What is backtesting software?
Backtesting software lets investors and traders test historical strategy rules, portfolio allocations, options setups, or discretionary trading workflows before using them live.
How is this different from charting or trading software?
Charting software helps visualize markets, and trading software helps route orders. This page focuses on testing historical assumptions, rules, simulations, and replay workflows.
Are portfolio backtesting tools included?
Yes. Portfolio simulators are included when historical allocation testing, rebalancing assumptions, cash flows, or risk and return analysis are central to the product.

Curation & Accuracy
This directory blends AI‑assisted discovery with human curation. Entries are reviewed, edited, and organized with the goal of expanding coverage and sharpening quality over time. Your feedback helps steer improvements (because no single human can capture everything all at once).
Details change. Pricing, features, and availability may be incomplete or out of date. Treat listings as a starting point and verify on the provider’s site before making decisions. If you spot an error or a gap, send a quick note and I’ll adjust.
