Backtesting is an essential part of developing a profitable trading strategy. It allows you to test your strategy on historical data to determine its viability before risking real capital. TradingView has become one of the most popular platforms for backtesting strategies, with its easy-to-use interface and variety of built-in tools. In this comprehensive guide, we'll cover everything you need to know to effectively backtest on TradingView.
What is Backtesting?
Backtesting refers to applying a trading strategy or analytical method to historical data to simulate how a strategy would have performed. By backtesting, traders can evaluate and refine trading ideas and assess the viability of a strategy before risking real money.
Some key benefits of backtesting include:
Overall, backtesting provides an objective method to build confidence in a strategy before deployment.
Why Use TradingView for Backtesting?
TradingView has emerged as one of the most popular online platforms for backtesting trading strategies. Here are some key reasons to use TradingView:
With its combination of usability, active community, and platform flexibility, TradingView has become a go-to platform for traders looking to evaluate and improve their trading strategies.
Step-by-Step Guide to Backtesting on TradingView
Here is a step-by-step walkthrough of how to use TradingView for backtesting:
1. Select the Market and Timeframe
The first step is choosing which market and timeframe to base the backtest on. Common markets available include forex, stocks, indexes, and cryptocurrencies. For timeframe, you can choose from intraday timeframes like 1-minute and 5-minute all the way to long-term weekly and monthly charts.
The market and timeframe should be chosen based on the trading strategy being tested. For example, a day trading strategy would necessitate a short timeframe chart like the 5-minute or 15-minute.
2. Setup the Chart
Once the market is selected, setup a candlestick chart to visualize the price history and serve as the foundation for backtesting. You can also add on indicators, drawings tools, and other chart overlays at this stage if desired.
Be sure to enable the “strategy tester” feature which will show long-term price history beyond what is visible on the chart.
3. Add Your Strategy Logic
There are two main options for adding your strategy rules and logic within TradingView:
Coding a Custom Strategy
For full customization, you can code a trading strategy using Pine Script. The Pine coding language allows you to programmatically define entries, exits, risk management, and anything else required for automated trading.
While powerful, Pine coding requires programming knowledge.
Using the Visual Strategy Builder
The visual strategy builder provides a no-code way of specifying strategy logic. Simply define rules like price crossing a moving average, RSI levels, and more via the UI to build out a complete strategy.
The visual builder is simpler but more limited than coding a custom strategy.
4. Run the Backtest
Once your strategy logic is defined either via code or the visual builder, you are ready to run the backtest. Within the Strategy Tester, specify the historical timeframe you want to run the backtest over.
Hit the “play” button and TradingView will walk through the historical data tick-by-tick, executing simulated trades according to the strategy rules you defined.
Tip: Start with a 1-year backtest, then expand to 5-years, 10-years etc to see how performance holds up over long periods.
5. Analyze the Results
Once the backtest completes, the key step is analyzing the results. TradingView provides extensive analytics to evaluate strategy performance:
Thoroughly analyzing results from different angles is crucial to gauging strategy validity.
6. Refine and Re-test the Strategy
Strategy development is an iterative process. Use the results and analytics from backtesting to identify areas for improvement.
Common refinement techniques include:
After making refinements, re-run the backtest and analyze to confirm the improvements. Repeat this process until you arrive at a strategy with satisfactory simulated historical performance.

7. Forward Test and Implement
The final step is walking forward with additional testing before going live:
Proper implementation combines backtesting, forward testing, paper trading, and prudent risk management.
Backtesting Best Practices
While backtesting on TradingView is relatively straightforward, adhering to sound backtesting practices ensures more accurate, reliable results:
Following sound backtesting methodology helps avoid issues like curve fitting that result in unreliable backtest results.
TradingView Backtesting Upgrades
While TradingView's free plan provides sufficient tools for basic backtesting, traders can unlock more advanced functionality with paid subscriptions:
Upgrading to a paid TradingView plan starting at $15/month provides a major boost in backtesting and strategy development capabilities.
Common Backtesting Mistakes
While backtesting can evaluate trading strategies, it's important to avoid some common mistakes that can derail the process:
Being aware of these pitfalls and adhering to sound backtesting methodology is key to avoiding developing strategies that look great on paper but fail in live trading.
FAQs on Backtesting with TradingView
Here are answers to some frequently asked questions about backtesting on TradingView:
How much historical data do I need for effective backtesting?
Aim for at least 5-10 years of historical data with at least 100 trades. The more data you can backtest on, the more reliable the results.
What is the best script for backtesting strategies?
Pine Script is the main coding language used for developing and backtesting custom strategies on TradingView. For no-code options, the visual Strategy Builder is beginner-friendly.
Can I automate my strategy to trade automatically?
Yes, with a TradingView paid plan you can connect your strategy to a brokerage account to automate live trading based on your backtested strategy.
What mistakes cause inaccurate backtest results?
Common mistakes include overfitting, curve-fitting, not accounting for slippage, avoiding robust statistical analysis, and testing with insufficient history.
Can I estimate future returns via Monte Carlo simulation?
TradingView paid plans allow Monte Carlo simulations which run thousands of randomized trials to estimate the distribution of returns from a strategy.
Is it better to code a strategy or use the visual builder?
Coding with Pine Script allows full customization but has a learning curve. The visual builder is quicker and simpler but more limited in functionality.
What other metrics beyond net profit should I analyze?
Robust backtesting looks beyond just profits to evaluate risk metrics like sharpe ratio, drawdowns, percent profitable trades, position sizing etc.
How can I simulate real-world imperfect order fills?
Use the strategy properties to add realistic assumptions for slippage and commissions to better reflect likely real-world performance.
What timeframe chart is best for developing strategies?
Shorter timeframes like 5-minute and 15-minute charts are best for designing intraday strategies. Use daily, weekly or monthly for swing or positional strategies.
Is backtesting enough or should I also paper trade?
It's recommended to paper trade in real-time in addition to backtesting to simulate actual live market conditions before risking capital.
