Testfol.io is a freemium web-based portfolio backtesting and analysis toolkit for investors who want to test allocations, cashflows, rebalancing rules, tactical signals, leverage, correlations, and historical risk/return.

Backtests depend on historical assumptions and end-of-day data, so they are not trade execution or forward-looking guarantees.

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.

Are portfolio backtesting tools included?
