Trading Practice Journal

Trading Practice Journal turns chart practice into a record you can actually learn from. If you practise on replay, you have probably noticed the hard part is not taking the trades — it is remembering what you were thinking three weeks later. Notes in a spreadsheet lose the chart. Screenshots in a folder lose the reasoning. This extension keeps both together, in a side panel that sits right next to the chart you are studying. HOW IT WORKS 1. Open the journal in the side panel next to your chart. 2. Mark market structure per timeframe — trend or range, and direction — from the weekly down to the 15-minute. 3. Press Capture. The extension screenshots the chart you are studying and reads your entry, take-profit and stop-loss straight off the drawn position boxes, so you do not have to retype them. 4. Tag the trade with your reason and the result. 5. Open the Review tab to see what your habits actually look like. WHAT YOU GET • Per-timeframe structure notes, from weekly to 15-minute, in one session view • Up to 20 trades per session, each with before and after screenshots • Automatic price extraction — entry, take-profit and stop-loss are read from the chart image, with risk-reward and return calculated for you • A Review tab with cumulative P&L, trade cadence, and breakdowns by timeframe, by hour of day, and by symbol • Click any screenshot to zoom and pan it full size • Works in the side panel or as a full tab, whichever you prefer • Export and import your whole journal as a ZIP, any time • Optionally mirror everything to a folder on your own disk, as plain PNG and JSON files you can read without this extension YOUR DATA STAYS ON YOUR MACHINE There is no server, no account, no sign-up, and no analytics. The extension makes no network requests at all. Screenshots and journal entries are written to your browser's local storage and, if you choose, to a folder you pick yourself. Nothing is ever uploaded, because there is nowhere for it to be uploaded to. Even the text recognition runs locally — the engine that reads prices off your screenshots is bundled inside the extension and processes images on your own device. The full source code is public if you want to verify any of that yourself: https://github.com/JFFOS/trading-journal-extension GOOD TO KNOW • Built for practice and replay, not for placing orders. It cannot connect to a broker and cannot trade. • Price detection reads the coloured position boxes you draw on the chart. If you use an unusual chart theme, you can set the exact colours in Settings. • Works with TradingView, or with a self-hosted chart you run yourself.
