+# Changelog – GizerBridge
+
+A development history of GizerBridge, from first prototype to stable release.
+Documented to show the real problems solved along the way.
+
+---
+
+## v1.0.0 – First Stable Release (2026-05-22)
+
+### Phase 1 – First Prototype: HTTP Script
+- Built initial Python script sending trades via HTTP POST to Tralgo Analytics
+- **Problem:** Session cookie missing → HTTP 200 response but nothing appeared in Tralgo
+- **Fix:** Manually copied cookie from Firefox → worked
+- **Problem:** Cookie expired frequently → required manual copying every session
+- **Attempted:** Auto-login with username/password → failed due to 2FA + redirect loop
+
+### Phase 2 – Automatic Cookie Reader
+- Implemented automatic cookie extraction from Firefox SQLite database
+- **Problem:** Firefox installed as Flatpak stores profile under non-standard path
+  (`~/.var/app/org.mozilla.firefox/...` instead of `~/.mozilla/...`)
+- **Fix:** Added Flatpak path as fourth search location → resolved
+
+### Phase 3 – GUI Application
+- Built full tkinter GUI with system tray, settings window, and manual import
+- **Problem:** Tray icon showed as grey square on KDE/Wayland
+- **Fix:** Removed pystray dependency, switched to tkinter-only main window
+- **Problem:** Date filter failed to detect new log files
+- **Root cause:** Bug in filename parser
+- **Problem:** Trades imported with wrong date (today's date instead of original)
+- **Root cause:** Used `datetime.now()` instead of parsing date from filename
+- **Problem:** Times always showed `00:00:00` for historical trades
+- **Root cause:** Sierra Chart log files contain no time information → accepted as limitation
+
+### Phase 4 – DTC Protocol Integration
+- Pascal (Tralgo support) recommended DTC Protocol over log file parsing
+- Sierra Chart DTC server already active on port 11099
+- Replaced log file parser with direct TCP connection via DTC Binary Protocol
+- **Problem:** Prices transmitted as `raw_value / 100` → showed as `100000.00` in Tralgo
+- **Root cause:** Division by 100 missing in auto-monitor function
+- **Problem:** Trades sent twice
+- **Root cause:** Two app instances running simultaneously
+- **Fix:** Enforced single instance
+
+### Phase 5 – Simulation Account Support
+- **Problem:** DTC returned empty packets for simulation accounts
+- **Attempted fix:** Reactivated log file parser as hybrid fallback for sim accounts
+- **Retested:** DTC does deliver sim fills correctly after all → log file parser removed again
+- **Result:** DTC-only for all account types (live + sim) → stable
+
+### Phase 6 – Rebrand to GizerBridge
+- Renamed app from "Analytics Importer" to **GizerBridge**
+- Integrated GizerLabs logo (taskbar icon + header in main window)
+- Built distributable Linux AppImage (no installation required)
+- Added pystray back with correct KDE/Wayland configuration
