Free · In‑App Purchases

Train for quant and trader interviews with independent firm-style OA practice, mental math, probability, cognitive games, and progress analytics. Start free. Master your quantitative trading interviews and ace your next Online Assessment (OA). TradeMind is a premium, comprehensive interview preparation platform tailored for quants, traders, and finance professionals targeting top-tier market makers and proprietary trading desks. Go beyond basic preparation. Build your mental stamina, increase your calculation speed, and master complex risk scenarios with high-intensity drills modeled precisely after industry-standard assessments — including realistic, timed replicas of real firms' actual OA formats. CORE TRAINING MODULES Realistic OA Sit a full, timed replica of a real employer's Online Assessment — starting with Chicago Trading Company's (CTC) 50-question, 15-minute mixed format spanning numerical reasoning, spatial/abstract pattern recognition, verbal reasoning, and logic & attention-to-detail, scored exactly like the real thing (no penalty for a wrong guess). Mental Math & Approximation Drill integers, decimals, fractions, and advanced approximation techniques (including Taylor expansions and the Rule of 72) under strict time pressure, then put it to the test in realistic timed simulations of Akuna Capital, Maven Securities, Flow Traders, and SIG's actual assessments. Sequence Recognition Master complex numerical sequence tests with customizable pattern types, including Fibonacci-style, look-and-say, and interleaved dual sequences — plus realistic Optiver, Akuna, Flow Traders, and SIG sequence rounds. Probability & Expected Value Sharpen your statistical intuition with dedicated question banks covering combinatorics, Bayes' theorem, poker odds, and betting EV calculation, backed by realistic Optiver, SIG, Jane Street, IMC, and Quant Circuit assessments. Market Making Simulations Engage in interactive trading games. Evaluate Play/Pass wagers based on Realized PnL, or Quote a Market against an adjusting, smarter counterparty. OA Prep Train the exact behavioural and cognitive paradigms gamified assessments are built from — 16 original games covering risk tolerance, decision-making under uncertainty, working memory, and sustained attention — capped off with a full trait profile report after every run. Cognitive & Logic Games Train the exact memory, flexibility, and attention tasks used in proprietary tests, featuring Pincode memory, Task Switching, and Response Conflict drills. Brain Teasers Sharpen your lateral thinking with a continuously growing library of classic quant interview logic puzzles. Comprehensive Theory Access an extensive reference library covering everything from Interview Meta-Skills and Advanced Probability to Stochastic Processes, Black-Scholes, and ML in Quant Finance. Advanced Metrics & Daily Plans Set a personalized Daily Plan, then track your calculation accuracy, response speed trends, and historical activity streaks with granular data visualization to eliminate weak spots. Whether you are tackling an 80-question speed math test, decoding numerical structures, sitting a full mixed-format Online Assessment, or pricing options under volatile constraints, TradeMind provides the exact framework required to elevate your performance and secure your offer.
