Lesson 7 of 9

Already an Interactive Brokers Client?

New to Interactive Brokers?

Discover a powerful options research tool available free within Trader Workstation (TWS). 

Options traders often spend significant time searching for strategies, evaluating risk, and wondering how a trade idea might have performed in different market environments. What if much of that research had already been done? 

Interactive Brokers clients have access to the ORATS Backtester directly within Trader Workstation (TWS), providing a vast library of pre-calculated options strategy backtests covering popular stocks, ETFs, and indexes. The tool allows traders to review historical performance, compare strategies, and evaluate risk characteristics before committing capital. [interactiv…rokers.com][orats.com] 

Whether you’re evaluating covered calls, credit spreads, short puts, iron condors, or other common options strategies, ORATS can help you move beyond assumptions and begin your research with historical data. 

What Is ORATS? 

ORATS (Option Research & Technology Services) provides options research tools, data, and analytics used by professional and retail traders alike. Within TWS, the ORATS Backtester gives IBKR clients access to a large collection of historical options strategy tests that can be searched, filtered, and analyzed directly from the platform. [interactiv…rokers.com][interactiv…rokers.com] 

The backtester includes: 

  • Historical tests for common options strategies 
  • Coverage of actively traded equities, ETFs, and indexes 
  • Performance metrics and risk statistics 
  • Historical equity curves 
  • Monthly return analysis 
  • Detailed trade logs 
  • Powerful filtering and ranking tools [interactiv…rokers.com][orats.com] 

The goal is simple: help traders evaluate how a particular strategy has historically performed under specific conditions. 

Why Backtesting Matters 

Imagine you are bullish on a stock and are considering several approaches: 

  • Buying a call option 
  • Selling a cash-secured put 
  • Establishing a bull put spread 
  • Writing a covered call 

Which approach has historically offered the best balance between return and risk? 

Without historical analysis, traders often rely on intuition, anecdotal evidence, or recent market experience. Backtesting provides another perspective by showing how similar strategies performed over many years and through different market conditions. 

While historical performance never guarantees future results, reviewing long-term data can help traders: 

  • Understand potential risk and reward 
  • Identify periods of strong or weak performance 
  • Compare multiple strategies objectively 
  • Evaluate drawdowns and consistency 
  • Develop greater confidence in their decision-making process 

In other words, backtesting turns a trading idea into a research project. 

Getting Started with ORATS in TWS 

Finding the tool is straightforward.

New users should spend a few minutes reviewing this page before exploring the more advanced sections. 

Step 3: Explore Featured Backtests 

For many traders, the Featured Backtests section is the ideal starting point.

  • Underlying symbol

  • Historical performance measures 

Selecting a strategy opens a detailed analysis window where traders can study the results in greater depth. [interactiv…rokers.com] 

The Real Value of ORATS 

Many traders assume they must build complicated spreadsheets or write custom code to evaluate options strategies. 

ORATS takes a different approach. 

The platform gives traders access to a large collection of historical research that can be searched and filtered in minutes. Rather than starting with a blank screen, users can begin with strategies that have already been analyzed across years of historical market data. [orats.com][interactiv…rokers.com] 

This can be particularly valuable when exploring: 

  • Covered call opportunities 
  • Cash-secured put strategies 
  • Vertical spreads 
  • Iron condors 
  • Calendar spreads 
  • Other income and directional options strategies [orats.com] 

A Practical Next Step 

Suppose you’re interested in trading Apple (AAPL). 

Rather than immediately placing a trade, you could use ORATS to: 

  • Search for historical AAPL strategy results 
  • Compare covered calls versus short puts 
  • Evaluate risk-adjusted returns 
  • Review drawdowns 
  • Examine how different strike selections and expiration cycles affected outcomes 

This approach allows traders to begin their analysis with data rather than speculation. 

In the next article in this series, we’ll walk through a practical example using Apple (AAPL) and show how ORATS can help traders compare multiple options strategies on a single underlying before making a trading decision. 

Key Takeaway 

The ORATS Backtester is one of the most powerful yet underutilized research tools available within TWS. By providing access to a vast database of historical options strategy tests and detailed performance analytics, it allows traders to spend less time guessing and more time evaluating ideas based on evidence. Before your next options trade, consider starting with a backtest. The research may already be waiting for you.
