A custom chart builder, Trade Analysis rebuilt, and Tax Calculator upgrades

A new custom chart builder, per-lot Trade Analysis, Interest Tax and dividend-by-country calculators, more companies with full financial data, and a Watchlist table upgrade.

📊

Custom chart builder

The new Charts page lets you pick any metric from a company's fundamentals or price history and plot several of them together as bars, lines, or areas. You can save your own templates or reuse the provided ones, like Price vs EPS or FCF comparisons, whenever you want to look at that combination again.

🧮

Tax Calculator upgrades

A new Interest Tax card calculates what you owe on interest income the same way the Dividend Tax card already does, netting off broker withholding against your tax rate. The Dividend Tax card also got a Holdings/Country toggle, so it is in the same format as some tax forms require.

💹

Trade Analysis rebuilt

Trade Analysis now tracks every position lot by lot, so you can expand any trade to see the individual buys that make it up, each with its own cost, gain, and holding period. You can also now see the FX impact on your trades and customize the columns you want to see.

🌍

More companies with full financial data

EDP now has full financial statements, joining Navigator, Galp and EDP Renováveis on the PSI-20 side. On the international side, we are also continuing to expand our coverage of larger caps. You can expect more companies going live every week.

📈

Watchlist table upgrade

Watchlists gained six new columns: Day Change, P/S, Dividend Yield, Net Margin, Debt/Equity, and Net Cash, all customizable like the rest of the table.
