Back testing assesses performance of a trading approach by applying it to historical data rather than future data.

• A. It uses only synthetic data
• B. It is a real-time performance monitor
• C. It evaluates performance using historical data
• D. It is not used in strategy development

Answer: (C)

Backtesting evaluates how a trading approach would have performed by running it on historical price data. By replaying past market conditions, you can see how the rules would have triggered trades and what results would have followed, giving insight into profitability and risk without risking real capital. This historical replay lets you measure metrics like returns, drawdowns, and win rate, helping you refine the strategy before live use. Using synthetic data isn’t the main method here because backtests rely on actual price movements to reflect real market dynamics. Real-time performance monitoring, by contrast, tracks results as trades unfold in live markets. And backtesting is a common step in strategy development, not something to skip.
