ChartStreak is a chart game built on real market history. You see a slice of a real chart with the dates hidden, and you call where the price will be seven candles later. Then the rest of the chart plays out. HOW A DAY WORKS • Five charts a day, one from each market: crypto, forex, indices, stocks and commodities. • 30 seconds per chart. Tap the chart to set your forecast, submit, and see what really happened. • Your score compares your call with the plain “no change” forecast on the same chart, scaled to how volatile that chart was. • All five charts count. Keep your streak going day after day. • The daily challenge needs a linked email; Price forecast, the trading simulator and shared charts work without one. • The day’s top 3 can get a badge, and streaks of 7 and 30 days get one too. WEEKLY TOURNAMENT • Your best 5 days out of 7 make your weekly score. • The week’s top 5 can receive rewards in premium days, under the tournament rules. • Entry is free and automatic: a day counts once you answer at least three of its charts. PRACTICE BETWEEN DAYS • Price forecast: single charts from crypto, forex, indices, stocks and commodities. • Trading simulator: step through a chart candle by candle, open and close trades with your own position size and see your P&L. CHALLENGE FRIENDS Share a finished day or training round as a “play my chart” link. Friends play your charts and land on a mini leaderboard with you. A training round on intraday charts or with a longer history needs premium to play. PREMIUM • Unlimited training and simulator runs. • Pick the market, instrument, era and timeframe, including 4-hour, hourly and 15-minute charts. • Indicators (MA, EMA, BOLL, RSI, MACD, Supertrend) and chart drawing in Price forecast and the trading simulator. • Run journal and metrics. Premium is an auto-renewing monthly subscription. New subscribers may start with a 7-day free trial if the App Store offers it: payment is charged to your Apple ID when the trial ends, or at confirmation of purchase if there is no trial. It renews unless turned off at least 24 hours before the end of the current period, trial included; manage or cancel it in your App Store account settings. ChartStreak is a game for education and entertainment. It is not investment advice, and nothing in it is a recommendation to buy or sell anything. Charts are historical; no real money is traded. Apple is not a sponsor of the ChartStreak tournament and is not involved in it in any way.
