Data quality is crucial because inaccurate or incomplete data can lead to misleading results, which may result in poor trading decisions. High-quality data helps to simulate realistic market conditions.
How can overfitting be avoided during backtesting?
Overfitting can be avoided by using a larger and more diverse data set, out-of-sample testing, and not basing the strategy on too many variables or conditions that may not repeat in the future.

Frequent backtesting can ensure that a trading strategy remains viable over time; however, it should not be done excessively. It is good practice to backtest when significant changes occur in the market or when major adjustments are made to the strategy.
