Tools and Data Challenges in Options Strategy Backtesting
Summary
The discussion surveys software and methods for testing options strategies, including multi-leg spreads. It explains why this work is harder than testing linear instruments: historical option chains are large, implied volatility histories may be unavailable, and accurate simulations require assumptions about option prices and strategy adjustments. Replies name commercial platforms, broker tools, open-source libraries, and historical data services, but most recommendations are time-sensitive and are not independently evaluated.
A low-cost approximation is to derive option prices from a model such as Black–Scholes using historical volatility or implied volatility as a proxy. The document cautions that results from such home-built tests can be misleading because their assumptions may diverge from actual market prices and trading conditions. It also mentions methodology papers and rule-based tools for automating entries and adjustments. The thread provides examples of available approaches rather than a controlled comparison of tool quality, pricing, data coverage, or realistic execution assumptions.
Key ideas
- Options backtests require historical option data and careful handling of multi-leg positions and adjustments.
- Historical implied volatility data can be difficult to obtain, limiting realistic price reconstruction.
- Black–Scholes prices with historical volatility offer a simple approximation, but embedded assumptions can distort results.
- The discussion lists commercial, broker-provided, open-source, and do-it-yourself approaches without a systematic product comparison.
- Backtest results depend on data quality, pricing assumptions, and how strategy rules are modeled.

# Are there any good tools for back testing options strategies? # Are there any good tools for back testing options strategies? There are all kinds of tools for backtesting linear instruments (like stocks or stock indices). It is a completely different story when it comes to option strategies. Most of the tools used are bespoke software not publicly available. Part of the reason for that seems to be the higher complexity involved, the deluge of data you need (option chains) and the (non-)availability of historical implied vola data. Anyway, my question: Are there any good, usable tools for backtesting option strategies (or add-ons for standard packages or online-services or whatever). Please also provide infos on price and quality of the products if possible. P.S.: An idea to get to grips with the above challenges would be a tool which uses Black-Scholes - but with historical vola data (e.g. VIX which is publicly available). ## Answer by Shane (score 17, accepted) https://quant.stackexchange.com/a/94 A few pointers: - When I looked into this a few years ago, a good solution at the time was LIM's XMIM, which also has an S-Plus/Matlab interface. Whit Armstrong also provided an R package for this, although I don't know how complete it is. This provides both the data and the software for analysis. - On the very high end (and expensive) side of the spectrum, OneTick and KDB are both being used for this purpose by professional money managers. - Two tools used by the non-professional community are available from brokers: https://www.thinkorswim.com/ or http://www.optionvue.com/. ## Answer by pangyuteng (score 5) https://quant.stackexchange.com/a/59538 Providing my 2 cents here, listing 3 free methods below: - CBOE's method: No code here, just a "white paper", thus you can code it with whatever language you desire. I kinda like this the most (disregarding how far off this could be from the reality). ``` https://www.cboe.com/publish/micropdf/CBOE-SP500-Iron-Condor-CNDR-Methodology-Paper.pdf ``` ``` https://www.quantconnect.com/forum/discussion/4478/delta-hedged-straddle/p1 ``` - home-brewed naive backtesting script. Option prices are derived using Black-Scholes. Language Python. I like this the least, but this example shows you that you can cook up a back-tester with not too much code. Not sure how usefully the backtest result could provide though, given all the baked in assumptions. The one advantage with this home-brewed method, assuming the results do reflect the reality, is that backtest with 10-years of daily price data takes no more than 15 seconds. ``` https://github.com/pangyuteng/aigonewrong/blob/main/finance/basics/poor-persons-option-backtest-attempt-0.ipynb ``` ## Answer by Vtech (score 4) https://quant.stackexchange.com/a/4637 There is one more solution available now to backtest option strategies: www.oscreener.com! This tool allows to screen and backtest bull put spreads, long calls, short puts, debit spreads etc and validate these strategies in seconds. ## Answer by delta hedge (score 3) https://quant.stackexchange.com/a/10636 Unlike backtesting stocks or futures, backtesting multi-legged option spreads does have its unique challenges. One way to backtest your options strategies is to download historical option data (Market Data Express) and use a technical analysis Excel plugin (TA-Lib). You can then create an Excel spreadsheet to automatically enter / adjust your spread trades as certain technical conditions are hit. A better way is to use an automated options backtesting software, such as (OptionStack). Using this tool, you can create rules to automatically enter and adjust your option spreads as market conditions change. In fact, you can backtest years of complex option spreads (collars, condors, etc..) in seconds. However, this software is currently in beta and there appears to be a sign-up waiting list. ## Answer by madilyn (score 2) https://quant.stackexchange.com/a/10632 There's nothing fundamentally different between options and cash instruments, so you really just need a backtesting platform that has good functionality for backtesting multiple instruments simultaneously with the same reference time frame. I'm assuming that you're looking for something halfway between in terms of level of sophistication and cost required to upkeep. One such tool that comes to mind is Deltix. ## Answer by Harry Armstrong (score 2) https://quant.stackexchange.com/a/66300 eDeltaPro is an Options Backtesting Software, specifically designed for Options traders. It has an easy-to-use user interface (no programming). Supports simple or complex multi-leg options strategies (straddles, Calendars, ratios, etc...). Has over 10 years of historical data and many symbols including Stocks, Indexes, and ETFs. You can use rolls, stop loss, and other parameters. I tested a basic strategy and then performed adjustments to see if they improved the basic setup (they did). They offer a free trial so you can test for free. I like testing any strategy before putting in actual money and see if they have performed in the past (many I tested did not work) ## Answer by QuantifyThis (score 1) https://quant.stackexchange.com/a/18529 QuantyCarlo (quantycarlo.com) is a workbench for evaluation and optimization of option trading systems. It comes in several flavors, the most basic of which allows automated options backtesting. A free version is available with a limited number of end of day symbols. Other subscription plans offer more symbols and intraday data. QuantyCarlo Enterprise Edition exposes two programming APIs, offers Factorial Analysis, Applied Predictive Modeling (see http://www.amazon.com/Applied-Predictive-Modeling-Max-Kuhn/dp/1461468485), and cluster computing to efficiently generate the optimal parameters for a given strategy. This is also offered as a service to financial institutions by IOTA Technologies (www.iotatx.com), the maker of QuantyCarlo. ## Answer by Saurabh Bhoomkar (score 1) https://quant.stackexchange.com/a/18583 I really don't know that this will work for you or not but OptionsOracle tool is worth a try !! This is the one of the best Stock options strategy trading analysis tool provided free . The code is accessible at SourceForge ## Answer by Andrew V. (score 1) https://quant.stackexchange.com/a/30159 I know this is an older post, but I found a great tool that I use. It is http://www.key2options.com. They are an online backtesting analysis platform. They offer a 3 week free trial and will do a one on one demo with you to show you how it works. ## Answer by Gordy Ostang (score 1) https://quant.stackexchange.com/a/30468 I've been using a product called AlgoNET Explorer which is by the same people who created ONE (OptionNET Explorer). I've been backtesting multi-leg options strategies with adjustments in 5min intervals using wizards and C# (VB is also supported). Much faster than manual backtesting. ## Answer by user26068 (score 1) https://quant.stackexchange.com/a/31870 ORATS offers a comprehensive scanning and backtesting tool. ## Answer by Alexander McFarlane (score 1) https://quant.stackexchange.com/a/36006 - http://www.zorro-trader.com/ - https://github.com/gbeced/pyalgotrade I found a lot of the libraries were quite lousy as for any good strategy the parameters need to be optimised to some degree and thus the portfolio might need to be "backtested" a number of times (really this isn't a backtest but more like "training") This makes a lot of libraries totally useless when they take several hours for fitting parameters to a minute-by-minute algo-strategy. ## Speed - Zorro trader is a bit awkward as I have a Linux machine and it is a Windows compiled C++ program. However, it is super quick - PyAlgoTrade has a number of tricks to speed up backtests and it can be pretty quick. ## Flexibility Both allow the use of arbitrary market input data. This allows you to create random stressed scenarios as well as use your own market data. ## Answer by vonjd (score 1) https://quant.stackexchange.com/a/63900 I published a blog post on how to backtest options strategies with R: Backtesting Options Strategies with R In the post, I provide the fully documented R code for your own experiments. The "trick" indeed is to use the often publicly available implied volatility as a proxy for option prices. For details please consult the post. ## Answer by Con Fluentsy (score 0) https://quant.stackexchange.com/a/85535 If you have a tastytrade account,they offer free options backtesting to their brokerage clients,you just need to open account. It is similar to Orats backtester,but not as complex.
