I know that the risk-neutral price of a call option with strike price $K$ is given by: $$C(K,S_T) = e^{-rT}\int_{0}^{\infty }(S_T-K)^+g(S_T)dS_t$$ Since a payoff is only valid when $ S_T >K $ this turns into: $$C(K,S_T) = e^{-rT}\int_{K}^{\infty }(S_T-K)\times g(S_T)dS_t$$ Now I wanted to differentiate the call formula once and twice with respect to K, so $\frac{\partial C}{\partial K}$ and $…

Background I am trying to calculate the returns on a sequence of trades performed by an entity, where I do not know the starting capital. Therefore I assume a starting capital of zero. From these returns I want to calculate the Sharpe ratio of a portfolio on which these trades are performed. The initial idea of simply comparing successive portfolio values to calculate returns falls apart in this …

Every quant developer knows the feeling: you write an algorithmic strategy, run it against a basic backtesting script, and the equity curve looks like a flawless, vertical rocket ship. You feel like a market genius. But then you deploy that exact same strategy against a high-fidelity system—or live capital—and it immediately bleeds money. What happened? The strategy worked perfectly on paper beca…

The intrinsic value of a call option is found by subtracting the discounted strike price from the current share price: $IV = S - X/e^{rT}$ Put-Call parity: $S + p = c + X/e^{rT}$ $c = p + (S - X/e^{rT})$ Since the second term is literally the definition of the intrinsic value of a call, should the time value of the call option $(c-IV)$ be equal to the value of a put with the same strike price??? …

Is it possible to construct a central bank meeting date curve, using futures prices & OIS rates, in QuantLib? Specifically, I mean a yield curve with flat (constant) forward rates in between meeting dates, and discontinuous moves on meeting dates (or 1 day after I guess, given that typically the rate change applies the next day). If so, how?

In the hyper-competitive landscape of quantitative finance, raw LLMs are fundamentally ill-equipped for rigorous, fault-intolerant environments.

I am implementing the layer-by-layer calibration of the time-dependent SABR model described in Hagan, Lesniewski and Woodward, Managing Vol Surfaces . In particular, I am using the effective-parameter formulas around equations (3.7)–(3.8) and the piecewise-constant integral update formulas in equation (3.11) of the paper. For each expiry $T_j$ , I first calibrate a standard SABR smile and obtain …

Almost every strategy that dies in production looked great in a backtest. The backtest wasn't unlucky — it was wrong, in one of three specific, detectable ways. Here's each one, the exact test that catches it, and why your usual metrics never warn you. 1. Lookahead bias — the silent killer It's almost never a deliberate shift(-1) . It hides in subtle places: Structural indicators computed over th…
