The document clarifies how the monthly average effective federal funds rate is treated when calculating the settlement price of 30-day federal funds futures. Although published effective rates are available only for business days, the contract’s averaging…
The document asks whether futures-market activity can influence spot prices, reversing the familiar explanation in which a supply or demand shock first moves the spot market and then affects futures. It invokes the theoretical relationship between spot and…
The document compares approaches to forecasting intraday trading volume, with particular interest in futures. It highlights recurring patterns linked to time of day, contract rolls, and economic announcements. One approach models trades or volume through a…
The document responds to a question about locating market data needed to price an interest-rate cap on a different trade date. It does not provide Bloomberg navigation steps or explain whether the specific swap data are free. Instead, the answer offers an…
The document addresses how to name a position combining a 5s10s interest-rate swap curve trade with a Treasury curve hedge. The described position pays the 5-year swap and receives the 10-year swap, while buying 5-year Treasuries and selling 10-year…
The document asks whether a trader can enter a futures position with a nonzero initial value by choosing a delivery price below the cost-of-carry level. One response describes a futures-options combination: buying a call and selling a put at the same strike…
The document outlines a beginner’s proposed workflow for sending Interactive Brokers futures data into NeuroShell Trader for live use. It describes NeuroShell’s Data Pump as an interface that lets an external application collect data and pass streams into…
The note examines the volatility term for a spread option under a Bachelier model, where the underlying prices are modeled with arithmetic Brownian motion. The questioner expects the spread’s volatility to combine the two futures volatilities and their…
The document recommends storing options observations in a time-indexed, long-format table, with one row per contract at each snapshot. Useful fields include timestamp, underlying or forward price, strike, expiry, option type, bid and ask, implied volatility,…
The note outlines an approximate way to estimate bond forward prices and carry when the available inputs are government yields by maturity. It proposes treating the observed yields as par yields, so each yield also serves as the coupon rate for a…
The document corrects an argument that a long futures position earns twice the payoff of a forward. The mistaken argument adds the cumulative daily changes in futures prices to an assumed final payment of the initial-to-final price difference. The answer…
The document asks why SVXY recovered only modestly after a sharp volatility spike and subsequent decline in VIX futures. It gives a historical example: the product fell from roughly $140 to $9 and rebounded to about $12, while VIX futures moved from the…
The document explains why end-of-day futures datasets commonly contain exchange business days rather than every calendar day. The key distinction is that end-of-day records often report the exchange’s settlement price, which supports daily profit-and-loss…
The document describes a problem downloading free historical intraday data from Finam.ru: the resulting text or CSV file contains an unintelligible message instead of market data. A reply identifies the message as an error indicating that the requested time…
The document asks how to estimate short-dated implied volatility for options on commodity futures when listed expiries are sparse. Its soybean example contrasts contracts with clearly observable weekly or short-dated option expiries against intermediate…
The document explains why a yield curve may combine cash instruments, interest-rate futures, and swaps: market participants select instruments with active, liquid quotes across maturities, while keeping their credit and funding risks consistent with the…
The exchange explains the discount factor in the value of a forward contract on an asset that pays no income. The contract’s delivery price is fixed when the agreement is initiated, while the forward price can change over time. Their difference represents…
The document works through a market hedge for a 50,000-share stock position using index futures. Given the stock value, futures price, contract multiplier, and a beta of 1.3, it calculates a short position of 26 contracts. The cited textbook solution says…
The document considers how to build a hedge from quarterly short-term interest-rate futures using weights from a first principal component. It normalizes the component weights to one contract month to create a spread representation, then shows how equal tick…
The note derives the futures–forward price difference from the change between the risk-neutral measure and the maturity-forward measure. This difference appears as a covariance between the accumulated funding factor and the terminal index level. For an FX…
The document asks how shorting bond futures to hedge a long bond’s duration affects the position’s interest income and rate exposure. It compares the intuition of retaining a fixed coupon while neutralizing duration with the possibility that the combined…
The document considers why E-mini S&P 500 futures commonly trade with a narrow bid-ask spread. It proposes active competition among participants and the breadth of the underlying index as possible explanations. The responses emphasize the contract’s broad…
The document raises a practical question about backtesting value-at-risk models for portfolios containing instruments with maturities or payment schedules. It asks whether historical contract terms should be shifted backward along with each test date so that…
