  1. Chii chinonzi 'overfitting' mumamiriro ekutengesa mhando?
    • Iyo modhi inokodzera ruzha rwenhoroondo uye inotadza pane mhenyu data
    • Kutengeserana mashares akawanda panguva imwe chete
    • Kushandisa yakawandisa komputa memory
    • Kutenga masheya ane mutengo wakawandisa
  2. Ndechipi chinangwa chekutanga chekuuraya algorithms seVWAP neTWAP?
    • Kufanotaura mitengo yegore rinouya
    • Kuzadza maodha mahombe uku uchideredza kukanganisa kwemusika
    • Kuti encrypt data yekutengesa
    • Kubvisa njodzi yese
  3. Sei data yemusika wezvemari ichitsanangurwa se 'isina-yakamira'?
    • Hazvimbochinji
    • Inochengetwa munzvimbo imwe chete
    • Nhamba dzayo dzenhamba dzinochinja nekufamba kwenguva
    • Inogara ichiwedzera
  4. What uncertainty did Busseti and Boyd incorporate into their VWAP execution model?
    • A guaranteed future price for every share
    • A perfect forecast of market-wide returns
    • A signal that removes transaction costs
    • Imperfect knowledge of total market volume during the execution schedule
  5. What data did the cited VWAP execution study use for its simulation validation?
    • Real NYSE market data
    • A guaranteed future price for every share
    • Only synthetic data from a single stock
    • A set of central-bank press releases
  6. What result did Busseti and Boyd report for their simulated VWAP solution?
    • A guaranteed 10% trading profit for every investor
    • A 10% reduction in VWAP-deviation RMSE versus the standard static solution
    • A 10% reduction in losses for every market regime
    • Zero slippage under all order sizes
  7. Why use chronological train and test splits for trading models?
    • To ensure every period has identical prices
    • To increase the number of assets
    • To reduce leakage from future market information into past predictions
    • To remove transaction costs automatically
  8. Why include transaction costs and slippage in a backtest?
    • They always improve returns
    • They are only relevant for HFT
    • They replace out-of-sample testing
    • They can materially change whether a signal is economically usable
