LiFin Lab · Companion tool to The News Desk & The News Desk: Margin Call
The same six stocks, real strikes, and real Black-Scholes premiums as the simulations — but no headline, no clock, no scoreboard. Build any combination of futures and options (buying OR writing), watch the payoff diagram update live, and see exactly how much margin it would tie up.
Now synced to the Margin Call game: each round shows what the 🧠 Instrument-Smart Bot actually traded and earned, and a new Concepts tab explains every term and every strategy from scratch.
