The backtest is the backbone of any good trading strategy development. You get to know what works and what does not before parting with your hard-earned cash. However, not all backtests are created equal, and many common mistakes that you may make can throw off results, leading to terrible live market performance. This guide explains how you should go about backtesting correctly and how to avoid common pitfalls, especially when you're using Tradetron, a trading app in India.
Why Do You Need Backtesting?
Backtesting helps you:
Understand how your strategy works under different market conditions.
Boost confidence in your approach through validation of its historical success.
Save time and money by pinpointing flaws in a controlled environment.
However, faulty backtesting methods may result in false confidence, so it's crucial to understand the process.
How to Backtest Your Trading Strategy Properly
1. Select Reliable Data Sources
Meaningful backtests are founded upon accurate historical data. Otherwise, poor-quality or incomplete data will lead to inaccurate results.
Tip: Use data coming from reputed platforms or the best trading apps in India. On Tradetron we have the best possible data from Jan 2020 onwards.
2. Realistic Assumptions
Your backtest should account for the following:
Transaction Costs: Brokerage fees, taxes, slippage can make a large difference in results.
Latency: Execution delays in live markets are not taken into account in backtests as backtests check conditions once per minute.
3. Overfitting
Overfitting occurs when a strategy is overoptimized on historical data, resulting in poor live performance.
Solutions: Test your strategy over multiple timeframes and markets for robustness.
4. Use Multiple Performance Metrics
Profits/losses alone are misleading. Other key metrics to evaluate include the following:
Drawdowns: Worst-case losses
Win Rate: Percentage of winning trades
Sharpe Ratio: Risk-adjusted return
5. Leverage Backtesting Tools
Many trading apps in India have inbuilt backtesting tools, like in Tradetron which makes testing strategies easier. Platforms such as the best trading app India simplify the process by having user-friendly interfaces and reliable data.
Common Mistakes in Backtesting
1. Failure to Consider Market Realities
Backtesting assumes perfect order execution, but real-world markets have slippage and liquidity constraints.
Solution: Simulate realistic trading environments with adjusted execution conditions.
2. Failure to Consider Market Trends
Markets change: A strategy that applied five years ago may not apply today.
Remedy: Periodically revisit and adapt your strategies to reflect current market conditions.
3. Sample Size Too Small
Testing in a small dataset or a certain time period may lead to biased results.
Remedy: Use a broad range of historical data that covers the various cycles of the market.
4. Confirmation Bias
There is a tendency of traders to cherry-pick data to confirm their hypothesis.
Remedy: Test objectively by checking both the successes and failures.
