Build an AI trading journal for retail traders in stocks, forex, crypto, and futures. 1. Fast trade entry through a one-screen form: symbol, direction, entry, exit, size, fees, and a required after-trade note covering the setup, emotion, and mistake. 2. Photo and CSV import so users can log trades from brokerage screenshots or export files without retyping. 3. Auto-computed performance dashboard: win rate, average R multiple, profit factor, expectancy, drawdown, and best and worst setups. 4. AI pattern detection that groups trades by setup type and tells the user which setups actually make money versus which they only think work. 5. AI weekly review that reads the week's trades and writes a coach-style debrief covering discipline, position sizing, and emotional triggers. 6. Mistake and tilt tracker that flags repeated errors like revenge trading, oversizing after losses, or moving stops. 7. Tag system for setups, timeframes, and emotional state, with filtering on every screen. 8. Calendar heat view showing profit and loss by day, day of week, and time of session. 9. Private notes with a locked diary mode for strategy and mindset reflections. 10. Weekly digest email summarizing stats and the AI debrief. Never generate buy or sell signals or price predictions; the tool reviews past trades only and is not financial advice.
