Built for post-trade work
Your exchange shows fills. AfterFill shows behavior.
Exchanges are built for execution. AfterFill is built for the quiet work after it: reconstructing trades, counting every fee, measuring risk, and spotting the habits that damage expectancy.
Risk discipline
Compare planned risk with realized loss, leverage, position size, stop behavior, and time in trade.
Costs that matter
Track fees and funding beside gross profit so small targets, funding drag, and cost-heavy symbols are visible.
Decision history
Attach rationale, screenshots, tags, corrections, and review notes to the actual timeline of fills and ledger events.
Hands-on
Review a trade. Right here.
This is the actual guided flow from the app — story, plan, execution replay, lesson — running on mock Kraken data. Change the stop and watch the outcome change.

Kraken-first workflow
Read-only in. Discipline out.
v1 starts with Kraken and stays read-only toward exchanges. AfterFill imports account history through a daily scheduled sync, keeps a force refresh button, and rebuilds derived trades without ever mutating raw exchange records.
- 01
Connect read-only Kraken keys
AfterFill guides key setup, rejects risky permissions when detectable, and stores secret material server-side only.
- 02
Refresh imports daily
A daily scheduled sync updates connected accounts, with a force refresh button available. v1 has no automated exchange actions.
- 03
Normalize raw events first
Fills, ledger entries, fees, funding, balances, and positions are stored before derived trades are rebuilt.
- 04
Review trades and behavior
Annotate rationale, mistakes, R-multiple, costs, corrections, and export clean review history.
Security boundary
Designed for review, not execution.
AfterFill never needs trade or withdraw permissions. Exchange credentials stay server-side, sync logs are sanitized, and user-owned data is scoped by authenticated accounts.
No trading permissions
The product is read-only toward Kraken. v1 does not place orders, cancel orders, or request withdrawal access.
Server-only exchange secrets
API key material is kept out of client code, browser storage, public runtime config, and user-visible logs.
User-scoped data model
Review data is scoped server-side by authenticated user, with RLS policy design planned for every user-owned table.
Bring discipline into the same rhythm as execution.
The first release is intentionally focused: Kraken import, daily refresh, trade reconstruction, risk review, fee and funding analysis, and review corrections.
