VERDICT

Should I use testfolio?

Backtest portfolios, compare asset allocations, model rebalancing and cashflows, and analyze historical risk and return with testfolio. - testfol.io

Worth it. Buy it if you're a DIY investor comparing ETF or leveraged-ETF allocations over long horizons. Skip it if you need intraday-grade accuracy, audited models, or guaranteed data persistence.
