The document raises a market-pricing question about VIX options on futures. It observes that one-dollar-wide vertical spreads marked at half their strike width appear to share approximately the same strike across expirations, even when VIX futures are in…
The question reports that a rateslib SOFR curve calibration fails when weekend dates lack fixings, even though SOFR is not published on weekends. The answer offers a small demonstration using a floating accrual period and two otherwise similar curves: one…
The document explains why VXX’s quoted level need not equal a weighted average of nearby VIX futures, even though its returns are designed to reflect an index based on a rolling futures position. The central distinction is between an investment’s price level…
The document describes an exploratory intraday strategy that buys near the lower Bollinger Band and sells near the upper band. The author reports testing it on E-mini S&P 500 data from 1999 and observing a stretch of profitability, while also noting that the…
The answer explains the wildcard option through the adjustment needed between a Treasury futures position and its associated cash-bond position after the futures settlement price is fixed. It defines the tail as the portion of the basis position associated…
The document frames a high-frequency trading problem in Chinese futures: low liquidity and large price fluctuations make order execution difficult, while market data arrives in half-second updates. The author asks how to predict the next tick or improve…
The document describes one practitioner’s approach to constructing the very front end of a SOFR discount curve. The suggested inputs are short-dated fixed-for-floating SOFR swaps, swaps dated to upcoming Federal Open Market Committee meetings, and on-the-run…
The discussion considers how to estimate an OTC call option price when the underlying commodity future trades farther out than listed options. It suggests using a standard option model such as Black-76, with an underlying futures price and an estimate of…
The discussion distinguishes a producer’s physical sales agreement from a futures position used to hedge the price risk of that sale. A producer may have agreed to deliver oil to a particular refinery at the future spot price; a short futures position can…
The response derives how Heston stochastic variance dynamics connect to a variance swap and then to VIX, whose squared level is treated as the expected average variance over a 30-day horizon. Under a chosen volatility-risk-premium assumption, the…
The document describes an asymmetry in commodity futures pricing for storable goods. If a future contract is priced far above spot, an arbitrageur can buy the commodity now, pay financing, storage, and insurance costs, and arrange delivery against the…
The document offers practical advice to a junior analyst who finds the many concepts and terms used on a bond trading desk difficult to follow. It emphasizes that fixed-income work depends not only on academic knowledge but also on market conventions,…
The document reviews a proposed use of the Parkinson high–low volatility estimator: compare it with a noncentered volatility estimate from open-to-close returns to infer whether price behavior is mean reverting or trending. It recounts Taleb’s stated…
The document offers possible undergraduate research directions related to the VIX and the newer SPIKES index. Suggestions include examining whether the VIX and its futures serve their intended purpose, what a theoretically sound volatility product might look…
The document asks which observations should anchor a proportional adjustment when building a continuous futures series: the expiring contract’s close and next contract’s close on rollover day, or the expiring contract’s prior-day close and next contract’s…
The document explains why different metals can have different futures curve shapes, using copper in backwardation and aluminum in contango as examples. It starts from a cost-of-carry relationship involving financing, storage costs, and convenience yield,…
The document asks where to obtain monthly historical data for WTI, gold, and the CRB index. The answer names free data sources and commercial vendors, but emphasizes that a request for a commodity price needs a more precise definition before choosing a…
The document explains why futures and forward prices can coincide even though futures settle through daily variation margin while forwards settle at maturity. With known, deterministic interest rates, the daily futures cash flows can be scaled and combined…
The document compares the tracking error of an ETF and a futures instrument relative to the same equity index. It measures tracking error as the standard deviation of daily return differences and reports that the ETF’s measured value is larger in the…
This discussion points readers seeking to understand implied pricing in futures markets toward exchange and trading-platform documentation. The questioner found introductory vanilla examples insufficient and wanted clearer explanations of implied orders and…
The document explains how to infer market-implied probabilities of Federal Reserve rate changes from fed funds futures. A basic method converts the futures-implied rate after a meeting into a probability-weighted average of possible outcomes, such as no…
The document considers what to trade with an imagined near-zero-latency program. It argues that speed within one data center is less decisive than the speed of communication between venues, so faster code alone does not confer a general trading advantage.…
The discussion questions whether increased short positions in U.S. Treasury futures could explain rising Treasury yields, given that a futures short may ultimately require acquiring the deliverable bond. One response distinguishes a futures position from an…
The document answers a question about matching a CFTC Commitments of Traders report code to the futures contract it represents. It identifies code 097741 with Japanese yen futures and points to the standard CME 6J contract as the corresponding market…
