Stock Trading Journal
A kid buys and sells on real prices, and writes down 'why I bought it' every single time.
Why I built it
Stocks in the news, numbers going up and down — it's all distant to a child. I wanted them to feel the rhythm of buying, selling, and waiting without risking real money, and above all to build the habit of writing down 'why did I buy this?'
What it does
- Each kid trades through their own account, linked to real Korean market prices (KOSPI/KOSDAQ).
- Every order requires a reason for buying or selling — that's the heart of the trading journal.
- See daily profit and loss and current holdings at a glance.
- Real commissions and taxes are factored in to keep it close to the real thing.
- Stock detail views (candles, moving averages) to read the trend.
Who it's for
Families who want kids to safely build the habit of investing and reflecting on 'why I decided that'
Where it is now
The first set of features is finished and verified end to end locally — it's right before deployment. I'm sorting out the scope and method for opening it up.
