TradeLog - Per-Trade Journal

A trading journal for people who buy in tranches instead of all at once. "What's your average price?" has an answer. "Was your second buy any good?" usually doesn't. TradeLog logs every buy as its own tranche and scores it on its own. Nothing gets folded into a single average cost. ▣ Per-tranche returns — the whole point Buy the same stock three times and you see three separate results: 1st -5.5% / 2nd +4.2% / 3rd +11.8%. A single average price would have flattened all of that into "+4%". Here you can see which buy actually worked and where you got stuck. ▣ Currency comparison Overlay USD, JPY, EUR and CNY against the Korean won on one chart. Switch the range from one month to five years, and compare today against your own average entry rate before you buy again. ▣ Base currency Show your totals on Home, History and the Report card in USD, JPY, EUR or CNY instead of KRW. ▣ Stocks and currency, both in tranches Korean stocks, US stocks — and USD, JPY, EUR and CNY currency buys too, each split into tranches with its own exchange-rate gain. Register a ticker and your unrealized P/L follows Naver Finance quotes on its own. ▣ Bring the spreadsheet you already keep Import and export CSV, so an existing history moves in and your records can always move out. ▣ Report card Realized P/L, realized return, win rate and average holding days by period. Realized P/L by month, by asset and by broker, a cumulative curve, and a breakdown of which buy number tends to work out best for you. ▣ Calendar and timeline Look back at what you bought and sold, and when. ▣ Target alerts Set a target return per tranche and get notified during market hours. Buys that passed their target but are still open are collected in one list. ▣ Your records stay on your device No account, no login. Trades are never sent to a server — they are stored on your device.
