Initial Margin Ratios
Initial Margin Ratios determine the amount of collateral a trader must provide to open a new leveraged position. This ratio acts as a down payment, ensuring that the trader has skin in the game and that the exchange is protected against immediate price movements.
The ratio varies depending on the asset's volatility and the leverage selected. A higher initial margin ratio reduces the effective leverage, lowering the risk of liquidation.
It is a key lever used by exchanges to manage the risk of their user base. Traders must understand how these ratios impact their buying power and their potential liquidation price.
Setting these ratios is an ongoing process that responds to changing market conditions. It is the first line of defense for the margin engine.
Understanding these ratios is essential for effective capital management in derivatives trading.
