When testing a trading strategy on historical data, you need to specify a concrete period for your training set (e.g., AAPL stock’s price in the period 2020 – 2021). The reason for testing a strategy over different periods is to validate its reliability and mitigate the role “randomness” plays in the whole process. Most traders have several trading strategies, depending on the market situation (downtrend/uptrend), type of asset, risk/profit potential, and more. Understandably, you should make sure to test all your strategies and evaluate their performance. Paper trading, on the other hand, simulates deals in real-time settings without risking any real money.
By testing your strategies against past price movements, you can gain incredible insights into how they would have performed and whether they have the potential for profitability. In other words, it’s like a crystal ball that helps you fine-tune your approach, spot weaknesses, and optimise your decisions before you even risk a single dollar. A trader should not assume a strategy is robust because it has been backtested under one set of input parameters and tested against historical data. One way to gain confidence in the robustness of a trading strategy is testing it against historical data divided into in-sample and out-of-sample buckets. The backtest results computed in the in-sample data can be compared with the results from out-of-sample data. A great trading strategy will have consistent performance across both samples.

You need to backtest your trading strategy to be aware of how it will perform under real market scenarios. Backtesting allows you to simulate your trading idea using historical data and put its risk management mechanisms to the test. Overfitting refers to excessively optimizing a trading strategy to perform well with historical data but potentially fail in real-world conditions.
