementalPositionSize
