Rebuild the portfolio
It reads the selected activity export, works out open positions and cash, and preserves the source and import history locally.
SOFTWARE / PORTFOLIO PLANNING
A brokerage export shows the portfolio as it stands. Adjustable targets guide the rebalancing calculation with each contribution.
A broker can show balances and transactions. The investment app adds the personal plan around them, without pretending to choose investments or act on the account.
It reads the selected activity export, works out open positions and cash, and preserves the source and import history locally.
Current weights sit beside adjustable targets, with clear underweight, overweight, cash, and non-strategic positions.
A contribution can be spread across underweight holdings while respecting purchase limits and leaving any unusable amount as cash.
Strategy changes become new versions instead of erasing the old plan, and portfolio history keeps the strategy used at the time.
The app supports the thinking around a decision. It deliberately leaves research, suitability, timing, and execution outside the software.
Choose a recent brokerage activity export from the file picker.
Update market prices so holdings have current values.
Review the targets, adjust them as needed, and calculate rebalancing for the contribution.
Make any chosen transaction at the broker, then import again.
The app is used with every contribution to calculate portfolio rebalancing against adjustable targets. The account details and holdings stay private.
A real export was selected through the normal file picker and became a new saved import.
The resulting transactions and reconstructed portfolio were visible in the app after import.
Adjustable targets guide the portfolio rebalancing calculation whenever new money is contributed.
The investment app is not investment advice, a broker, or an order-entry system. It calculates against the strategy the user chose. It never decides whether that strategy is suitable and never places a trade.
