Backtesting: An Introduction
Before we define 'backtesting', it will be helpful to discuss the history of backtesting first. In 1980, a Forex backtest was a pretty straightforward concept. Traders would make their conscientious trades on charts, making the position either to 'buy' or 'sell'. Then, they would manually write exhaustive notes of their trade results in a log. Most of the trade ideas came from a profound understanding of fundamental analysis, or the awareness of market patterns. In the 1990s, a person was considered an 'investing innovator' if they were able to display data on a computer monitor.
The electronic process that allows us to check results online and gain confidence in our strategy today used to take months, even years, in the past. However, technological advancements have simplified the entire process for us. Being a forex back tester is now much easier.
Since then, the process has continued to advance, but not always for the better. Those who apply diligence and common sense to backtesting trading strategies in Forex are usually in a better position to be rewarded with tremendous gains.
On the other hand, traders who only apply computing power and leave human logic out of the picture are likely to suffer huge losses. When it comes to backtesting Forex strategies, no software can replace a human being – especially one equipped with the right tools.
Forex Back Tester Definition
Forex backtesting is a trading strategy that is based on historical data, where traders use past data to see how a strategy would have performed. The definition of a backtesting application is a set of technical rules applied to a set of historical price data, and the subsequent analysis of the returns that a Forex strategy would have generated over a specific period of time.
Backtesting Forex Strategies: Reasons to Start
Backtesting has a range of benefits for Forex traders, including:
- Strategic insight: The main benefit of Forex backtesting is that traders can determine whether their chosen strategies will deliver their expected returns.
- Practice: Backtesting can help traders spot trading opportunities by looking at past price movements and recurring patterns. In other words, it helps traders develop their technical analysis skills.
- Confidence: Backtesting Forex is a good way to build confidence, as traders gain experience by testing traders on past price information. This helps build their confidence for when they start trading 'for real'.
Ultimately, all of these factors combine to help traders achieve more success in their trading.
So, how can you backtest? This is where Forex backtesting software comes into play.

Forex Backtesting: What is it and How Does it Work?
Forex trading strategies are applied to a set of price data, and trades are reconstructed using that data. This data can be used by traders to ascertain any unforeseen flaws in their current strategies. Alternatively, new strategies can also be tested before using them in the live markets.
Depending on the type of backtesting software used in Forex trading, traders can get a wide range of indicators, such as:
- Total Return on Equity (ROE): Returns, expressed in terms of percentage of the total equity invested.
- Total Profit and Loss (P/L): Total profits and losses generated by a strategy, expressed as a percentage of the invested equity.
- Total Gain/Loss Ratio: The ratio of how many trades resulted in gains, and how many in losses.
- Annualised ROE: The total return likely to be generated by a Forex strategy over the entire calendar year.
- Volatility: What kind of market conditions were your strategies working in, uptrends, and downtrends.
- Risk-Adjusted Returns: Calculating your returns in relation to the risks involved within a strategy.
All these metrics provide you with insights into how your Forex trading strategies are performing.
Forex Backtesting Strategies: Factors Influencing Results
The best backtesting software in Forex depends on certain variables that can affect the outcome of the entire process. You should be aware of the following three factors that can alter the results of trading strategies:
- Data Quality and Source: The accuracy and reliability of price data is important in backtesting. It also has to be relative to your strategy. Remember that not all data is created equal in the OTC (over-the-counter) markets. Online Forex brokers and banks have different price data at the same point of time.
- Determinism: How will the results vary when the same strategy is applied on a data set several times? Backtesting strategies should be 100% deterministic. You should get similar results every time you backtest a Forex strategy for a defined data set. While this might be the ideal scenario, it doesn't always occur.
- Logic of Trade Execution: How logical and realistic is the trade logic that is embedded in the backtester? Backtests are never the perfect representation of the real markets. You will be missing important factors like slippage, latency, rejections or even re-quotes.
It is also important to consider whether you are using bar data or tick data. Tick data can allow near-perfect historic simulation of your data. This process is slower when including bar data. With bar data, for each time interval, you receive 4 price points. The longer the time-frame, the more accurate the results will be.
Please note that even the best backtesting software cannot guarantee future profits. Infrequent liquidity is a frequent issue in the Forex markets. It is governed by various external factors and is very difficult to simulate.
How to Backtest a Forex Trading Strategy
There is a range of backtesting software available in the market today. Each Forex strategy tester has its own way of evaluating Forex trading strategies. Forex backtesting can be broadly divided into two categories – manual and automated.
Traders also have the ability to trade risk-free with a demo trading account. This means that traders can avoid putting their capital at risk, and they can choose when they wish to move to the live markets.
Backtesting Forex Strategies Manually
Being a manual Forex back tester involves a fair amount of work, but it is possible. In manual Forex backtesting, you just take the historical data and step through it. A charting tool will help you to go bar by bar so that you can observe the price action and subsequent performance metrics along the way. The advantages of manual backtesting include:
- The fact that it can be performed by anyone.
- That as you execute every trade, you will develop an understanding of how your Forex trading software works. You will know what can be improved and you can even develop an automated strategy later on.
- Manual back-testing simulates live trading mechanisms, such as entering or exiting a trade, risk management, etc.
Manual backtesting methods can be a good way to start before you proceed to use automated software. Using an excel spreadsheet for backtesting Forex strategies is a common method in this type of backtesting.
Backtesting Forex Strategies Using Excel
Many traders believe that one shouldn't have to be a programmer or an engineer to backtest a strategy. This method takes us back to the very basics, which anyone can use. Spreadsheet programmes such as Excel are among the best ways to backtest Forex trading strategies for free.
You need a publicly available source of data, such as 'date/time', 'open', 'high', 'low', 'close' or 'prices'. The time component is essential if you are testing intraday Forex strategies. To get the data, you can simply go to Yahoo Finance or Google Finance.
In the field "Enter Symbol/Company Name," fill in the symbol for the currency you want to see the data for. In the "Quotes" field, you will find the option to get historical prices for the symbol. Enter the date range here. Scroll down to the end of the page and click "Download to Spreadsheet".
Use the "Sort" option in Excel's data menu to prepare the data. Here's a look at one way to find the day of the week that provided the best returns. Suppose, our strategy is "buy the open" and "sell the close."
- Column A - Date Column
- Column B - Open Price
- Column C - Close Price
Now comes the tricky aspect of using the formula that will provide the best results:
- In Column D, we use this formula: = IF(WEEKDAY($A2,2)=D$1,$C2-$B2,""). This formula has to be copied across all columns from D to H.
- ($C2-$B2) – Close Price minus Open price; the true part of the statement that gives us the profit/loss.
- (") – The False part of the statement, in the form of double quotes, which doesn't give any result if the day of the week is unmatched.
What the formula means is that if the day of the week (converted to a number between 1 to 5, which matches Monday to Friday) is the same as the days of the week in the first row of this column (D$1) then you will see the result accordingly. You can also choose to include average and sum functions at the bottom of the "Weekday" column to find the most profitable day to implement this strategy over the long term.
This is a strategy for backtesting using the manual option. You can use many expressions and conditional formulae like this for testing Forex strategies. However, this method is tedious and time-consuming. One software that would be ideal for manual backtesting would be TradingView.
Backtesting on TradingView
Launched in 2011, the TradingView platform is a good option for free Forex backtesting software. This Forex trader software is best known for its advanced charting tools. Real-time data and browser-based charts make research from anywhere possible, since there is nothing to install, and no complex setups to be taken care of.
It is a social platform, where you can even share, watch or collaborate with other traders and publish your strategies on social media profiles like Twitter or blogs. One of the most useful tools for backtesting on this platform is the Bar Replay Feature.
To use it, follow these steps:
- Turn on Bar Replay: Use the icon on the toolbar at the top of the screen.
- Adjust Settings: A new toolbar will appear on your active chart, and a vertical red line will appear where the cursor is. This red line marks the area where the replay begins. Scroll back to the point from where you want it to start.
- Click the Play Button: Click on the chart once to get into replay mode; then click on the play button so that the replay can start.
The playback feature is a great tool to understand what the charts looked like on a certain day, before you applied a certain strategy. However, the currency pairs that you test need to have enough historical data available for them. There are certain limitations of TradingView that you should also be aware of, such as:
- The fact that there is no option to use Japanese Candlestick Charts
- The fact that the 'Continuous Futures' chart doesn't work with 'Bar Replay'
- There is limited historical data on some chart options
- Demo orders cannot be created in this mode

Automated Forex Backtesting Strategies
Automated backtesting involves the creation of programmes that can automatically enter and exit trades on your behalf. These programmes can be obtained free of cost online, although premium versions are available for purchase as well. One of the primary advantages of these tools is that they remove emotions from your trading activities. Many traders often use these tools on copy trading strategies to enhance the chances of success.
However, keep note that your programme has to match up to your personality and risk profile. Also, not all trading methods can be used with automated strategies.
Both MetaTrader 4 (MT4) and MetaTrader 5 (MT5) offer automated backtesting tools. Both MT4 and MT5 are proven and secure electronic trading platforms; popular choices for trading the financial markets.
The indicator-rich MetaTrader 4 Supreme Edition plugin is the preferred option, owing to the additional features included that enhance the trader's experience. MetaTrader 4 is popular for FX backtesting because of its in-built 'Strategy Tester' feature.

Institutional Grade Backtesting Software
Proprietary trading houses, hedge funds and family businesses often use institutional backtesting software. Such software is available for use only after the license to do so has been purchased by the user.
Although considered expensive, they do offer a complete solution package for data collection, historical backtesting, Forex strategy testing and live execution of high-frequency level strategies across various instruments. Since such systems are event-driven, the backtesting environment they provide can simulate live trading environments with higher accuracy. Here are some examples:
7 Tips When Using Automated Backtesting Strategies
- Learn the exact parameters of the trading system, so that you know when it would stop
- You will still need to check the system regularly, even though it is automated, in case the market conditions have changed
- It is suitable for longer time periods, only if it suits your risk tolerance levels
- There are no guarantees that your backtesting method will work in live trading. Like manual strategies, they too have to be forward tested
- You have to understand a fair bit about coding. One misplaced punctuation in the code and your strategy can backfire
- Automated backtesting methods do not work well for all trading plans
- Curve fitting methods often fail in live trading environments
Whichever strategy you choose, analysis of your strategies will require competent Excel skills. Of course, sharpening up your general Forex trading knowledge and strategy skills is also important.
