## Variation Margin Calls

Variation margin calls are periodic requests for additional collateral from a trader when the market value of their open position moves against them. This process ensures that the value of the collateral backing the position remains sufficient to cover the current mark-to-market loss.

If the trader fails to provide the requested funds, the position is typically liquidated to prevent further losses to the system. This practice keeps the exposure of the clearinghouse or counterparty within acceptable risk limits.

It is a cornerstone of the daily settlement cycle in futures and options markets. By adjusting for daily price changes, the system prevents the accumulation of large, uncollateralized debts.

This mechanism forces traders to acknowledge and account for their losses in real-time. It is vital for maintaining the solvency of the exchange and the confidence of all market participants.
