§ AUTO-SYNC
Stop typing your trades. Sync them.
Manual trade logging is where journaling dies — you skip the losers, backfill from memory, and lie to yourself by Friday. Postmortem connects to your exchange with a read-only API key and pulls every fill automatically, grouping them into round-trip trades with realized P&L, fees and R-multiple already calculated.
Every fill, every few minutes — no manual entry
Paste a read-only API key once. Postmortem polls your exchange and reconstructs closed trades from your fills — entry, exit, size, leverage, fees and net P&L — so your journal is complete without you touching a spreadsheet.
Open positions show live unrealized P&L that refreshes automatically, so your dashboard reflects your real account, not a stale snapshot.
Seven exchanges, read-only, never withdrawal
Supported: Binance Futures, Bybit, OKX, MEXC, Bitget, BingX and Bitunix. Always create the API key with trading and withdrawals disabled — Postmortem only needs to read your history.
Requests are signed in your browser; your secret is stored encrypted (AES-256) so your connections follow you to another device, and only your logged-in session can retrieve it.
A verdict on every synced trade
Synced trades run through the same analysis as everything else: a plain-language verdict (CLEAN / FLAGGED / MIXED), automatic mistake tags (no stop, oversized, revenge trade, held through funding), and per-setup performance once you tag them.
FAQ
Is my API key safe?
Keys are read-only and requests are signed in your browser. The secret is stored encrypted (AES-256) so only our server can decrypt it and only your session can request it. Always disable trading and withdrawal permissions when you create the key.
Which exchanges are supported?
Binance Futures, Bybit, OKX, MEXC, Bitget, BingX and Bitunix — all via read-only API keys.
How often does it sync?
Automatically while the app is open, and it back-fills anything that closed while it was shut the next time you open it.
