Traders will be able to see key details about a market.
Tick Size: Each market has a specified tick size. This is the minimum price movement on the market.
Step Size: Step size is the smallest factor allowed for order amounts on the market.
Minimum Order Size: Minimum order sizes vary by asset.
As part of the default settings on the v4 open source software, each market has two risk parameters, the initial margin fraction and the maintenance margin fraction, which determine the max leverage available within that market. By default, these are used to calculate the value that must be held by an account in order to open or increase positions (in the case of initial margin) or avoid liquidation (in the case of maintenance margin).
Maximum Leverage: Each market has a specified maximum leverage. A trader cannot make a trade that would place their leverage above this limit. To limit risk, maximum leverage decreases linearly with position size after a certain threshold.
Maintenance Margin Fraction: Margin fraction is calculated as a trader’s position notional value divided by equity. If a trader’s margin fraction exceeds the maintenance margin fraction, their position will be automatically closed (liquidated) and a liquidation fee of at least 1% will be assessed (may be higher depending on liquidity at the time of liquidation).
Base Initial Margin Fraction: Margin fraction is calculated as a trader’s position notional value divided by equity. If a trader’s margin fraction exceeds the initial margin fraction, a trader will no longer be allowed to increase their position. To limit risk, the initial margin fraction increases by the square root of position size divided by Base Positional Notional multiplied by Base Initial Margin Fraction.
Base Position Notional: The maximum position size at which the margin requirements are not increased.
