A double bottom is a common chart pattern traders watch for when a currency pair may be finishing a downtrend and preparing to move higher. It looks like a letter “W” on the price chart: the market drops to a low, bounces, falls back to a similar low, and then rallies. When the price finally breaks above the peak between the two lows — the “neckline” — many traders interpret that as confirmation the downtrend has failed and a bullish reversal may be underway. Before using the pattern in live trading, remember that trading carries risk and this is not personal trading advice.
What a double bottom tells you
When a double bottom forms after a sustained decline it signals that sellers tried twice to push price lower but failed to hold a new low. That repeated failure suggests selling pressure is weakening and buyers are stepping in at the same support area. The pattern is not a guarantee of a trend change; instead it increases the probability of a reversal because supply has been tested and appears exhausted.
A few practical points help set expectations. The two lows rarely match exactly; a second low that is within a small percentage of the first is usually acceptable. The more time that passes between the lows (hours to days on intraday charts, days to weeks on daily charts), the more weight many traders give the pattern. Double bottoms are more reliable on higher timeframes such as daily or weekly charts, while intraday formations tend to produce more false signals.
How to identify a double bottom on your chart
Identifying the pattern is straightforward visually, but you should follow a few steps to make the signal actionable. First, look for a downtrend or clear prior downward move that produces a low. Second, watch for a bounce that creates a swing high (the midpoint). Third, wait for a second decline toward the earlier low that either matches or comes close to it. Finally, draw a horizontal line across the midpoint to mark the neckline. A close above the neckline is often treated as pattern confirmation.
For example, imagine EUR/USD falls from 1.1200 down to 1.0800 (first low), bounces to 1.1000 (midpoint), then pulls back to 1.0820 (second low). The neckline sits near 1.1000. A daily close above 1.1000 is the breakout signal many traders require to consider a long position.
Measuring the target and where to place stops
Traders commonly use the pattern’s height to set profit projections. Measure the distance from the neckline down to the lower of the two lows, then add that distance to the breakout point above the neckline. That gives a simple measured-move target. Using the EUR/USD example: neckline at 1.1000, lows near 1.0800 → distance 0.0200 (200 pips). A conservative price target after a confirmed breakout would be roughly 1.1000 + 0.0200 = 1.1200.
Stop-loss placement usually sits below the structure where it’s clear the pattern has failed. A conservative stop is placed a little below the second low (for example, several pips below 1.0820). More aggressive traders may use a tighter stop beneath the midpoint or the pattern’s midpoint swing low, but that increases the chance of being stopped out by normal volatility. Always size positions so a stop loss corresponds to money risk you can accept on the trade.
Ways traders enter a double bottom trade
Traders use several entry approaches depending on their appetite for risk and desire for confirmation. The most cautious approach is to wait for a daily or chosen timeframe close above the neckline and then enter on that confirmed breakout. Some traders prefer to wait for a retest of the neckline after the breakout — price often returns to the broken resistance, which becomes support, and a successful retest provides extra confirmation. More aggressive traders enter on the breakout candle itself or even earlier during the second bounce, accepting a higher probability of false breaks in exchange for a better risk-reward if the pattern works.
Which approach you choose depends on your timeframe, trading plan and how much noise you expect on the chart. In all cases, combine the entry with a stop-loss and a defined target so the trade has a clear risk-reward profile.
Confirmation tools and filters
Many traders add one or more confirmation tools to reduce false signals. Useful confirmations include volume, momentum indicators, and trend analysis. Volume that increases on the break above the neckline is a classic supporting signal because it indicates greater buying interest. Momentum indicators such as RSI or MACD can show bullish divergence — for example, price makes a similar low while RSI forms a higher low — which supports the reversal idea. Trend filters like moving averages help determine whether the breakout aligns with a broader bullish shift.
Common confirmation tools traders use:
- Volume or tick activity showing rising participation at the breakout
- RSI or MACD bullish divergence during the second low
- A higher timeframe showing the pair is testing a longer-term support or reversing
Use these tools as confluence rather than absolute rules; their absence doesn’t automatically invalidate a pattern, and their presence doesn’t guarantee success.
A concrete example, step by step
Suppose GBP/USD has been falling from 1.3500 to 1.3000 over several weeks. It bounces to 1.3200, then drops again to 1.3030 before rallying. Draw a neckline at 1.3200. If the pair closes above 1.3200 on the daily chart and the breakout day shows higher volume, many traders will take that as a confirmed double bottom. Measure from neckline (1.3200) down to the lower low (1.3000) = 200 pips. A reasonable initial target would be 1.3400. Place a stop-loss a bit below the second low (for instance 1.2990) and size the position so the money you risk equals your predetermined maximum loss.
If the price breaks above 1.3200 and then returns to retest that level successfully (price bounces upward off the retest), that retest can be used to enter with a slightly better risk-to-reward profile.
Common mistakes traders make
Traders often fall into a few recurring errors when working with double bottoms. Entering before any breakout confirmation invites false-breakouts, where price briefly crosses the neckline and then reverses. Using the pattern on very low timeframes without adjusting risk can be problematic because noise is higher and patterns are less reliable. Ignoring context — for example, trying to trade a double bottom inside a strong overall downtrend — increases failure rates. Finally, failing to apply sensible position sizing and stop placement turns a reasonable pattern into an account risk.
Typical mistakes include:
- Entering before a confirmed close above the neckline
- Trading the pattern on very low timeframes without adjustments
- Neglecting volume and momentum confirmation
- Poor risk management or oversized positions
Risks and caveats
A double bottom raises the probability of a bullish reversal, but it does not guarantee one. False breakouts are common: price can clear the neckline briefly only to resume the prior downtrend. News events, central bank decisions and macroeconomic surprises can invalidate patterns in an instant. Timeframe matters — patterns on daily or weekly charts are generally more meaningful than those on 1‑minute or 5‑minute charts. Finally, using the pattern without a clear risk plan exposes you to larger-than-expected losses. Always use stop-loss orders, control position size, and treat the double bottom as one piece of evidence among many.

Key Takeaways
- A double bottom is a “W”-shaped bullish reversal pattern that forms when price tests a support area twice and then breaks above the midpoint (neckline).
- Confirm the pattern with a close above the neckline, and look for volume or momentum signals to reduce false breakouts.
- Measure the pattern height from neckline to lows to set a rough target, and place stops below the second low; always manage position size and risk.
- Trading carries risk; this information is general education and not personal trading advice.
