What Is TradeRange?
A free platform for practising trading decisions through games, not a fake brokerage account.
Updated 4 Nov 2026
TradeRange is a free web app built around two things: a custom ETF backtester for testing longer-term portfolio ideas against real price history, and a set of daily stock-market puzzle games for practising short-term decisions. "Markets close. Games stay open" is the site's own way of putting it.
The custom ETF backtester
Pick any tickers, set weights, choose a rebalancing schedule and an initial investment, and run the combination against up to a decade of real historical price data.
- CAGR and total return
- Sharpe and Sortino ratios
- Maximum drawdown
- Monthly return heatmap
- Sector, market-cap and geographic exposure
- Benchmarking against SPY, QQQ, VTI, VOO and VT
The daily games
A new puzzle appears each day for every one of these, and everyone worldwide sees the same one — you get six tries and a spot on the global leaderboard.
- Stockle — guess the daily stock in six tries from info by categories.
- CandleDojo — identify the daily candlestick pattern in three tries.
- CandleDirect — eighteen real 15-minute candles visible, eight hidden; call up or down and score in seconds.
- AlgoBattle — trade a 15-minute session against a real trading algorithm and try to beat the machine.
- Buel — Kahoot-style multiplayer candle duels; create a room and race friends to read the chart first.
- Stockle Multiplayer — team version where one player sets the ticker and the rest take turns guessing.
ℹ
Same puzzle, everyone, every day
Every daily puzzle rotates on a deterministic schedule, so the whole global leaderboard is competing on the exact same chart each day — not a random pull each user gets individually.
Is it free?
Yes. Building and backtesting portfolios, and playing every daily game, is free. A free account saves your portfolios and tracks your game scores over time.
Where to start
New to charts entirely: start with Stockle or CandleDojo. Already comfortable reading a chart and want reps on calling direction: CandleDirect or AlgoBattle. Thinking in months or years rather than single trades: the custom ETF backtester is where that question gets answered.
