Assessing the strength, validity, and reliability of candlestick signals

Candlestick patterns offer a wealth of information for traders in technical analysis. However, beyond the basic understanding of candlestick shapes and patterns, several deeper principles help traders assess the strength, validity, and reliability of candlestick signals. In this write-up, we will explore several key concepts for interpreting candlestick patterns effectively.

The shadow (or wick) of a candlestick represents the range between the high and low prices during the trading session. A longer shadow indicates greater price movement outside the range of the candlestick’s open and close.

• Upper Shadow (Wick): A long upper shadow signifies that buyers attempted to push the price higher but were met with strong selling pressure, forcing the price back down before the close.

• Lower Shadow (Wick): A long lower shadow indicates that sellers pushed the price lower, but buyers stepped in and pushed the price back up before the close.

• Bullish Indication: A long lower shadow (with a small real body at the top) suggests that sellers lost control, and buyers are now in a better position to take control of the market.

• Bearish Indication: A long upper shadow (with a small real body at the bottom) indicates that buyers tried to push the price up but were overpowered by sellers, which may signal weakening bullish momentum.

• A long shadow represents market indecision and a possible turning point. The longer the shadow relative to the real body, the more significant the reversal potential. The shadow reflects a failure to sustain extreme price levels and signals that the opposing market force is gaining control.

• Traders can use long-shadowed candles, such as the Hammer (long lower shadow) and Shooting Star (long upper shadow), to identify potential reversals.

• The Hanging Man and Inverted Hammer also rely on long shadows for their effectiveness in signaling trend reversals.

Explanation:

The size of a candlestick compared to previous candles gives traders insight into the strength of price movements and the momentum behind a potential trend shift.

• Large Candlestick: A large candlestick (relative to the previous ones) signifies strong momentum, either bullish or bearish. It can indicate a breakout or a significant shift in sentiment.
• Small Candlestick: A small candlestick, especially following a series of large ones, may indicate a loss of momentum, indecision, or potential consolidation.
• 

• Small Candlestick: A small candlestick, especially following a series of large ones, may indicate a loss of momentum, indecision, or potential consolidation.

• Bullish Reversal: If a large bullish candlestick appears after a series of small bearish candles, it suggests that buying pressure is building up, and a trend reversal could occur.

• Bearish Reversal: Conversely, a large bearish candlestick after a series of small bullish candles indicates that selling pressure is increasing and that a downtrend may be imminent.

• A larger-than-average candlestick reflects strong conviction from market participants, whether buyers or sellers. It signals that a significant shift in sentiment has occurred, leading to a price move with strong momentum.

• Patterns like Engulfing (where the second candle completely engulfs the previous candle) and Three White Soldiers or Three Black Crows (where three large candles form consecutively) demonstrate this principle in action.

• Always compare the current candlestick to the preceding ones to judge whether the current movement has sufficient momentum for a sustainable reversal or trend continuation.

A gap occurs when the open of a candlestick is significantly higher or lower than the previous close, leaving a “gap” between the two candlesticks’ real bodies. Gaps represent strong momentum shifts.

• Gap Up: Indicates that buyers are so enthusiastic they are willing to pay a higher price, leading to a significant upward price gap. This can suggest strong bullish momentum.

• Gap Down: Indicates that sellers are eager to exit their positions, leading to a sharp decline in price. This shows strong bearish momentum.

• Bullish Gap: A bullish reversal signal is more reliable if the real body of the reversal candle gaps away from the previous candle’s real body, as this shows a clear shift in sentiment.

• Bearish Gap: Similarly, a bearish reversal signal is stronger when the reversal candlestick gaps below the previous candle’s real body, showing a sudden shift to bearish sentiment.

• Gaps occur because of a significant change in sentiment, usually due to external factors like news, earnings reports, or economic data. The gap represents an urgent shift in supply and demand, with either buyers or sellers overwhelming the other side of the market.

Application:

• Patterns such as the Morning Star or Evening Star (form of exhaustion gaps) are more reliable when the second or third candle opens with a gap, confirming the shift in market sentiment.

• Breakaway Gaps at the beginning of a new trend or exhaustion gaps at the end of a trend can serve as strong entry or exit signals.

The location of a reversal candlestick in the context of a trend is crucial. A steep trend — whether upward or downward — often signals that the market is becoming overbought or oversold, making a reversal more likely.

• Bullish Reversal at the Bottom: A reversal candle such as a Hammer or Bullish Engulfing becomes much more significant when it forms after a steep downtrend. This shows that selling momentum is exhausted, and buyers are stepping in to reverse the trend.

• Bearish Reversal at the Top: A reversal candle like a Shooting Star or Bearish Engulfing gains importance at the top of a steep uptrend, signaling that buying momentum is fading, and sellers are starting to take control.

•

• At Trend Extremes: Reversal patterns are more meaningful when they occur at the extreme of a trend. A long, steep uptrend or downtrend often means that the market has stretched too far, increasing the likelihood of a reversal.

• The market can only sustain steep trends for a limited time before reaching extreme price levels. Reversal candles at these points indicate exhaustion of the prevailing trend, where buyers (in an uptrend) or sellers (in a downtrend) are running out of momentum.

Application:

• Look for Shooting Stars or Bearish Engulfing patterns at the top of sharp uptrends for potential short-selling opportunities.

• Look for Hammers or Bullish Engulfing patterns at the bottom of steep downtrends to signal potential long entries.

The color of the candlestick’s real body (bullish or bearish) is less important than the overall structure of the candlestick. What matters most is the context, such as the length of the shadows, position in the trend, and relationship to surrounding candles.

• A long shadow or a significant candlestick pattern (e.g., Hammer, Engulfing) holds more significance than whether the real body is bullish (green) or bearish (red).

• Focus on Structure: For instance, a Hammer or Shooting Star can be bullish or bearish regardless of the real body’s color. The pattern reflects market indecision and a potential reversal, regardless of whether it is a red or green candlestick.

• Market Psychology: The structure of the candle — the size of the body relative to the shadows — tells us more about market sentiment than the candle’s color. The shift from one market sentiment to another (buying vs. selling pressure) is more important than whether the candle closes slightly above or below the open.

• When interpreting candlestick patterns like Hammers, Shooting Stars, or Doji, focus more on the length of the shadows and the position of the candlestick in the trend than on the color of the real body.

• For example, both red and green Doji candlesticks are indecision candles, signaling a possible reversal when confirmed by other technical factors.

A trendline breakout adds confirmation to a potential reversal indicated by a candlestick pattern. Trendlines represent the general direction of the market. When a reversal candlestick pattern forms, a trendline breakout provides confirmation that the trend has indeed reversed.

• Bullish Reversal: If a Bullish Engulfing or Doji pattern forms at the bottom of a downtrend, followed by a breakout above the downward trendline, this confirms that the downtrend is likely over, and a new uptrend is beginning.

• Bearish Reversal: Similarly, if a Bearish Engulfing pattern forms at the top of an uptrend and is followed by a breakdown below the upward trendline, it confirms that the uptrend has reversed.

• A candlestick reversal pattern alone may not always be enough to act on. Combining it with a trendline breakout helps filter out false signals and provides a stronger confirmation of a trend change.

• When the price breaks a trendline, it shows that the prevailing trend has lost its strength, and market participants are pushing the price in the opposite direction. A trendline breakout following a reversal pattern shows a decisive shift in sentiment.

• Combine reversal patterns like Engulfing, Harami, and Tweezer with a trendline breakout for higher probability trades. Only enter a trade once the price has confirmed the reversal by breaking through the trendline.

Reversal candlesticks are more reliable when they occur near key support or resistance levels. These levels act as barriers where price often reverses, so a candlestick pattern forming near such levels is more likely to result in a successful reversal.

• At Support: A bullish reversal candlestick pattern (e.g., Hammer or Bullish Engulfing) forming near a support level indicates that buyers are stepping in to defend the support, increasing the chances of a reversal.

• At Resistance: A bearish reversal candlestick pattern (e.g., Shooting Star or Bearish Engulfing) forming near a resistance level indicates that sellers are defending the resistance, suggesting the price may reverse downward.

• Stronger Signal at Key Levels: The closer a reversal pattern is to a significant support or resistance level, the more reliable the pattern becomes. Support and resistance levels act as decision points where traders are likely to buy or sell in large quantities.

Psychology:

• At key support or resistance levels, traders watch closely for signs of exhaustion or strength. A reversal candlestick pattern at these levels indicates that the prevailing trend is losing momentum, and traders should consider positioning for a reversal.

Application:

• Use support and resistance levels as reference points to determine the strength of a candlestick reversal pattern. Only act on reversal patterns when they occur at these important levels to increase the probability of success.

In summary, interpreting candlestick patterns effectively goes beyond simply identifying the shape of the candle. By considering factors like the length of the shadows, relative size of the candlestick, gaps between candles, the steepness of the trend, and the location of key support or resistance levels, traders can significantly improve their decision-making and the reliability of their signals. Combining candlestick analysis with trendline breakouts and levels of support or resistance allows traders to filter out false signals and confirm trend reversals with greater confidence.
