A candlestick is a visual representation of price movement over a specific time period — one minute, one day, one week. Each candle carries four data points: the opening price, the highest price reached, the lowest price reached, and the closing price.
Before reading patterns, a trader needs to understand what a single candle is actually telling them.
The Anatomy of a Candlestick
The rectangular body of a candle represents the distance between open and close:
- Green (or white) body — Price closed higher than it opened. Buyers were in control for that period.
- Red (or black) body — Price closed lower than it opened. Sellers were in control.
The thin lines extending above and below the body are called wicks (or shadows):
- Upper wick — The highest price reached during the period, before sellers pushed it back down.
- Lower wick — The lowest price reached during the period, before buyers pushed it back up.
A long upper wick tells you that buyers pushed the price up, but sellers rejected that move and drove it back down before the candle closed. This is a sign of selling pressure at that level — even if the candle itself closed green.
Four Patterns Worth Knowing on NSE
1. The Doji
A doji has a very small body — the open and close are nearly the same price. The wicks can extend in either direction.
A doji signals indecision. Neither buyers nor sellers dominated. Seen after a strong trend, it can indicate that momentum is fading. Context matters: a doji at a known resistance level after a five-day rally carries more information than a doji in the middle of sideways price action.
2. The Hammer
A hammer has a small body near the top of the candle and a long lower wick — typically at least twice the length of the body. It forms when sellers push the price down during the session, but buyers recover most of that ground before the close.
Found at the bottom of a downtrend or at a known support level, a hammer suggests that selling pressure is being absorbed. It is not a buy signal by itself — it is a question: is buying pressure strong enough to reverse the trend?
3. The Bullish Engulfing
A bullish engulfing pattern spans two candles. The first candle is red (sellers in control). The second candle is green and its body entirely covers — engulfs — the first candle's body.
This shows a shift in momentum: the selling from the previous session was fully overcome by buying in the current session. Seen with above-average volume, it carries more weight.
4. The Shooting Star
A shooting star has a small body near the bottom of the candle and a long upper wick. It is the inverse of the hammer. Sellers rejected a price push upward and drove the price back down before the close.
Found at resistance levels or at the top of a rally, it signals potential reversal — but again, context and volume are required to evaluate it properly.
Reading Volume Alongside Candlesticks
A candlestick pattern without volume context is incomplete information. In Indian markets on NSE:
- A hammer forming on higher-than-average volume suggests more genuine buying absorption.
- A bullish engulfing on very low volume may just be a low-participation day, not a real shift in control.
- A shooting star on extremely high volume — especially in a liquid large-cap — tells a clearer story than the same pattern on thin trading activity.
The NSE market depth screen (available in Zerodha Kite and most trading platforms) shows real-time bid and ask volumes. Watching how price and volume interact at key levels — not just the candle shape — is what separates mechanical pattern-matching from genuine price reading.
What to Avoid
The most common mistake is treating candlestick patterns as signals in isolation. A hammer on an illiquid small-cap stock that has no real support level, formed after a news-driven spike, is not the same as a hammer on a liquid Nifty 50 constituent at a level where price has reversed three times in the past twelve months.
The pattern is the same. The context — the price structure around it and the volume behind it — is what gives it meaning.
