Most traders' "journal" is a folder of screenshots and a notes app they never reopen. Tapeline puts the chart and the reasoning in the same place — so reviewing your own trades becomes something you'd actually do.

Every entry pairs a chart screenshot with the numbers and the story behind it. Six months from now, you're not just staring at a win or a loss — you're looking at exactly what you saw at the time, and why you took the trade.

What's inside:

• Full trade log — symbol, date, timeframe, direction, entry/exit price, custom tags

• Automatic P&L%, color-coded at a glance

• Chart image on every entry, right next to your notes

• Optional AI Chart Analysis — connect your own Anthropic API key for a concise technical read on any chart you upload, editable before you save

• Filter and sort by symbol, direction, tag, or performance

• Win rate and average P&L calculated automatically

• Export to CSV or JSON — your full journal, images included, portable across devices
