The piercing line pattern is a two-candle bullish reversal pattern that forms at the end of a downtrend. A long bearish candle is followed by a bullish candle that opens lower and closes above the midpoint of the first candle's body, which shows buying pressure pushing back against sellers.
Traders use the piercing line to spot a possible end to the downtrend, then confirm it with a key level, RSI bullish divergence or a volume spike before buying.
What Is the Piercing Line Pattern?
The piercing line pattern, also called the piercing pattern, is a two-candle bullish reversal pattern in candlestick price action technical analysis. It appears after a downtrend and signals that the downtrend may be ending and an uptrend may start.
The first candle is a long bearish candle, usually shown in red or black. The second candle is a bullish candle, usually shown in green or white, that opens lower and then climbs to close above the midpoint of the first candle's body.
The pattern is only complete when the second candle closes. A second candle that is still forming can fall back below the midpoint before the session ends.
The piercing line is a bullish pattern only. Its bearish equivalent is the dark cloud cover, which is compared later in this guide.
How to Identify a Piercing Line Candlestick?
A valid piercing line candlestick needs five things to be true. Check each one on the chart before treating the pattern as a signal.
Measure the midpoint on the first candle's body only, from its open to its close. Including the wicks moves the midpoint and can make a weak second candle look valid.
How deep the second candle closes into the first candle's body also matters. A close just above 50% is the minimum, while a close near 80% of the body shows stronger buying pressure and is more likely to lead to a reversal.
The classic textbook version is stricter: the second candle opens below the first candle's low and leaves a clear gap down. This is the more reliable version of the pattern, and it shows up most often on stock charts, where price can gap between one trading day and the next.
Forex and other 24-hour markets rarely show that gap, because the next candle usually opens at or very near the previous close. On these charts, a second candle that opens about level with the first candle's close is good enough, as long as it gains strong momentum and closes above the midpoint. Many imperfect piercing line patterns with this kind of open still reversed the downtrend when a volume spike came with the second candle.
The pattern is most reliable on the daily chart and weekly chart. Lower timeframes such as the 15-minute and hourly charts carry more market noise, so the same two-candle shape fails more often there.
How Does the Piercing Line Pattern Work?
The piercing line pattern shows a shift from selling pressure to buying pressure across two sessions. Each candle tells you what sellers and buyers did.
During the first candle, sellers stay in control and push price to a long bearish close that fits the existing downtrend. When the second candle opens lower, the downtrend looks set to continue and more sellers join in.
Buyers then step in near the lows and drive price back up through the session. A close above the midpoint means buyers recovered more than half of the first candle's losses, which suggests selling pressure is fading and price may have reached a support level.
The second candle still closes below the first candle's open, so buyers have not fully taken over. For this reason traders treat the piercing line as an early warning of a reversal and look for confirmation before buying.
How to Confirm a Bullish Piercing Pattern?
The piercing line pattern is a potential signal only. Traded alone, it gives more false signals, so traders look for confirmation from one or more of the tools below. Each tool has its own full guide; this section covers how each one applies to the piercing line.
Piercing Line at a Key Support Level
A piercing line that forms at a key support or resistance level is stronger than one that forms away from any key level. When the second candle bounces from a key level where buyers stepped in before, the key level and the pattern point to the same reversal.
Check for a key support/resistance level above the pattern as well. Resistance or a downward trendline close to the second candle can stop the rally, so conservative traders wait for a candle to close above it and treat that breakout as the buy trigger.
Piercing Line with RSI Divergence
The Relative Strength Index (RSI) adds weight when it shows bullish divergence. Bullish divergence happens when price makes a lower low while RSI makes a higher low, which shows selling pressure weakening even as price falls.
A piercing line that forms together with bullish divergence gives two separate signs that the downtrend is losing strength. Many traders see this pairing as one of the more reliable confirmations for the pattern.
Piercing Line with a MACD Crossover
The Moving Average Convergence Divergence (MACD) confirms the pattern with a bullish crossover, when the MACD line crosses above the signal line. At the very least, the two lines should start moving closer together as the piercing line forms.
MACD is built from moving averages, so the crossover often arrives a few candles after the pattern. Waiting for it cuts false signals, although part of the reversal may already be gone by the time you enter.
Piercing Line with Moving Averages
A short moving average, such as the 9-period exponential moving average (EMA), often acts as resistance during a downtrend. A close above that moving average after the piercing line forms shows buyers have pushed through a level that held the downtrend in place.
Match the moving average to your timeframe. The 9 and 20 EMA suit short-term trades, while the 50 and 100 period moving averages suit longer-term trades.
Piercing Line with Volume
Higher volume on the second candle shows real buying interest behind the reversal. A common guide is a volume spike of at least twice the average volume of the past month.
Spot forex has no central exchange, so forex charts show tick volume, which counts price changes during the candle. Tick volume still works for comparison: a second candle with clearly higher tick volume than recent candles adds weight to the pattern.
How to Trade the Piercing Line Pattern?
Once the piercing line pattern is confirmed, the trade plan comes down to three levels: entry, stop loss and take profit. The rules below follow the most common approach for this pattern.
Where to Enter a Piercing Line Trade
The standard entry is a buy stop order a few pips above the high of the second candle. Price has to trade above the whole pattern before the order fills, which filters out patterns that fail straight away.
A more conservative entry waits for a breakout above the nearest resistance or downward trendline. This entry comes later and usually at a higher price, and it only fills once the reversal has more evidence behind it.
Buy stop orders can fill with slippage when price moves fast through the order level, so the actual entry may sit a few pips above the planned price.
Stop Loss for a Piercing Line Trade
Place the stop loss a few pips below the low of the second candle. Because the second candle opens lower and then rallies, its low is usually the lowest point of the whole pattern.
A close back below that low means the buyers who formed the pattern have lost control, and the downtrend is likely to continue.
Take Profit for a Piercing Line Trade
Set the take profit just below the nearest key level above the entry, such as a previous support level that may now act as resistance. Aim for a risk reward ratio of at least 1:1, and set both levels from the chart without stretching the take profit to improve the ratio.
Piercing Candlestick Pattern Example on EUR/USD
This example shows how a trader could read and trade a piercing line pattern on the EUR/USD daily chart.
EUR/USD had been in a downtrend, making lower highs and lower lows. A long bearish candle printed, and the next candle formed the piercing line with these prices.
The second candle opened at 1.15800 and dipped to 1.15759 as sellers pushed price lower. Buyers then took over and drove price up to close at 1.16274, clearly above the midpoint of the first candle's body and still below its open.
Suppose tick volume on the second candle was clearly higher than on recent candles and RSI showed bullish divergence. With the pattern confirmed, the trader sets the trade levels below for a $10,000 account that risks 1% per trade.
A 1% risk limit on $10,000 is $100. At about $10 per pip for one standard lot of EUR/USD, a 66-pip stop loss gives a position size of about 0.15 lots.
If EUR/USD falls back below 1.15759 before reaching the take profit, the stop loss at 1.15740 closes the trade for a loss of about $100, plus any slippage. Holding the trade for several days also adds overnight swap charges or credits, which change the final result.
What Are the Advantages and Disadvantages of the Piercing Line Pattern?
The piercing line pattern is useful for spotting reversals early, but it has limits every trader should know before using it.
Advantages of the Piercing Line Pattern
Shows a clear shift in sentiment. Sellers control the first candle and buyers take over during the second candle, which gives traders an early sign that the downtrend may be ending.
Stronger than many two-candle reversal patterns. The second candle recovers more than half of the first candle's body, so it shows more buying pressure than a pattern such as the bullish harami, where the second candle stays inside the first.
Clear trade levels. The high and low of the second candle give an entry and a stop loss that are easy to set before placing an order.
Disadvantages of the Piercing Line Pattern
Not every piercing line is equal. A second candle that closes just above the midpoint is weaker than one that closes near 80% of the first candle's body, yet both pass the basic rule.
Needs confirmation. Traded alone, the pattern gives more false signals, and some patterns lead to a sideways market or a continuation of the downtrend.
Wide stop loss. The second candle is often long, so the distance from entry to stop loss is large. This can weaken the risk-reward ratio compared with patterns that have a smaller second candle.
Rare textbook gaps in forex. Without the gap down seen on stock charts, forex traders depend more on the midpoint close, volume and key levels to judge the signal.
Piercing Line vs Dark Cloud Cover
The dark cloud cover is the bearish mirror image of the piercing line pattern. There is no separate bearish piercing pattern, and traders searching for one are usually looking for the dark cloud cover.
The piercing line forms at the end of a downtrend and signals a possible bullish reversal. The dark cloud cover forms at the end of an uptrend, with a long bullish candle followed by a bearish candle that opens higher and closes below the midpoint of the first candle's body.
The same rules apply to both patterns in reverse, including the need for confirmation and the weaker signal when the second candle only just passes the midpoint.
Piercing Line vs Bullish Engulfing Pattern
The piercing line and the bullish engulfing pattern both start with a bearish candle and end with a bullish candle after a downtrend. They differ in how far the second candle closes.
In a piercing line, the second candle closes between the midpoint and the open of the first candle. In a bullish engulfing pattern, the second candle's body covers the whole body of the first candle and closes above its open.
The bullish engulfing pattern recovers all of the first candle's losses and adds new gains, so traders generally see it as the stronger bullish signal. If a second candle closes above the first candle's open, label it a bullish engulfing pattern and follow that pattern's rules.
What Mistakes Should You Avoid When Trading the Piercing Line?
Trading it outside a downtrend. A piercing line shape in an uptrend or a sideways market is unreliable, because there is no downtrend for it to reverse.
Measuring the midpoint on the full range. The midpoint comes from the first candle's body only. Adding the wicks moves the midpoint and can make a weak second candle look valid.
Buying before the second candle closes. The pattern only exists once the second candle closes above the midpoint, and price can fall back below it late in the session.
Skipping confirmation. Entering on the pattern alone, without a key level, bullish divergence or a volume spike, increases the number of false signals.
Poor position sizing. The wide stop loss on this pattern means a fixed lot size can risk far more than planned. Size each position from the stop loss distance.
FAQs
Is the Piercing Line Pattern Bullish or Bearish?
The piercing line pattern is bullish. It signals a possible reversal from a downtrend to an uptrend, and its bearish equivalent is the dark cloud cover, which forms at the end of an uptrend.
What Is the Best Timeframe for the Piercing Line Candlestick?
The daily chart and weekly chart give the most reliable piercing line signals. These timeframes reflect how most traders react to major news, while hourly and minute charts carry more noise and rarely show a gap down.
How Reliable Is the Piercing Line Pattern?
The piercing line pattern is more reliable after a long downtrend, at a key level and with confirmation from RSI, MACD or volume. A deeper close into the first candle's body adds to its reliability, although no candlestick pattern works every time.
