* feat(ibkr): compute net_market_flows from IBKR equity delta and trade flows
Replace the hardcoded net_market_flows: 0 in HistoricalBalancesSync with an
exact derivation from IBKR's own equity summary data, eliminating any
dependency on third-party security price providers for Period Return.
Formula: nmf = Δnon_cash - net_buy_sell
- non_cash = IBKR equity total - materializer cash (exact per IBKR)
- net_buy_sell = sum of trade amounts converted to base currency using
the stored fx_rate_to_base (IBKR's own FX rate, already on Trade#exchange_rate)
Sets non_cash_adjustments = net_buy_sell so the virtual column identity
(end_non_cash_balance = start + nmf + adjustments) resolves to IBKR's
exact equity figure.
* test(ibkr): add sell-trade and no-trade nmf tests; fix memoization guard
- Add test: sell trades (negative amount) correctly isolate market loss in nmf
- Add test: no-trade scenario produces nmf = full Δnon_cash
- Fix: `return {} unless account` inside ||= exited the method without memoizing;
restructure to `if account ... else {} end` so the result is always cached

* fix(ibkr): exclude dividend/interest trades from net_buy_sell; use historical FX date
Addresses two issues flagged in code review:
- P1: trades with qty=0 (Dividend, Interest) were included in net_buy_sell,
inflating/deflating nmf on dates with income events. Filter to qty != 0 at
the SQL level so only buy/sell trades affect the market-flow calculation.
- P2: Money#exchange_to defaulted to Date.current when no custom_rate was
stored, causing historical nmf to drift as FX rates change over time.
Pass date: entry.date so the fallback lookup uses the trade's own date.

* test(ibkr): cover Money::ConversionError fallback in trade_flows_by_date
Adds a test that stubs Money#exchange_to to raise ConversionError for a
cross-currency trade with no stored exchange_rate, verifying that the
rescue clause falls back to entry.amount and that nmf and
end_non_cash_balance still resolve correctly.

* fix(ibkr): log warning when FX conversion falls back to unconverted amount
When Money::ConversionError is raised for a cross-currency trade with no
stored exchange_rate, warn with entry currency, account currency, date,
amount, and entry/account IDs so the silent fallback is visible in logs.
Same-currency ConversionErrors (unexpected but possible) stay silent.

* fix(ibkr): skip unconvertible FX trades, redact log, tighten join
- On Money::ConversionError, skip the entry from net_buy_sell rather
than falling back to the raw amount (which treated e.g. EUR as CHF);
nmf now absorbs the full Δnon_cash for that date instead of silently
misstating period return
- Remove entry amount, entry ID, and account ID from the FX warning log
to avoid exposing financial data in log output
- Consolidate entryable_type guard into the JOIN condition rather than a
separate WHERE clause
- Add inline comment on the first-day zero case to distinguish intent
from a bug
- Update ConversionError test to assert skip behavior (nmf=200, not 50)
* fix(ibkr): exclude dates with unconvertible FX trades from balance upsert
* fix(ibkr): skip upsert_all when all balance rows are filtered by failed FX dates

Sure: The personal finance app for everyone
Get involved: Discord • Website • Issues
Important
This repository is a community fork of the now-abandoned Maybe Finance project.
Learn more in their final release doc.
Backstory
The Maybe Finance (archived/abandoned repo) team spent most of 2021–2022 building a full-featured personal finance and wealth management app. It even included an “Ask an Advisor” feature that connected users with a real CFP/CFA — all included with your subscription.
The business end of things didn't work out, and so they stopped developing the app in mid-2023.
After spending nearly $1 million on development (employees, contractors, data providers, infra, etc.), the team open-sourced the app. Their goal was to let users self-host it for free — and eventually launch a hosted version for a small fee.
They actually did launch that hosted version … briefly.
That also didn’t work out — at least not as a sustainable B2C business — so now here we are: hosting a community-maintained fork to keep the codebase alive and see where this can go next.
Join us!
Hosting Sure
Sure is a fully working personal finance app that can be self hosted with Docker.
Forking and Attribution
This repo is a community fork of the archived Maybe Finance repo. You’re free to fork it under the AGPLv3 license — but we’d love it if you stuck around and contributed here instead.

Performance Issues
With data-heavy apps, inevitably, there are performance issues. We've set up a public dashboard showing the problematic requests seen on the demo site, along with the stacktraces to help debug them.
