## Distinguish between ‘Historical Volatility’ and ‘Implied Volatility’.

Historical Volatility (HV) is a backward-looking measure, calculated from the past price movements of the underlying asset over a specific period. Implied Volatility (IV) is a forward-looking measure, derived from the current market price of an option.

IV represents the market's expectation of future volatility and is a crucial input for option pricing.

The beige element suggests historical data points or initial parameter settings, perhaps analogizing legacy collateral management systems. Conversely, the bright cyan mechanism represents the deterministic, programmatic nature of decentralized exchanges facilitating complex options strategies like volatility arbitrage or synthetic asset replication through smart contract deployment. The integration point suggests slippage control mechanisms or automated order routing efficiency crucial for minimizing execution risk across disparate liquidity pools.
