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.

Free trading calculators for risk-first practice

Calculate account risk, units, position value, and risk/reward before practicing a setup. These tools are educational and designed for paper-trading workflows, not financial advice.

Position size calculator

Enter account size, risk percentage, entry price, and stop price to estimate the number of shares or units that fit the planned account risk.

Risk/reward calculator

Compare distance from entry to stop against distance from entry to target. A setup with a larger possible reward than planned loss is easier to review objectively.

Why calculators bring high-intent traffic

People searching for trading calculators are usually trying to solve a concrete risk-management problem. That makes the page useful for learners and valuable for internal links to the simulator and risk articles.

Limitations

Real markets include spread, slippage, fees, liquidity, taxes, and emotion. A calculator cannot predict outcomes or remove risk. Use it for learning and practice planning only.
