TradingView has become one of the most popular trading platforms for technical analysis and charting. Its online charting software is free to use and packed with powerful features for analyzing financial markets.
One of TradingView’s most advanced capabilities is its backtesting tool. Backtesting allows you to test automated trading strategies on historical data to see how they would have performed.
But is TradingView’s backtesting feature a viable option for rigorously testing your trading strategies? In this comprehensive review, we’ll take an in-depth look at TradingView backtesting to see if it’s an ideal solution for strategy testing and development.
Overview of TradingView Backtesting
TradingView’s backtesting feature allows you to test trading strategies on historical price data to gauge their hypothetical performance. You can backtest stock trading strategies, forex strategies, crypto strategies and more.
Some key things to know about TradingView backtesting:
- Programming Required – You need to know Pine Script, TradingView’s proprietary coding language, to program your strategies.
- Customizable – You can fully customize strategies with indicators, conditions, orders types, etc.
- Flexible Timeframes – Backtest across minute, hourly, daily or weekly timeframes on the timeframe of your choice.
- Detailed Statistics – TradingView provides extensive backtesting statistics to evaluate performance.
- Cloud Processing – Strategies are run on TradingView’s cloud servers for faster backtesting.
- Visual Replay – Watch a visual replay of your backtest on the chart.
- Strategy Sharing – You can publish strategies for others to see, test, and automate.
Key Benefits of TradingView Backtesting
TradingView backtesting provides several advantages for testing and developing trading systems:
1. Easy to Use Interface
The backtesting interface is integrated directly into TradingView’s charting application. This makes it easy to quickly backtest ideas without having to export data or learn another platform.
Settings like strategy logic, initial capital, commissions, slippage etc. can all be configured through their simple UI.
2. Cloud Processing Speed
Since backtests are run on TradingView’s cloud servers, you can get results much faster than local backtesting software. Strategies can be run on multiple historic years in just seconds or minutes.
This allows you to quickly iterate on strategy ideas without waiting hours or days for a backtest.
3. Detailed Performance Metrics
TradingView provides in-depth statistics on key performance metrics:
- Profitability – Gross profit, gross loss, profit factor, expectancy
- Risk – Max drawdown, Sharpe Ratio, sortino ratio, calmar ratio
- Efficiency – Return on equity, return on investment
- Trade Activity – Number of trades, percent profitable, average trade
The metrics give you quantitative insights into a strategy’s hypothetical viability.
4. Visual Replay on Charts
One big advantage TradingView has over standalone backtesting software is the ability to visually replay your full backtest on the chart.
You can watch each entry and exit play out on historical data to better understand the strategy’s actions. This helps quickly identify flaws or areas for improvement.
5. Easy Strategy Sharing
You can publish backtested strategies on TradingView’s platform for free. Other traders can then easily test your strategies and provide feedback.
Sharing also allows you to automate strategies by connecting TradingView to brokers that support automated trading. Published strategies can be turned into bots.
6. Integrated Strategy Development
Having backtesting directly in the TradingView environment leads to an integrated workflow for developing strategies.
You can seamlessly switch between building/coding a strategy in Pine Script, backtesting it, then analyzing it on the charts – all within the same platform.
This helps accelerate strategy R&D versus using separate tools.
Limitations of TradingView Backtesting
While TradingView backtesting offers many benefits, it does have some limitations:
Limited History for Cryptocurrencies
TradingView has abundant historical tick data for stocks and forex currencies often going back decades. However, for cryptocurrencies, the historical data is more limited.
For some crypto pairs, TradingView may only have daily data going back a few years. This makes robust backtesting more difficult for crypto strategies.
Assumptions of Perfect Orders
TradingView backtesting currently assumes all orders are filled perfectly at the exact requested price and timestamp. This does not account for potential slippage and gaps you would experience in live markets.
So performance results may be inflated compared to real-world trading where orders can slip or fail to fill. More sophisticated order execution logic is needed.
Coding Required
You must learn TradingView’s Pine Script language to code strategies which has a learning curve. It’s less accessible to traders without programming experience compared to visual strategy builders.
This can limit the pool of traders able to utilize TradingView backtesting and share strategies.
Limited Optimization
While you can optimize parameters in TradingView, the optimization methods are basic and local optimizers. More advanced global optimization and machine learning techniques cannot be applied.
No Portfolio-Level Backtesting
TradingView currently only allows backtesting one strategy/system at a time. You cannot backtest a whole portfolio of multiple systems to analyze correlations, drawdowns, risk management etc.
This limits its usefulness for fund-level strategy analysis. You would need additional software to backtest multiple strategies simultaneously.
Costs for Live Trading
To connect TradingView strategies to live brokers for automated trading costs upwards of $15/month for the API connection. This recurring fee eats into profitability when going live.
The platform is less amenable to very low cost, high frequency trading. Costs add up quickly as you scale strategies.
TradingView Backtesting vs Alternative Platforms
TradingView is far from the only platform that provides backtesting functionality. How does it compare to popular alternatives for more advanced users?
Below we compare TradingView to MetaTrader 4, QuantConnect, and Deltix for professional-level backtesting:
Feature | TradingView | MetaTrader 4 | QuantConnect | Deltix |
---|---|---|---|---|
Software Type | Browser-based | Desktop | Cloud | Desktop/Cloud |
Language(s) | Pine Script | MQL4/MQL5 | C#, Python, F# | Python, C++, C#, Java |
Ease of Use | High | Moderate | Moderate | Low |
Backtest Speed | Very Fast | Moderate | Very Fast | Very Fast |
Customization | High | High | Very High | Very High |
Strategy Optimization | Basic | Moderate | High | Very High |
Tick Resolution | Tick, Min, Hour, Day | Tick, Min, Hour, Day | Tick, Second | Tick, Nanosecond |
Machine Learning Capabilities | None | None | Extensive | Extensive |
Portfolio Backtesting | No | Yes | Yes | Yes |
Cost | Free platform $15+/month deployment | Free | $99/month Fee discounts over $100k | >$4,000/yr |
As we can see, TradingView provides the easiest user experience given its web interface and visual backtesting. It also leverages cloud servers for very fast backtesting speeds.
However, platforms like QuantConnect and Deltix offer features more tailored for advanced users andinstitutions. This includes highly-customizable backtesting, optimization methods, ultra high-resolution data, machine learning, and portfolio-level analysis.
So while TradingView meets the needs of many retail traders, institutions may prefer more heavy duty platforms with additional capabilities and support.
