Chartle teaches you to read price charts, five minutes at a time. A real historical chart appears, cut off at the moment a pattern completed. You call what happens next, or you name the shape you are looking at. Then the outcome candles animate in, the pattern is named, and one line explains why price behaved the way it did. Five questions make a session. About five minutes. HOW IT WORKS Predict first, then find out. You commit to an answer before the chart reveals itself. Reading about a pattern and recognising one under pressure are not the same skill, and only the second one is worth having. Real market charts. 245 historical windows across 49 patterns, cut from real price history rather than drawn as textbook illustrations. Real charts are messy. Reading a messy one is the actual job. Measured, not asserted. Every pattern in Chartle carries behaviour measured across 3.2 million labelled occurrences in real market data. Where a pattern is weaker than the others, the app says so instead of hiding it. Three kinds of question. Predict the direction, name the pattern from four options, or confirm whether a chart is what it claims to be. Naming is only asked about patterns you have already met. WHAT IS INSIDE 40+ patterns, in four families. Candlestick — hammer, hanging man, shooting star, engulfing, harami, kicker, marubozu, belt hold, dark cloud cover, piercing line, morning and evening star, dragonfly and gravestone doji, tweezers, three white soldiers, three black crows. Reversal — head and shoulders, inverse head and shoulders, double top, double bottom, triple top, triple bottom. Continuation — bull flag, bear flag, ascending triangle, descending triangle, symmetrical triangle, rising and falling three methods, Tasuki gaps. Breakout — trendline breakout, trendline breakdown, support bounce, resistance rejection. Every pattern has a lesson: how it forms, what to check before you trust it, and when it fails. Lessons are written in your language, not machine translated. A DAILY HABIT One daily challenge the same five charts for everyone, every day. A streak that counts the days you turned up. Levels that reward showing up rather than being right. A mastery ring that measures how much of the catalogue you have covered, so it only ever moves forward. WHAT CHARTLE IS NOT No signals. No tips. No buy or sell calls. No entry, stop or target levels Chartle filters those out of its own charts on purpose. It is not a broker, a portfolio tracker or a trading terminal, and it never tells anyone what to buy. It teaches you to recognize what you are looking at. What you do with that is yours. FREE AND PLUS Today's challenge is free, every day, and you do not need a card to start. Chartle Plus adds unlimited practice sessions and lets you drill any single pattern on demand.
