Finance, in motion
A growing library of short animated lessons, hand-coded frame by frame in Python. Each video is under five minutes, designed for a single lecture beat. Where a lesson maps to an Atlas concept, you can jump from the video into formulas, worked examples, and a quick check quiz.
What Is an Option? Calls, Puts, and the Premium
An option is the right but not the obligation to buy or sell at a fixed strike. Calls, puts, the premium, and why the buyer loss is capped.
IRF vs FRA: a five-axis comparison
Interest Rate Futures versus Forward Rate Agreements compared across venue, standardisation, margin, regulation, and liquidity.
Put-Call Parity, the hidden link between every call and put
Why a call plus a bond equals a put plus a share, the parity equation, and the riskless arbitrage when it breaks. European options only.
Call Options, the right to buy and how leverage cuts both ways
A call is the right, not the obligation, to buy at the strike. Payoff, profit, breakeven, and why leverage cuts both ways, with a worked CBA example.
Futures Payoff, a straight line and a perfect zero-sum game
The simplest derivative payoff. Long is the price minus the entry, short is the mirror, no premium, and every dollar one side makes the other loses.
Risk-neutral Probability, the weight that prices options without forecasts
The artificial weight that makes the discounted stock grow at the risk-free rate. Not a forecast, and the reason an option price ignores where the stock is headed.
Interest Rate Swaps, swap the payments, never the principal
Two parties exchange fixed for floating interest on a notional. Only the net moves each period, the notional never does, and the swap starts at zero value.
Black-Scholes-Merton, one formula that priced the option market
A continuously hedged stock-and-bond portfolio replicates an option, so it has one no-arbitrage price, and the expected return of the stock drops out entirely.
Which concept should be animated next?
The animation queue is open. Tell me which Atlas concept would be most useful as a video — Black-Scholes intuition, binomial backward induction, delta hedging, anything you find hard to picture from text.
