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.

One Candle Ahead — free paper-trading practice for chart readers

One Candle Ahead is an educational trading simulator that reveals real historical market data one candle at a time. The goal is simple: read the visible chart, make a decision, reveal the next candle, and learn from the result without risking real money.

What you can practice

The simulator is built for beginners and self-directed learners who want practical repetitions with candlestick structure, trend context, support and resistance, RSI, moving averages, Bollinger Bands, VWAP, volume, position sizing, and trading psychology. Articles in the trading education blog explain each concept in plain language, then the simulator lets you test the idea against historical stock and crypto charts.

Each session uses virtual currency only. There are no deposits, withdrawals, brokerage accounts, exchange accounts, real orders, or real-money trades. Results are educational practice records, not investment performance.

How the one-candle loop works

Choose a stock or crypto practice mode.
Study the visible chart and decide whether the next candle favors patience, buying, selling, or risk reduction.
Reveal the next candle and compare the outcome with your original reasoning.
Repeat the loop to build pattern recognition, discipline, and review habits.

This loop is intentionally slower than live trading. It creates space to explain why a decision was made instead of rewarding random clicking.

Original education content

The One Candle Ahead blog includes original guides on candlestick patterns, RSI, moving averages, Bollinger Bands, MACD, paper trading, support and resistance, volume, crypto versus stocks, trading psychology, and risk management. These guides are written to connect directly to simulator practice rather than repeat generic definitions.
