Chart Patterns

A chart pattern scanner looks through stock charts for classic technical patterns, such as head and shoulders, triangles, wedges and flags, so you do not have to check charts one by one. This one scans the daily charts of liquid US stocks after each close and shows where each stock sits against its breakout line, its measured move target and its stop.

Eighteen classic patterns: head and shoulders and inverse head and shoulders, double tops and bottoms, triple tops and bottoms, ascending, descending and symmetrical triangles, rising and falling wedges, rectangles, bull and bear flags, bull and bear pennants, cup and handle, and rounding bottoms. You can filter by pattern, direction, stage, share price and trading volume.

A pattern breaks out when the stock closes above its breakout line, or breaks down when it closes below it on a bearish pattern. A move through the line during the day does not count until the close, which filters out many false starts. Patterns still forming show how far the stock is from its line.

The measured move is the classic way to set a target for a chart pattern: take the height of the pattern and project it from the breakout line in the direction of the break. Each card shows the target, the stop where the pattern would fail, and how much of the move is already done.

Reward to risk compares how far a stock could move to its target with how far it could move against you to its stop, both measured from today's price. It always points the way the pattern does: on a bullish pattern it is the room up to the target against the room down to the stop, and on a bearish pattern it is the room down to the target against the room up to the stop. A bullish setup at $50 with a target of $60 and a stop at $45 has $10 of reward and $5 of risk, so it shows 2.0 : 1. A higher number favors a trade in the pattern's direction, so 5 : 1 on a bearish pattern favors a move down. Above about 2 : 1 is usually seen as a favorable setup. Around 1 : 1 means the possible gain and loss are about the same size, and below 1 : 1 means the stop is closer than the target, which often happens once most of the move is done. It changes every day with the price, and it says how big the possible gain is next to the possible loss, not how likely the target is.

Less reliable than most trading books suggest. In our own testing on years of daily data, most patterns on their own did not beat simply holding the market, and many breakouts fail. Use them as one input alongside the trend, volume and the wider market, not as a signal on their own. Each pattern on this page says plainly when it has failed.

Once a day, after the market closes, because patterns and breakouts are judged on closing prices. During the trading day the cards and charts also show live prices, with today's candle marked as live until the close.
