Frequently asked
Does Pro activate immediately after upgrade?
Pro features activate the moment payment is confirmed. Full universe, unlimited backtests, and unlimited storage become available right away.
Will my data disappear if I cancel?
Saved portfolios remain after you revert to Free. Portfolios that include Pro-only tickers (ETFs + equities) become read-only.
