Ask Claude or another assistant in plain English. It calls our tools.
"How did NVDA skew move?"What this costs to build yourself.
The same coverage, built in-house. Every line shows its assumption and source, so you can check it.
Market-maker-grade data used to need a market maker's budget.
The firms that price options for a living spend tens of millions of dollars a year on market data and technology, and the people who have built this at the frontier are rare. That's why this quality hasn't been available to most institutions, let alone individual traders. Everyone is forced to try to reinvent the wheel without knowing how to make a good one. OptionSpace changes that.
The to-do list you won't have.
All of this runs on our side, every day. Doing it yourself costs more than a year of Pro before you've fitted a single smile, even if you know exactly how.
