The Candl app is a browser-based stock trading simulator that teaches real investing mechanics
without any real money on the line. Instead of tracking real-world tickers, Candl generates
synthetic companies and puts them through procedurally-driven market regimes (bull runs,
crashes, sideways grinds, and everything in between), so every session plays out differently
and no one can simply memorize what happened to a real stock in the past.
How it works
You start with virtual cash and a live chart, watchlist, and newswire. Buy, sell, short, and
cover positions, set stop-losses, and react to macro events, sector rotation notes, and
company-specific news as they break. An AI advisor and AI-generated newswire (in supported
modes) add live market commentary and coaching, so the practice feels closer to reading a
real terminal than clicking through a static tutorial.
Who it's for
Candl is built for anyone who wants to learn how markets behave before risking real capital:
students learning investing fundamentals for the first time, teachers running a classroom
exercise on market cycles, and casual players who just want a fast, honest trading game.
Ways to play
Campaign mode walks through a scored sequence of scenario-driven levels, each
graded on the trading decisions you make. Learn mode pairs short lessons with
guided, step-by-step prompts and quizzes so new concepts stick immediately. Infinite
mode generates an endless procedural market for open-ended practice, and a dedicated
classroom mode lets teachers host a live lesson for a roster of students in real time.
Candl runs entirely in your browser at candlapp.org:
no download, no signup required to start, and no real money at risk.
