I've had a great experience with a few options backtesting tools, and I can definitely share some insights. One popular choice is Thinkorswim by TD Ameritrade. It’s quite user-friendly and offers a fairly comprehensive backtesting capability through their thinkBack feature. You can test various strategies and see how they would have performed historically, which can be quite insightful.
Another option to consider is OptionNet Explorer. It's known for its robust analytics and allows for quite a bit of customization in terms of strategy testing. It provides a detailed breakdown of performance metrics, which can be really helpful for tweaking and refining your strategies. However, it might take some time to fully grasp all its functionalities if you're new to the platform.
Lastly, there’s QuantConnect, which is more of a coding-based platform. This might be ideal if you're comfortable with writing scripts and want deep data analysis. The advantage here is the flexibility in terms of strategy customization, but it requires some coding knowledge.
Each of these platforms has its own strengths and weaknesses, so I would recommend trying out trials if available, to see which one aligns best with your needs. Additionally, exploring community forums for these tools can provide valuable tips and tricks from other users.
