Tradoing: Quant Cards turns dense finance and algorithmic-trading concepts into fast, active-recall flashcards. Instead of passively flipping cards, you actually do the work — spot the bug in a strategy, pick the right tool for a scenario, judge whether a number is plausible, rebuild a formula, put the steps of a process in order, and connect related ideas. Topics span the quant curriculum: • Company fundamentals, ratios and valuation • Macroeconomics and market regimes • Commodities and futures • Technical indicators for backtesting • Options and the greeks • Derivatives beyond vanilla • Crypto and market microstructure • Quantitative finance, risk and backtesting Features: • 360+ hand-written cards across six active-learning mechanics • Spaced repetition — each card comes back right before you'd forget it • Fully offline — study anywhere, no connection required • A searchable reference library of the underlying concepts • Optional sign-in to sync your progress across devices • A daily study reminder to keep your streak going Built for anyone preparing for quant and trading interviews, learning systematic trading, or keeping their markets knowledge sharp.
