This is not a course about buying calls when you think the stock will go up. This is a course about understanding options as instruments of risk transfer — how they are priced, hedged, and traded by professionals.
Phase 1 — Mechanics (Level 2): calls, puts, payoff diagrams, intrinsic and time value, put-call parity, option strategies (spreads, straddles, strangles). 7 units. You understand what options are and how they combine.
Phase 2 — Pricing (Level 3): binomial model intuition, Black-Scholes formula step by step, the five inputs, what each does to the price. 8 units. You can price a European call with pen and paper: S = $49, K = $50, σ = 20%, r = 5%, T = 0.38 → C = $2.44.
Phase 3 — Greeks and Volatility (Level 3): delta (hedge ratio), gamma (hedging frequency), vega (vol sensitivity), theta (time decay), volatility smile, implied vs realised, gamma scalping. 23 units. You think about options the way a desk thinks about them.
The FinLingo Vanilla Pricer is a real-time BSM calculator on your phone. Five sliders: spot, strike, vol, rate, time. All five Greeks update instantly. A payoff chart draws itself below. Move vol from 20% to 25% and watch vega earn $0.15 per share. Shorten time from 6 months to 1 month and watch theta accelerate. This is where formulas become intuition.
Students targeting equity derivatives desks. Junior traders who need Greeks fluency. Career changers who want to speak options language before their first day. Anyone who tried learning from Hull and wants something they can interact with, not just read.
If you know what a stock is and what interest rates are, you have enough foundation. Level 2 starts from scratch with what an option is. If you are a complete beginner, start with Level 1 (free) to build market foundations first. If you already know the basics, jump straight to Level 2.
Level 2 covers the main strategies: spreads, straddles, strangles, and combinations. But FinLingo emphasises the Greeks and vol framework over strategy catalogues. Understanding that a short straddle is short gamma and long theta is more valuable than memorising the payoff diagram of an iron condor.
By making abstract formulas concrete. When you read that vega measures sensitivity to vol, it is abstract. When you drag the vol slider from 20% to 25% and see the option price jump by $0.75, it is real. The pricer turns every formula into a cause-and-effect experiment you can run in seconds.
