What is One Candle Ahead?

One Candle Ahead is a free trading simulator that lets you practice stock and cryptocurrency trading using real historical market data, one candle at a time. You predict the next move, learn candlestick patterns, and build technical analysis skills without risking real money.

Is One Candle Ahead really free?

Yes. Core gameplay — stock and crypto simulations, leaderboard, candlestick charts — is 100% free. The iOS and Android apps include optional in-app purchases for cosmetic items, but nothing is paywalled.

How do you learn candlestick patterns here?

Every game reveals one candle at a time from a real historical chart. You decide whether to buy, hold, or sell. Over dozens of rounds you internalize the shape of reversals (hammer, engulfing), continuations (marubozu), and indecision (doji) in context — not just from a static chart picture.

What market data does the simulator use?

Real historical OHLCV (open/high/low/close/volume) data for major U.S. stocks (AAPL, MSFT, GOOGL, TSLA, etc.) and top cryptocurrencies (BTC, ETH, SOL). Chart windows are randomized so you can't simply memorize outcomes.

Does One Candle Ahead work on mobile?

Yes. The web app is fully responsive, and native apps are available for iOS (App Store) and Android (Google Play). The mobile apps add 14 achievements, daily challenges, PvP duels, referral rewards, and a seasonal leaderboard.

Will this make me profitable in real trading?

No simulator can guarantee real-market profits. One Candle Ahead trains pattern recognition and disciplined decision-making — two foundations of good trading — but real money involves slippage, fees, news, and emotion. Use it as practice, not a crystal ball.

Do I need an account to play?

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

People ask "is One Candle Ahead like TradingView?" — the honest answer is no. They look similar (both show candlestick charts) but they solve completely different problems. Here is the split.

Two side-by-side mini-charts contrasting a slow, calm trend against a fast, volatile one — illustrating style or market differences.

TradingView vs One Candle Ahead: analysis workbench on one side, forced-decision training floor on the other.

What TradingView is for

TradingView is a professional charting platform. Real-time data across stocks, crypto, forex, and futures. Pine Script for custom indicators. Community ideas and public chart sharing. Broker integrations for live trading. It is the Swiss Army knife of market analysis.

What One Candle Ahead is for

One Candle Ahead is a prediction-based trading simulator. Real historical market data, chart windows randomized so you cannot memorize outcomes, and a forced decision on every candle. The goal is not to analyze — it is to train recognition under pressure with immediate feedback.

Where the overlap ends

Real-time market data: TradingView wins — One Candle Ahead uses randomized historical data.
Custom indicators: TradingView wins — Pine Script is powerful.
Social/community: TradingView wins — idea feed and public charts.
Forced-decision practice: One Candle Ahead wins — TradingView does not quiz you.
Leaderboard pressure: One Candle Ahead wins — status stakes make you focus.
Mobile-first practice: One Candle Ahead wins — dedicated iOS and Android apps.
Price: Tie — both have free tiers, TradingView has paid plans for advanced features.

The real workflow

Use both. Analyze live markets on TradingView — find setups, mark levels, read the tape. Then drill on One Candle Ahead — reps, pressure, feedback. Analysis without practice is daydreaming; practice without analysis is gambling. You need both.

Frequently asked questions

Is One Candle Ahead free?

Yes. Core gameplay — stock and crypto simulations, leaderboard, charts, indicators — is 100% free on web, iOS, and Android. Mobile apps include optional cosmetic in-app purchases but nothing is paywalled.

Can I use TradingView charts inside One Candle Ahead?

No. One Candle Ahead uses its own chart renderer (lightweight-charts under the hood) because the simulator needs to hide future candles and control the reveal — not possible with an embedded third-party chart.
