The document asks whether Visual Basic can handle an order-routing calculation budget of about one millisecond, with much greater time expected for communication to and from exchanges. The replies distinguish modern Visual Basic .NET from older Visual Basic…
The document explains how to interpret the sample count in the two-scale realized variance estimator (TSRV) and why the estimate can be negative. It treats n as the number of intraday observations over the interval being studied, rather than as a fixed count…
This note discusses selecting the tuning parameters for the Two-Scale Realized Volatility estimator. It describes setting the lag parameter to one in the cited extension for dependent noise, and choosing the subsampling parameter as a constant times the…
The discussion examines how market-data latency affects order decisions and claims about market efficiency. When order book updates arrive faster than a non-colocated trader can receive information and send an order, the displayed book may no longer reflect…
The document lists potential sources for historical foreign exchange tick data, including TrueFX, Dukascopy, TickStory Lite, and HistData.com. It presents Dukascopy as an option for downloading hourly data files, either through a website or direct scripted…
The document introduces pre-averaging as a way to address microstructure noise in high-frequency observations of an underlying price process. It defines a statistic as a weighted sum of consecutive price increments, with weights obtained by evaluating a…
The document asks whether exchanges match orders continuously or at scheduled times. Its answer says there is no universal rule across all venues, but describes major developed-market exchanges as generally using continuous-time matching. In that setting, an…
The document asks how to measure “viscosity” in financial time series and considers whether extremes in a simple close-to-close price-change divided by volume measure could represent low or high ease of movement. The replies distinguish this elementary…
The document explains how to search academic work on strategies that exploit knowledge of clustered orders. It distinguishes stop orders, which are not publicly displayed, from visible limit orders in the order book. For visible liquidity and imbalances, it…
The document proposes estimating equilibrium exchange rates across three traded asset pairs without simulating arbitrage trades through every order book. It formulates a constrained optimization that minimizes the volume-weighted squared deviations between…
The answer explains why published deep learning results in trading are relatively scarce and why performance depends on the market and available data. It argues that rich equity data, including news and company information, may support more complex models,…
The document challenges a claim that a high-frequency trading bot can detect a large cryptocurrency order, infer its hidden maximum price, buy available coins first, and resell them at that limit. The answers explain that a marketable order generally…
The discussion distinguishes short holding periods from true high-frequency trading. It describes HFT as requiring rapid market-data processing and order execution, often on microsecond timescales, while commenters report that Interactive Brokers’ API…
The document discusses a three-class LSTM model for predicting financial trends from three time series. The question compares reported accuracy in a cited study with a lower result from an initial implementation and asks about model choices. The response…
The document addresses a measurement problem for high-frequency trading: a return-based Sharpe ratio can be hard to define when the amount of capital deployed is unclear. The question considers whether posted margin can serve as the capital base or whether a…
The document asks how to classify the direction of option trades using tick-level trade and quote data. The proposed workflow is to align trade records with contemporaneous call and put quote panels by option symbol and timestamp, then compare each trade…
The document offers interview questions for candidates evaluating a quantitative trading group, especially when moving from academia into industry. Suggested topics include the markets traded, how research ideas become production models, constraints on…
The document considers vendors for global equity trade bars at intraday frequencies, with the goal of researching short-horizon market patterns and using live data to trade resulting strategies. It identifies historical coverage, a real-time feed, and access…
The document points readers seeking current research on foreign-exchange market microstructure toward high-frequency trading studies. It argues that faster trading has changed how participants trade, how markets are organized, and how liquidity and price…
The document explains “getting picked off” as an informal market microstructure term rather than a condition with a universal empirical definition. In high frequency trading and market making, it often refers to a faster, better informed participant trading…
The document explains an expectation used in a limit-order-book model with an underlying stock-price process driven by Brownian motion. It focuses on how to transform an exponential utility expression involving the terminal price into a form that can be…
The document surveys the search for public measurements of electronic FX liquidity-provider response times, especially the far tail of last-look hold-time distributions during volatility spikes. It describes existing sources as incomplete: an older TCA study…
The document compares options for asynchronous, non-blocking TCP and UDP networking in C++, framed around low-latency and real-time development. It notes that standard networking support was expected in C++17 and presents Boost as a way to abstract…
The document explains the microprice, a weighted average of the best bid and ask that gives greater influence to the side with less displayed volume. With more size at the bid, the resulting estimate moves above the ordinary midpoint. The discussion…
