Backtesting Options Strategies: How to Do It and Which Tools to Use

Backtesting is a critical component of successful options trading because it lets traders test out strategies without putting any of their money at risk! As a result, traders who backtest their strategy can move forward with the utmost confidence due to these data-driven insights. Options traders can test options using alternative timelines or out-of-sample data to confirm any strategy’s effectiveness.

A key element of backtesting is reviewing historical data before committing real money—it ultimately reduces your overall risk and improves strategy effectiveness. Our backtesting guide will walk you through the process of backtesting options strategies, show you the best practices for developing a solid backtesting routine, and show you which are the most valuable tools for getting the job done!

What Is Backtesting?

Backtesting is when traders test trading strategies without risking capital. The role of backtesting involves evaluating the historical performance of a trading strategy using past market data. Traders can apply their strategy or a predictive model to determine the strategy’s accuracy. Backtesting strategies can be measured using metrics like return, profit/loss, market exposure, risk-adjusted return, or volatility.

Why It’s Important for Options Trading

Options pricing is complex due to its intrinsic value and because it is affected by multiple variables. Factors like implied volatility, interest rates, time to expiration, supply and demand in the market, underlying asset price movement, and dividends determine option pricing.

Backtesting can improve your overall trading decisions by providing the following insights:

• Parameter Optimization: Use historical data in your backtesting process to define entry and exit points and other important parameters for your personal strategy.
• Adaptability: Backtesting can help you find the best strategies for the current market conditions.
• Confidence Booster: Gain confidence in your trades and investments by viewing past performances that have worked for you.
• Mitigate Risk: Use backtesting to minimize potential losses and maximize profits by avoiding common pitfalls associated with flimsy strategies.
• Evaluate Your Performance: Backtesting can reveal how specific strategies will endure certain market conditions. Find out if your trades or investments will hold up in bull or bear markets.
• Get Around Psychological Biases: Traders who backtest can rely on data to guide them and avoid falling into the trap of psychological biases, which can lead to mistakes in options trading.

Because of all the moving parts involved in online trading options, traders need access to tools that let them test their strategies without risking money or being subject to time restrictions.

Understanding Expectations vs. Reality

Backtesting helps traders align expectations with potential real-world outcomes, helping to weed out poor strategies and refine promising ones. Traders can discover viable strategies to be applied and executed in the real market. As we discussed previously, traders are relying on historical data and proven strategies they discover during the backtesting process, which can lead to better decision-making and reduce mental stress.

Steps to Backtest an Options Trading Strategy

Informed decisions in an environment where things can be highly uncertain are your key to successful options trades. And how do you navigate the ups and downs of the online trading world to come out ahead?  The power lies in being able to backtest trading strategies so that you aren’t putting any of your capital at risk.

How do you develop a sound backtesting rhythm to see whether specific strategies are worthwhile? Keep reading to discover how you test your new options trading strategy. You must complete some general steps to make quality backtesting a reality in your online trading routine.

Define Your Strategy

First, you must set the rules and criteria to govern and inform your trading strategy. It’s the framework of your potential strategy where all the critical parameters are established, including factors like risk management, position sizing, and entry/exit conditions.

Set Parameters

Defining your strategy involves setting up key parameters like strike prices, expirations, delta, gamma, or volatility conditions. By testing these key elements, you can discover the sweet spot for performance when you compare each strategy against historical data.

• Capital: This takes into account the amount of capital at risk, initial capital, and overall portfolio size. Initial capital refers to the maximum capital allocated to a trader for each instrument. It’s hypothetical capital that the trader might not hold.
• Fees: Brokers charge commissions for executing trades, and traders should incorporate these transaction costs into their backtesting routine.
• Strike Price: The price the security’s seller fixed after receiving bids in a tender offer. It’s typically for selling bonds or a new stock market issue. Factors affecting strike price include risk tolerance, time decay, volume or liquidity, risk-reward payoff, bid-ask spread, and implied volatility.
• Expirations: These are the times and dates when an options contract becomes invalid and no longer has any value. Expirations can affect the option’s value and ultimately dictate the strategy investors or traders can use.
• Volatility Conditions: These metrics help traders evaluate a trading strategy’s risk and performance. They provide insights into the asset’s overall volatility and the applied strategy’s equity curve.
• Bid-Ask Spread: This refers to the difference between the asking price and the bidding price of a security or other assets: the difference between the highest price a buyer will offer and the lowest price a seller will accept.

Trading Rules

Lay out the entry and exit rules clearly. When are you buying or selling options? Under what conditions do you take profits or cut losses? If you’re unfamiliar with entry or exit rules, continue reading, and we’ll shed some light on how these parameters work for options traders from all sorts of backgrounds.

Entry Rules

• Market Sell Orders: You will get the best bid price by entering one of these orders. You can spread the number of contracts over a single trading day. If the quantity you purchase is less than your order size, you can sell the number of contracts available at that price and the rest at the next-best price.
• Limit Orders: If you’re concerned about the price you’ll get when entering any given market order, this order requires you to specify the lowest price you’re willing to accept.
• Options Strategies: When you buy a call option, you anticipate the stock price will increase while selling a put option means that you anticipate the stock price will either stay stable or decrease.

Exit Rules

• Profit Target: Traders can set up exit points based on a specific profit target, ensuring that they leave positions when they’ve made the profit margin they were set on.
• Letting an Option Expire: In some markets where volatility is commonplace, and the underlying asset’s price might fluctuate significantly at any given time, traders will let an option expire so that the maximum loss is the premium paid on the option.
• Loss Tolerance: Traders can plan exit points based on how comfortable they are with losing. An example of this would be a trader exiting a position based on a predetermined loss tolerance parameter of 10%. The trader would close out a position when they can repurchase it for 10% of the initial premium.
• Time Exit Strategy: Traders can exit positions when they have held them for a specific amount of time. If the prices are moving against you but aren’t enough for a stop-loss order to kick in, the time exit strategy lets you exit that position quickly compared to other methods.

Choose a Time Frame

Another important element in backtesting your trading strategy is choosing the proper time frame. Your time frame should coincide with factors like your personal trading strategy, the market you’re trading in, slippage, and historical data.

Time Period Selection

Another vital step in backtesting any strategy you’d like to use in options trading is selecting a time frame and considering the need for diverse market conditions. Consider the factors you might consider when choosing an appropriate timeframe for backtesting your strategy.

• Trading Strategy: Some people are day traders or practice scalping (short-term trades) or swing or position traders (long-term trades), so it’s important to choose a time period that fits the type of trading you engage in. If you’re backtesting a strategy for a trading strategy that takes place over the course of a few hours, you might select time periods that go back several months. For longer-term trading strategies, you can backtest time periods as far back as six months to a year.
• Historical Data: To confirm your strategy’s potential, you can backtest them on historical data from different time periods.
• Market: When choosing a time frame for backtesting, you must consider current market conditions, such as a bear, bull, or sideways market. Diverse market conditions will ultimately inform the best time frame for backtesting your models and strategies.
• Slippages: Just as you can simulate strategies through backtesting to affirm the strategy’s effectiveness, you can also apply small slippages to your backtesting data to simulate real-world slippages that might occur when trading options for real.

Avoiding Data Bias

Using diverse time frames to avoid overfitting one specific market condition is vital in backtesting your trading strategy. You should generally avoid several types of data biases when developing strategies for your options trades and other online investments.

• Survivorship Bias: Historical data and delisted assets can provide an accurate gauge for potential losses. This is a key way to avoid data bias in backtesting and get an idea of real-world conditions via diversification across market caps and sectors.
• Data-Snooping Bias: This data bias occurs when traders cherry-pick information to suit how they envision their trades performing. It can also occur when they look at too many indicators or parameters when testing their strategy.
• Look-Ahead Bias: You can accidentally bias your results when you examine data or information that was unavailable when you made the trade. You can retroactively apply this data to a trade because it will yield inaccurate results.

Gather Historical Data

This is the backbone of backtesting your options traders. Historical data not only provides you a roadmap of what could work for your upcoming trades, but it can also deliver confidence to traders because you’re going off of information that has worked in the past for various asset classes, market conditions, or trade kinds.

Data Sources

Traders can obtain accurate historical options data from several different sources to inform their backtesting method. You essentially have three choices: broker apps, third-party providers, and financial APIs. Your choice for gathering historical data all depends on what you’re comfortable with in your backtesting process.

• Broker Platforms: Many broker apps have backtesting tools that allow traders to test multiple strategies without risking capital. Some examples of broker apps with backtesting software include Trading View, NinjaTraders, Amibroker, TradeStation, MetaStock, and many others.
• Third-Party Providers: If you don’t want to use a broker app to access backtesting tools, there are several third-party providers, such as OptionStrat, Option Omega, eDeltaPro, Option Alpha, and ORATS.
• Financial APIs: These are application programming interfaces, basically, software intermediaries that let different financial applications and systems communicate and exchange data. Some financial APIs available for backtesting are Alpha Advantage, Intrinio, Polygon, MARKETSTACK, and EOD Historical Data.

Types of Data Needed

When rounding up the data points you’d like to incorporate in future trades, there are certain boxes you’ll want to tick to ensure you’re using a robust backtesting strategy. These will include factors such as:

• Historical Prices: Looking back over the historical price records can indicate what has worked in the past. It is likely that it will work this time around. This information can help traders determine the profitability, feasibility, and risk involved with any strategy they test.
• Implied Volatility: By gathering this data for backtesting, traders can establish firm entry or exit positions, balance leverage, and reduce commission or execution costs. Because volatility is derived from option prices and future price fluctuations in the market, traders can effectively use it to determine the risks/rewards of each trade and gauge market sentiment.
• Volume: Gathering data on trade volume can identify market trends, momentum, breakouts, and selling or buying potential. It’s also helpful in gauging the strength of a move, pinpointing reversal days or exhaustion days, and can prove once and for all which technical indicators of patterns are working.
• Open Interest: This data is mainly used to refine current trading strategies based on historical performance. It is also used as an indicator to confirm trends or trend reversals in the options market.

Execute the Backtest

Let’s examine how a trader executes the backtest. There’s a heavy emphasis on simulating traders and tracking performance, so we’ll discuss the best software to automate the process, and the metrics traders should use, such as risk-adjusted returns, win rate, drawdowns, etc.

Simulate Trades

The first step in simulating trades in a backtesting program is to choose a trading platform, brokerage app, or a third-party backtesting site to get the job done. Then, you’ll want to follow these general steps to begin simulating the trade strategies you’re interested in using:

• Select the trading system you’d like to backtest
• Open the trading system
• Input your parameters
• Run the test
• Analyze the results
• Optimize your strategy by entering different parameters

In these backtesting sessions, you’ll want to use a defined strategy over the selected time period. You can choose between manually executing a backtest or using software to automate the process. Automated backtesting software includes platforms like TradingView, Trade Ideas, Amibroker, Forex Tester, and MetaTrader 5.

Tracking Performance

During backtesting, traders should track several metrics to gauge the performance of each position or instrument they’re currently interested in adding to their portfolio. These include the following:

• Win Rate: A crucial element of tracking the performance of your strategy is examining the win rate of any backtest by dividing the winning trades by the total trades. Possible high-win rate strategies can be found using technical analysis and various time frames.
• Average Profit/Loss: To discover the average profit for your strategy, divide the total profit by the number of trades. Use the same method when gauging average loss. The trade simulations that deliver the best average profit are the ones you might consider using once you’re done with your backtests.
• Drawdowns: This is the percentage decline in the value of a reading account. Measuring the peak of a trading account to its lowest point can give insights into the most significant decreases of any given options trading strategy and offer traders an excellent idea of risk exposure.
• Risk-Adjusted Returns: This method for tracking performance measures the return on investment while considering the risk involved in producing the return. It can help investors or options traders determine if their return is worth the level of risk taken, and they can make accurate comparisons between trades with different risk levels.

Analyze the Results

Now comes the time in the backtesting process when traders must evaluate each outcome. Depending on how things pan out, there might be a time for strategy adjustment or retesting under different conditions or circumstances.

Evaluating Outcomes

When reading and assessing your backtest results on options trade strategies, you’ll want to compare them against expectations and identify potential weaknesses in the overall strategy. A good rule of thumb in evaluating backtest outcomes is to consider these factors:

• Only evaluate strategies that have made money
• Check the primary performance indicators like rate of return, max drawdown, win ratio, and payoff ratio
• Take all trading costs into consideration
• Use a sample size of 30 or more traders before evaluating
• Confirm your model’s performance was carried out by overfitting by using data that wasn’t used to develop the model (out-of-sample tests)
• Employ forward performance testing
• Find out how sensitive your model and strategy might be by varying the parameters

Adjust and Retest

We briefly touched on the iterative process above and the idea of adjusting the strategy based on the findings. Varying the parameters and then retesting under different conditions is the key to discovering how sensitive your current trading strategy or pricing model might be to risk. Adjustments and retesting can help fine-tune a strategy with great potential!

Best Practices for Backtesting Options Strategies

There are right and wrong ways to backtest options strategies, and we’ll be discussing the best practices for performing effective backtests on all your options strategies in this next section. The more traders can get into these rhythms when backtesting various methods, the quicker they can discover what works and weed out what isn’t worth the time or effort.

Use Sufficient Data

Getting sufficient data to inform the backtest is a balancing act. Not only is it critical to use the correct data, but it’s also important to strike a balance on the data you’re using. You can get into the bad habit of including too much data, which can lead to overthinking the effectiveness of your trade strategy or cherry-picking data points that prove the model’s effectiveness and ignoring other metrics that could reveal weaknesses in the plan.

Avoiding Overfitting

Overfitting occurs when your model fits the historical data too well. It happens often with traders who cherry-pick data to show that their model is effective, but it doesn’t generalize to new or unseen markets. Overfitting usually results in disappointing real-life trade outcomes because the backtest results are sometimes inflated or unrealistic.

There are a few ways you can avoid overfitting during your backtests:

• Take advantage of statistics and performance metrics
• Use out-of-sample testing
• Use cross-validation
• Include robust data
• Use realistic assumptions
• Simple models are the key (don’t overcomplicate)
• Use your common sense and best judgment

Over optimizing a strategy to fit past data perfectly is risky because your real-life traders could endure poor performance in live markets. In addition to the methods for avoiding overfitting above, we recommend testing across different market environments with high and low volatility rates.

Incorporate Transaction Costs

Keeping a detailed list of transaction costs is an important element to consider when running backtests to ensure you can execute profitable trades. You must understand your broker’s fee structure to convert those fees to basis points and consider the wider bid/ask spreads with non-liquid options with thinly traded derivatives.

Fees and Slippage

Transaction costs like commissions, fees, and slippage must be considered when backtesting. There are explicit and implicit costs—explicit costs include commissions, taxes, and exchange fees, while implicit costs involve indirect factors like the impact of the trade on the received price. They can significantly impact the performance of an options strategy. You typically experience lower negotiated feeds with larger funds with a higher trading volume.

Factor in Real-World Constraints

Real-world constraints are often overlooked in backtests, but they can provide critical insights into each strategy’s performance—a step you won’t want to skip when running option trading strategies through their paces.

Liquidity and Execution

Taking these factors into consideration can give you a great idea of the accurate real-world performance of your options trading strategies:

Liquidity is the availability and demand of buyers and sellers in the market. It can affect the speed at which traders’ orders are executed, and it can also affect fees or slippage incurred during this time. If orders are routed to different exchanges based on liquidity access, your backtest’s performance can vary wildly from the real-life performance. It’s essential to incorporate liquidity into any model you’re running.

Equally important is considering margin requirements. You must evaluate the adequacy of margin cover for the required money needed to account for market risk. Traders must look at their portfolios’ profits and losses and compare those against margin requirements. When it comes to execution delays, many traders will incorporate slippage into their models to account for real-world market slippage.

Avoid the Hindsight Bias

Hindsight bias occurs when traders look back on unpredictable events and think they were much more predictable than they were at the time. The thing about hindsight bias that can hurt traders is that this overconfidence can lead some to take unnecessary risks. If you look at all your past trades as easily predicted, you can overestimate your ability to foresee the consequences of your trading decisions.

Objectivity in Strategy Testing

It’s important to retain objectivity when testing new options trading strategies. Much of avoiding the hindsight bias is keeping a journal of all your trades and how you felt before and after each. This can keep things in perspective for you, and you don’t unintentionally adjust strategies to “fit” past events of which you already know the outcomes. One of our top recommendations in backtesting would be to trade the strategy forward using paper trading. You’ll want to do this after backtesting to validate the results.

Popular Tools for Backtesting Options Strategies

There are three primary ways that traders can run backtests on their options strategies: broker apps with backtesting capabilities, dedicated backtesting software, and web-based backtesting tools.

The Limitations of Backtesting

While backtesting can lead to increased profits and greater peace of mind, it has some significant limitations. These include overfitting a strategy, data discrepancies, transaction costs, and human psychology. We’ll discuss these in more detail as we discuss where backtesting can fall short for traders and investors.

Just because a strategy worked in the past doesn’t mean it will work in the future. Past performances don’t guarantee future results. Backtesting is a valuable tool and guide for maximizing profits, but it doesn’t ensure a profit. Because regulations, investor sentiment, and market conditions are subject to change, past performance can sometimes become irrelevant.

Unforeseen Market Events

Backtesting doesn’t account for black swan events or significant market shifts that can disrupt even well-tested strategies. Black swans are unexpected or rare events that are difficult to predict and can significantly impact. Backtesting is rendered useless in many cases when events like this occur because the regular playbook gets thrown out the window during unexpected times like these.

Backtest Your Strategies with Caution and Realism

Backtesting is key to creating an effective options trading strategy and pinpointing moves to increase your portfolio performance. A few of the perks that come from backtesting strategies include:

• Identifying strengths and weaknesses within the strategy
• Building confidence in a trading plan
• Testing the viability of a strategy
• Analyzing the risk and profitability of a plan
• Allowing traders to stick with a trading strategy

One advantage of backtesting is that traders and investors can experiment with different settings, tools, and strategies. We’d encourage experimentation in backtesting but also caution and realism in approaching it. Backtesting is a powerful tool, but it should be paired with forward testing and real-world validation. Try some of the tools we mentioned to refine your approach to backtesting and develop a solid system for testing your trade strategy. Feel free to share your experiences with backtesting options strategies. We’d love to hear your feedback and thoughts on the matter.
