Stop reading about candlestick patterns and start recognising them. tradeguessr shows you real historical charts, asks you to predict the next move, and scores your accuracy instantly.
A candlestick pattern practice simulator is an interactive tool that presents you with real historical price charts and challenges you to predict future price movement. Unlike static textbook diagrams, a simulator forces you to apply your knowledge under realistic conditions — the same way a flight simulator trains pilots before they ever touch a real cockpit. tradeguessr uses genuine OHLC (open, high, low, close) data sourced from Polygon.io, so every chart you see reflects actual market behaviour, not a hand-drawn example.
Textbook candlestick patterns are always drawn perfectly: the hammer has a flawless 3:1 wick-to-body ratio, the engulfing candle completely swallows the previous one. Real markets are messier. A hammer might have a small upper wick. An engulfing pattern might appear in the middle of a choppy range rather than at a clean trend bottom. Practising on real data trains your eye to recognise patterns in their natural, imperfect state — which is the only skill that translates to live trading.
Each round presents you with 40–60 candles of historical price action, with the final 10–15 candles hidden. You drag a price target to where you believe the chart will close. After submitting, the hidden candles animate into view and your score is calculated based on how close your target was to the actual closing price. You earn up to 1,000 points per round across 5 rounds. The scoring system rewards precision: a target within 0.5% of the actual close earns a near-perfect score, while a target more than 5% away scores near zero.
Yes. tradeguessr is completely free to play with no account required. You can complete a full 5-round session, see your score, and compare it against the global leaderboard without creating an account. Creating a free account lets you save your scores across sessions and appear on the permanent leaderboard. A Pro upgrade is available for traders who want unlimited access to the Trading Dojo pattern-recognition drills, but the core simulator is always free.
Because tradeguessr uses real historical data rather than curated examples, you will encounter the full spectrum of candlestick patterns that appear in live markets: hammers, shooting stars, doji, bullish and bearish engulfing patterns, morning and evening stars, bull flags, bear flags, head-and-shoulders formations, double tops, double bottoms, ascending and descending triangles, and many more. The variety is determined by what actually happened in the market, not by what a textbook author decided to include.
