Stock Trading Technology & Digital Applications 5 — Questions and Answers
Question 1: What is 'two-factor authentication' (2FA) most important for in online trading accounts?
- Improving trade execution speed
- Adding a second layer of identity verification to prevent unauthorized account access (Correct answer)
- Complying with pattern day trader rules
- Enabling access to margin trading features
Correct answer: Adding a second layer of identity verification to prevent unauthorized account access
2FA requires a second verification step beyond a password, significantly reducing the risk of unauthorized account access and fund theft.
Question 2: Which data feed type provides the most comprehensive real-time market information for active traders?
- Delayed 15-minute quotes
- Consolidated tape (CTA/UTP) full depth-of-book feed (Correct answer)
- End-of-day closing price data
- Weekly earnings estimate consensus data
Correct answer: Consolidated tape (CTA/UTP) full depth-of-book feed
The consolidated tape aggregates real-time trade and quote data from all US exchanges, providing complete market transparency for active traders.
Question 3: A trader notices their limit order was filled in multiple smaller executions at the same price. What likely occurred?
- The broker split the order to charge more commissions
- The order was partially matched against multiple smaller orders on the opposing side of the book (Correct answer)
- The exchange rejected the original order size
- The stock triggered a circuit breaker during execution
Correct answer: The order was partially matched against multiple smaller orders on the opposing side of the book
When no single counterparty can fill the entire order, the matching engine fills it against multiple smaller orders, resulting in partial fills at the same price.
Question 4: What is the primary purpose of a 'trading journal' application integrated with a brokerage platform?
- Automatically filing tax documents with the IRS
- Tracking trade performance, documenting strategy rationale, and identifying behavioral patterns (Correct answer)
- Alerting regulators to suspicious trading activity
- Calculating real-time margin requirements
Correct answer: Tracking trade performance, documenting strategy rationale, and identifying behavioral patterns
A trading journal helps traders analyze their performance, identify mistakes, refine strategies, and eliminate emotional decision-making over time.
Question 5: What risk does using public Wi-Fi pose for traders accessing their brokerage accounts?
- Slower order execution due to shared bandwidth
- Man-in-the-middle attacks that can intercept login credentials and account data (Correct answer)
- Automatic logoff due to brokerage security policies
- Higher margin requirements imposed by the broker
Correct answer: Man-in-the-middle attacks that can intercept login credentials and account data
Public Wi-Fi networks are vulnerable to man-in-the-middle attacks where malicious actors can intercept unencrypted data including login credentials.
Question 6: What does an 'API key' allow a trader to do when provided by a brokerage?
- Access physical branch services remotely
- Connect third-party software or custom algorithms directly to the brokerage's trading infrastructure (Correct answer)
- Unlock premium charting features on the broker's platform
- Transfer funds between brokerage accounts instantly
Correct answer: Connect third-party software or custom algorithms directly to the brokerage's trading infrastructure
API keys authenticate external applications, enabling traders to connect custom algorithms, trading bots, or third-party tools to their brokerage account programmatically.
Question 7: A trading platform sends an SMS alert when a stock hits a set price. Which feature is being used?
- Stop-loss order execution
- Price alert or conditional notification system (Correct answer)
- Automatic order placement at the target price
- Earnings announcement reminder service
Correct answer: Price alert or conditional notification system
Price alert systems notify traders via SMS, email, or push notification when a security reaches a defined price level, without automatically placing a trade.
