This marks an early step in AIQ Markets’ effort to bring AI tools to the U.S. corporate bond market.

While you're manually checking if YES + NO = 1 , quantitative systems are solving massive constraint satisfaction problems across thousands of correlated markets in milliseconds. The Hidden Reality of Prediction Market Arbitrage You see a market where YES is trading at $0.62 and NO at $0.33. You think: There's $0.05 of arbitrage here . You're right. What you don't see is that by the time you plac…

Why would a bonds discount margin widen but its price increase? Shouldn't the price be falling when margins are widening? Looking at the bond pricing formula, if the price is higher doesn't the rate of return have to be lower? What am I missing?

I am genuinely interested in understanding a little more about the risk aggregation approaches that are out there. I have been recently working on building an operational risk model under Basel 3.1, where the following approach applies. Risks are being modelled via LogN distributions (with the option to use Weibull or Pareto). Given there is no data history, an optimistic and a pessimistic loss i…

I am working on vol surface modeling for cryptocurrencies and generally find that SABR calibrates to the vol surface on ETH better. I know that eSSVI ensures arbitrage free surfaces and therefore that we sacrifice a bit of goodness of fit for it, while SABR isn't guaranteed to be arbitrage free when interpolated, but even by adding safeguards and penalties to SABR to push the general surface towa…

I'm new in quant math, I'm self-studying it. I have two question in exp. daily range topic. How can we make the possibly most accurate estimation for expected daily ranges? My idea was to take data from yahoo finance, calculate realized vol using garman-klass-yang-zhang formula, then use a model (dunno which one) to calculate an expected trailing seven days avg historical vol for SPX. After that …

If you've written a crypto backtester, there's a decent chance one line in it is quietly wrong. It's not the slippage model, not the funding rate, not the fill logic. It's the fee. I've reviewed a lot of grid-bot and market-making backtests over the past couple of years, and the fee handling falls into three buckets, roughly in order of how common they are: fee = 0.0 # "I'll add fees later" (you …

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 $…

Financial charts often combine metrics that live on completely different scales. For example: company revenue measured in billions of dollars, stock prices measured in tens or hundreds of dollars. I wanted to recreate the infographic style seen on Visual Capitalist using pure Python and SVG. The chart combines: annual revenue as bars, monthly stock prices as a line, a secondary axis, a clipped gr…

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??? …

The SEC EDGAR API is one of the best-kept secrets in financial data engineering: every mandatory disclosure filed by every U.S. public company, available as clean JSON, for free, with no API key. If you've ever paid for a "fundamentals" data vendor or scraped a brokerage page for a balance sheet, you've been working harder than you need to. The raw, authoritative source — quarterly revenue, insid…
