# Historical data selection criteria

{% hint style="info" %}
The accuracy and precision in the backtesting process lies, in large part, in the selection of high-quality historical data. This data is the cornerstone on which our trading strategies are built and evaluated, and any failure at this stage propagates to subsequent stages, leading to inaccurate results.

**Why is careful data selection essential for Smart Trading Indicators?**

## Relevance

In the dynamic world of trading, not all historical data is equally relevant. The market changes and evolves over time, and older data may not reflect the current market conditions. At Smart Trading Indicators, we ensure that the selected data is pertinent and up-to-date. This means that our indicators are not only theoretically sound but also adapt and reflect the realities of the modern market.

## Depth and Diversity

Markets go through different cycles and states: bull markets, bear markets, periods of high volatility, and more. Good backtesting should consider all these phases to ensure that an indicator or strategy can perform under various conditions. Our methodology incorporates extensive datasets that span these cycles, thus ensuring that backtesting results are robust and not biased toward a specific type of market or condition.

## Cutting-Edge Technology

Data, by itself, often comes with errors, omissions, or anomalies. These imperfections, if left untreated, can compromise the integrity of backtesting. At Smart Trading Indicators, we use cutting-edge technologies and sophisticated algorithms to process, clean, and validate historical data. This ensures that the data input into our backtesting system is accurate, consistent, and free from anomalies that could bias the results. Furthermore, our technological tools allow us to analyze and process vast amounts of data in record time, which means we can conduct multiple tests and optimizations in a short period, keeping our indicators at the forefront.

The meticulous attention we pay to historical data selection and treatment underscores our commitment not only to technical excellence but also to transparency and reliability. At Smart Trading Indicators, we understand that every trading decision is based on trust, and we work tirelessly to strengthen that trust every day.
