Stock Trading Technology & Digital Applications 3 — Questions and Answers
Question 1: What is 'paper trading' used for in modern trading platforms?
- Filing physical trade confirmations with the SEC
- Practicing trading strategies with simulated money without real financial risk (Correct answer)
- Trading pink sheet stocks not listed on major exchanges
- Recording trades in a physical trading journal
Correct answer: Practicing trading strategies with simulated money without real financial risk
Paper trading lets traders test strategies using simulated accounts that mirror real markets without risking actual capital.
Question 2: Which of the following best describes 'smart order routing' (SOR)?
- A broker manually selecting the best exchange for each trade
- Automated technology that finds the best available price across multiple trading venues (Correct answer)
- An AI that predicts future stock prices
- A method to route orders to avoid SEC reporting
Correct answer: Automated technology that finds the best available price across multiple trading venues
Smart order routing automatically searches multiple exchanges and dark pools to find the best price and liquidity for an order.
Question 3: A stock screening tool filters equities by P/E ratio, volume, and 52-week high proximity. What is the trader primarily doing?
- Technical charting
- Fundamental screening combined with technical filters (Correct answer)
- Arbitrage identification
- Dark pool order flow analysis
Correct answer: Fundamental screening combined with technical filters
Using both valuation metrics (P/E) and price-action filters (52-week high) combines fundamental and technical screening approaches.
Question 4: What risk does 'overfitting' pose when developing an algorithmic trading strategy?
- The algorithm executes too many trades per second
- The strategy is optimized for historical data but fails on live markets (Correct answer)
- The strategy is too simple to be profitable
- The algorithm cannot handle volatile markets
Correct answer: The strategy is optimized for historical data but fails on live markets
Overfitting occurs when a model is tuned too precisely to past data, making it perform poorly on new, unseen market conditions.
Question 5: Which platform feature allows traders to set a rule like 'sell all holdings if portfolio drops 5% today'?
- Conditional orders or automated rules engine (Correct answer)
- Market-on-close order
- Trailing stop on individual positions
- Portfolio rebalancing scheduler
Correct answer: Conditional orders or automated rules engine
Conditional or rules-based order engines let traders define portfolio-level triggers that automatically execute trades when conditions are met.

- Repairing broken trades that failed to settle
- A standardized electronic communication protocol for exchanging trade-related messages (Correct answer)
- A method for fixing erroneous trade prices post-execution

Correct answer: A standardized electronic communication protocol for exchanging trade-related messages
FIX (Financial Information eXchange) is an industry-standard messaging protocol used to transmit orders, executions, and trade data between institutions.
Question 7: A mobile trading app shows a 'circuit breaker' warning on a stock. What does this indicate?
- The stock's mobile data feed has been interrupted
- Trading in the stock has been temporarily halted due to extreme price movement (Correct answer)
- The company has filed for bankruptcy protection
- The stock's options have expired worthless
Correct answer: Trading in the stock has been temporarily halted due to extreme price movement
Circuit breakers temporarily halt trading in a stock or market when price moves exceed predefined thresholds to prevent panic-driven crashes.
