How Greeks Stay Current

Most option contracts trade infrequently. An underlying like AAPL might have 5,000+ listed contracts, but only a fraction see active quoting at any moment. Greeks computed from the last trade quickly become misleading as the underlying moves.

Lavender solves this by repricing every contract continuously — recomputing implied volatility and Greeks from the current underlying price and market conditions rather than waiting for the specific contract to trade. The full universe of ~6,000 optionable names ticks continuously during market hours.

Confidence

Each root carries a confidence score (0–1) indicating how well the Lavender model fits the available market data. Names with wide bid/ask spreads or thin quoting are still returned but with lower confidence, so consumers can filter or weight accordingly. The confidence value is available via the confidence field in the Lavender API.
