The document explains what it means to provide liquidity by posting limit orders that other traders can execute. It highlights the central risk for a trader attempting to make markets: when prices move quickly, an order may fill just as the market moves…
The document describes how to search for arbitrage across many currencies by modeling exchange rates as a directed graph. Each currency is a vertex, and each quoted conversion rate is an edge. Taking the negative logarithm of each rate turns the product of…
The document describes an investor’s attempt to preserve exposure to a UK-listed share by replacing the position with its US dollar ADR. The investor understood each ADR to represent five UK shares and expected to be able to switch back without changing the…
The discussion explains that FX forward points reflect the interest rate differential between two currencies, while the all-in forward price combines spot with those points. Changes in short-term money-market rates and funding conditions affect the points,…
The document is a short reading list for exploring deep reinforcement learning and related machine-learning methods in quantitative finance. It points readers toward work on optimal execution, foreign-exchange trading, price formation, options pricing, and…
The document compares ways to estimate a currency pair’s next-day or intraday price range for purposes such as setting stops. It distinguishes return-based volatility models from high-low range measures, noting that GARCH conventionally models conditional…
The document argues that no single absolute benchmark can establish the quality of every trading algorithm. The appropriate evaluation depends on the algorithm’s role: a signal model, portfolio-sizing process, execution method, or complete automated…
The document reviews research comparing foreign-exchange volatility forecasts from variations of GARCH models. The studies construct realized volatility from squared intraday returns, including adjustments intended to reduce market microstructure bias, and…
The discussion asks whether currencies have a broad passive index comparable to an equity market index, for use in evaluating currency traders. It explains why a universal benchmark is difficult: currency positions are relative long/short exposures, so even…
The document describes an FX option combining an American up-and-out call feature with a European down-and-in put feature. It asks why a market pricer uses a default Vanna–Volga adjustment for this path-dependent structure and whether Monte Carlo is more…
The document frames the construction of an FX volatility surface for pricing vanilla European options and testing systematic option strategies. It focuses on risk reversals, strangles, and butterflies quoted at 10-delta and 25-delta, and on tracking premiums…
The document describes ways to construct an implied volatility smile from standard FX quotes, including at-the-money volatility, risk reversals, and strangles at specified deltas. One approach fits a quadratic curve in delta space, using the at-the-money…
The document explains how to apply covered interest parity when a forward’s fixing date falls before its spot date, a situation that can arise when holidays delay spot settlement. It uses an example involving the Vietnamese dong, where a Lunar New Year…
The document challenges a news explanation that linked a small oil price recovery with a risk-on move in the Australian dollar. Its answer argues that labels such as risk-on, risk-off, risk appetite, and market sentiment lack precise definitions in common…
The document explains what reported volume generally measures and why its meaning depends on the instrument and market. For exchange-listed stocks, volume usually counts shares traded; the monetary value is commonly called turnover or dollar volume. For…
The document explains why FRTB delta sensitivities divide a mark-to-market change by the size of the market bump. For a linear cash equity or foreign exchange position, this scaling makes the sensitivity equal to the position’s mark-to-market value, so it…
The document explains the relationship between FX swap points and cross-currency swaps. It states that a single-period cross-currency swap has the same four start and end principal cash flows as an FX swap, so their fair values are linked. To derive a…
The document explains how currency forward carry relates to the return on a hedged foreign bond. A long position in foreign currency has carry when the spot rate is unchanged at maturity; a hedge against that exposure takes the opposite, short…
The document explains the structure of the U.S. Dollar Index as a weighted geometric basket of six foreign currencies. Its currency exponents correspond to fixed component weights based on bilateral trade, while the leading coefficient sets the index’s…
The document addresses what counts as a day when calculating a momentum oscillator for a currency pair such as EUR/USD. Its answer describes the conventional FX trading week as beginning with the Monday value-date rollover in Wellington and ending at the…
The document asks how to reproduce the profit and loss of a USDCHF position with a stated size of 1,000 by trading USDEUR and EURCHF instead. It notes the triangular exchange-rate relationship: USDCHF is the product of USDEUR and EURCHF. The practical…
The document explains the sharp EUR/CHF move on January 15, 2015, when the Swiss National Bank abandoned its minimum exchange rate against the euro. It describes the floor as a policy intended to limit franc appreciation, and says the bank had maintained it…
The document explains how to represent an FX forward as simpler risk-factor positions for value-at-risk analysis. Its example breaks a contract to buy euros for dollars into a currency spot exposure, a euro bill position, and a dollar bill position. The…
The question seeks literature on how non-financial companies manage commodity and currency price risk in their operating businesses, rather than on speculative trading. The replies offer broad starting points: commodity-market books and the Energy Risk…
