TradeLog - Per-Trade Journal

The 42 apps

About this app

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. Lock the app with your fingerprint or face.

Made for you if
· you buy in several goes rather than all at once
· you follow a split-buy rule such as seven splits
· you average down and then lose track of what to sell
· you buy foreign currency a bit at a time

―――
Quotes come from Naver Finance (unofficial) and may be delayed. Base-currency
conversion is an approximation at the current rate; stock splits and dividends
are not applied automatically. Realized P/L is shown before fees and taxes.
This app is a record-keeping tool. It does not place orders and does not provide
investment advice.
