Stop Maintaining Your Own SVI Fitting Code — Advanced Volatility API for Quant Teams
If your team maintains SVI fitting code, arbitrage checks, and variance surface infrastructure, FlashAlpha's Advanced Volatility endpoint replaces all of it with a single API call. The Problem This Solves Every quant team that trades options eventually builds a vol surface. The typical stack: Pull raw option chains from a market data vendor Filter out stale quotes, wide markets, zero-OI strikes Fit SVI parameters per expiry slice (and debug when the optimizer doesn't converge) Interpolate across expiries to build the full surface Check for butterfly and calendar arbitrage violations Compute derived quantities: variance swap fair values, higher-order greeks Cache and refresh on a schedule That's 2,000-5,000 lines of code someone has to maintain. When the optimizer breaks on a low-liquidity name, someone debugs it. When OPRA changes a feed format, someone patches it. When a new expiry cycle starts and the calibration window shifts, someone adjusts it. The Advanced Volatility endpoint doe
