What Is TradeRange?
A free platform for practising trading decisions through games, not a fake brokerage account.

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.
