Questions people ask

What is One Candle Ahead?

One Candle Ahead is a free game where you practice reading stock and crypto charts. You see real historical price data one candle at a time, decide what to do, and learn from what actually happened, without risking real money.

Is One Candle Ahead really free?

Yes. Playing on the web is free. The iOS and Android apps are free too, with optional in-app purchases.

What market data does the game use?

Daily price history (open, high, low, close, volume) for about 100 US stocks since 2020, and 13 major cryptocurrencies such as BTC, ETH and SOL from Binance. Each round starts at a random point in that history, so you cannot memorize outcomes.

Do I need an account to play?

No. You can play as a guest. Signing in with Google saves your balance, rank and achievements across devices.

Does it work on mobile?

Yes. The website works on phones, and there are native apps for iOS and Android.

Will this make me profitable in real trading?

No game can promise that. One Candle Ahead helps you practice reading charts and making decisions calmly. Real trading adds fees, slippage, news and emotion, so treat it as practice, not a prediction tool.

One Candle Ahead is a game for learning and fun. It uses virtual money only and is not financial advice. Past prices do not predict future results.
