tradeguessr is the free candlestick pattern trainer that works in your browser — no download, no account required. Study real charts, place your price target, and get scored on your accuracy.
A good candlestick pattern trainer should do three things: present you with real, unedited chart data; require you to make a concrete prediction rather than just name a pattern; and give you immediate, quantitative feedback on how accurate your prediction was. Most apps on the market fail on at least one of these criteria — they use synthetic charts, they ask multiple-choice questions, or they give vague qualitative feedback. tradeguessr is built around all three requirements.
Browser-based training has a significant advantage: zero friction. There is no installation, no account creation required to start, and no compatibility issues across devices. You can open tradeguessr on your laptop before a trading session, on your phone during a commute, or on any computer without needing to install anything. The charts are rendered on an HTML5 canvas element, which gives smooth, responsive performance equivalent to a native app.
Because tradeguessr uses real historical data, the patterns you encounter are determined by what actually appeared in the market — not by a curated list. In practice, you will regularly encounter bull flags, bear flags, hammer reversals, engulfing patterns, doji formations, and triangle breakouts, because these are the patterns that appear most frequently in real price action. Less common patterns like head-and-shoulders or morning stars appear less frequently, which accurately reflects their rarity in live markets.
A full 5-round session takes approximately 5 to 10 minutes depending on how long you spend analysing each chart. Each round presents you with a chart, waits for you to place your target, and then reveals the outcome. There is no time limit, so you can take as long as you need to study the chart before committing to a prediction. Most experienced traders complete a round in under 2 minutes; beginners often spend 3 to 5 minutes per chart.
Yes, with a caveat. If you have never seen a candlestick chart before, you may want to spend 20 minutes reading a basic introduction to OHLC charts before your first session. tradeguessr does not include a built-in tutorial on what candlestick patterns mean — it is a practice tool, not a classroom. Once you understand the basics of what open, high, low, and close represent, and what a few common patterns look like, tradeguessr is an excellent way to develop your recognition speed and accuracy through repetition.
