In order to find the best way to backtest a stock trading strategy, you need to first know what a backtester is and does. Backtesting a strategy is a simple concept.

Take an economic event or a sudden shift in price or volatility and compare it to a number of similar situations in the past. Run your trade strategy through all these situations in the past while manipulating several variables. Optimization refers to letting the computer calculate the best combination of the above mentioned variables into a function. Optimizing your backtests can be lead to overconfidence because the best combination of inputs for past situations doesn’t necessarily mean that it will profit in real trading. Side note – Overfitting: A problem that can occur with AI is overfitting.

Overfitting represents a model that correlates too closely with a particular set of data and it contains more parameters than can be justified by the data itself. Machine learning or AI tends to try to maximize its results on a set of data and ignores the suitability for future data. It’s important to be mindful of the possibility of overfitting when you are running a backtest. Gather more data, if you fit a model to twenty past situations, it is much more likely to predict the situation in the future.
