    Surface viz clicked

    Watching SVI fit stabilize across expiries was a chef’s kiss moment. My backtests finally made sense.

    Powerful, dev-first

    I felt impressed by SVI surfaces and historical replay. No front-end is a bummer for non-coders, and Pro cost is steep. For quants, worth it.

    Greeks in one call

    Spun up an API key and had delta to ultima plus exposures in minutes. Docs are clean, speed is snappy. Pricey at the top tiers, but data depth rocks.

    0DTE data came alive

    I hit the endpoint and watched my model finally breathe. That little aha carried me through the backtest sprint.
