About this app

How long will you keep investing on gut feeling?
Build your own trading rules without code, and test them against historical data.
Combine moving averages, stop-loss, and partial take-profit, then backtest on US and Korean daily stock data.
This app is a simulation tool for educational and entertainment purposes only. It does not guarantee future returns.

Make it a rule. Let the data answer.

■ Who it is for
- Beginners who do not know which numbers to look at first
- Anyone who wants to check a trading strategy with data instead of a hunch
- People deciding between investing a lump sum and buying in monthly
- Anyone curious whether averaging down and scaled entries actually helped
- Learners who want to study investing with evidence

■ Rule Builder
- Assemble moving-average periods, stop-loss, and take-profit with taps
- Zero coding required — build your rule in about a minute
- Supports scaled entries, scaled exits, and partial take-profit

■ Historical Backtest
- Simulation on US and Korean daily stock price data
- 1 token per stock
- Cached results — re-running identical conditions costs no extra token

■ How it works
1) Pick a stock and a period. Nasdaq names like Apple and Tesla work, and so do Korean stocks.
2) Add conditions. Buy on a golden cross, buy when it drops below a recent high, or buy
automatically every month — then set your stop-loss and take-profit levels.
3) Run it. You get cumulative return, win rate, and maximum drawdown as charts,
plus a comparison against simply buying and holding over the same period.

■ Result Analysis
- Cumulative return chart
- Buy/sell points marked on the chart
- Key metrics: maximum drawdown, win rate, average holding period
- Apply one rule across several stocks to see where it worked and where it did not

■ Share Rules
- Share the rules you build with friends
- Import other users' rules and backtest them yourself

■ Tokens
- 4 token packs: 10 / 33 / 115 / 600 tokens
- Larger packs include more bonus tokens

■ FAQ
- Can I place real trades? No. This app is not connected to any broker or exchange, and no orders are sent.
- Does it recommend stocks? No. You define every condition yourself.
- If a backtest shows a high return, will that repeat? No. It is a simulation on past data and may differ from the future.
