## Introduction

Understanding your strategy trades in detail is key to attributing performance, and determining areas to focus for improvement. This analysis can be done with the QuantConnect API. We enable you to load backtest, optimization, and live trading results into the Research Environment.

## Backtest Analysis

Load your backtest results into the Research Environment to analyze trades and easily compare them against the raw backtesting data. For more information on loading and manipulating backtest results, see [Backtest Analysis](https://www.quantconnect.com/docs/v2/research-environment/meta-analysis/backtest-analysis.md).

## Optimization Analysis

Load your optimization results into the Research Environment to analyze how different combinations of parameters affect the algorithm's performance. For more information on loading and manipulating optimizations results, see [Optimization Analysis](https://www.quantconnect.com/docs/v2/research-environment/meta-analysis/optimization-analysis.md).

## Live Analysis

Load your live trading results into the Research Environment to compare live trading performance against simulated backtest results, or analyze your trades to improve your slippage and fee models. For more information on loading and manipulating live trading results, see [Live Analysis](https://www.quantconnect.com/docs/v2/research-environment/meta-analysis/live-analysis.md).
