Backtesting Vs Scenario Analysis Vs Forward Performance
The performance of a trading strategy can be evaluated using various techniques, such as forward performance, scenario analysis, and backtesting. Each of them has their own advantages and disadvantages, however, because they use different techniques and have different goals.
Backtesting
Backtesting an investment strategy is the method that allows it to be tested on historical data to verify its efficacy and discover any possible issues. The aim of backtesting is to recreate how the strategy might perform in the past if it was used.
Benefits
Improved strategy design - Backtesting lets traders refine and enhance strategies by identifying inefficiencies and weaknesses, before implementing them into live trading.
Backtesting is an objective method of evaluation. It provides a systematic and objective way to evaluate a strategy that removes biases, subjective beliefs and emotions out of the process of making decisions.
Disadvantages
Quality of data - Results from backtesting are affected by the data you use. So it is essential to be sure the data you use is reliable and accurate.
Overfitting- When a plan is optimized too strongly for historical data, it may result in inadequate performance when used with new data.
The absence of real-world conditions- Backtesting is not always accurate. Unexpected events and slippage can have an effect on the performance.
Scenario Analysis
Scenario Analysis aids in assessing the potential impact of different market conditions on trading strategies. Scenario analysis helps to determine the risk-reward proportion of a trading strategy for various market conditions.
Benefits
Improved risk management: Scenario analysis could assist traders to identify and manage the risk that may be associated with strategies, including large drawdowns of periods with lower returns.
Accuracy improves- Scenario analysis will help you determine how your strategy could work in different markets.
Advantages
Limited scenarios - Scenario analysis may only be conducted with a limited set of scenarios. They may not be able to cover every market condition.
Subjectivity - Scenario analysis can be subjective and can be affected by assumptions and personal biases.
Forward Performance
Forward performance refers to the evaluation and analysis of a trading system using real-time data. It is used to evaluate its performance during live trading. The goal of forward performance is to validate and verify scenario analysis results, and to demonstrate that a strategy works in real-world conditions.
Advantages-
Real-world validation- Forward performance is a real-world test of the strategy's effectiveness and helps to identify any issues that might not have been obvious in backtesting or analysis.
Improved confidence - Trading may be more confident about the effectiveness of a strategy through testing it with live data. This allows traders to make informed decisions about the strategy's application.
Disadvantages-
Limited data- Forward performance could be affected by the availability of real-time information which might not accurately reflect the market's conditions.
Emotional impact- Emotional aspects could have an influence on performance. For instance, the fear of losing money can affect decisions.
Each approach is distinct and each one can be used to assess a trading system more deeply. Combining different strategies can aid in validating backtesting and scenarios analysis, as well as ensure that a strategy can be used in real-world circumstances.
