Anatomy of a single candlestick

A candlestick plots four prices from a single trading session — open, high, low and close — in one compact shape. The rectangular body spans the open-to-close range. Thin lines called wicks (or shadows) extend from the body to the session high above and the session low below.

Colour carries the most immediate signal: a green body means the session closed above where it opened (bulls won); a red body means it closed below (bears won). The size of the body shows conviction — a long green body after a prolonged downtrend is far more meaningful than a tiny one in the middle of a range.

What wicks reveal

Wicks are often more informative than the body. A long lower wick means sellers drove price down during the session but buyers pushed it back up before the close — a sign of buying demand at lower levels. A long upper wick is the opposite: buyers attempted a rally but sellers absorbed the move and forced price back down.

When you see a candle whose wick is two to three times the length of its body, the market is telling you about a significant rejection at that price level. That level often becomes an important reference point for subsequent sessions.

Key single-candle patterns

Four single-candle formations carry strong signal value:

• Doji — open and close are virtually the same, leaving only wicks. It signals indecision and is most meaningful after a strong trend. A doji at a resistance level after an uptrend warns of a potential reversal.
• Hammer — small body near the top, long lower wick. Appears after a downtrend and signals that sellers attempted to drive price lower but buyers rejected the move. Bullish reversal signal.
• Shooting Star — the mirror image of a hammer. Small body near the bottom, long upper wick. Appears after an uptrend; bearish reversal signal.
• Marubozu — a full body with virtually no wicks. A green marubozu (opened at low, closed at high) reflects overwhelming buying pressure. A red marubozu reflects overwhelming selling.

Key two-candle and three-candle patterns

Multi-candle patterns add context that a single candle cannot provide:

• Bullish Engulfing — a small red candle followed by a large green candle whose body completely engulfs the prior red candle. A classic reversal signal at support.
• Bearish Engulfing — the opposite: a large red candle engulfs a prior small green candle at a resistance level.
• Morning Star (three candles) — a large red candle, a small-bodied candle (gap or doji), then a large green candle. Strong bullish reversal, especially after a prolonged downtrend.
• Evening Star — the bearish counterpart to the morning star. Signals exhaustion at the top of an uptrend.

A worked NIFTY example

Consider a hypothetical scenario where NIFTY has been falling for three sessions and is approaching the 22,000 level — a zone where the option chain shows heavy put open interest (a support signal). On the daily chart, a hammer candle forms: NIFTY opens near 22,050, dips to 21,850 during the session, but closes back at 22,030. The long lower wick of 180 points tells you sellers tried to break below 22,000 but were overwhelmed by buyers.

Next session NIFTY opens flat and closes above 22,200 on above-average volume — a confirming green candle. Together, the hammer plus confirmation candle form a classic two-session reversal setup. A positional trader might consider a long NIFTY 22,000 CE (with lot size 75) with a stop below the hammer's low of 21,850 — a defined risk of roughly 180 points x 75 = ₹13,500 per lot.

Combining candlesticks with other tools

Candlestick patterns should never be used in isolation. Their power multiplies when they:

• Form at identified support and resistance levels
• Are confirmed by rising volume or increasing open interest in the direction of the signal
• Align with a moving average acting as dynamic support or resistance
• Occur when the RSI is at an extreme (oversold for bullish patterns, overbought for bearish)

Common mistakes to avoid

• Acting on a pattern before it closes. A candle only "confirms" once the session closes. An apparent hammer can turn into a long red candle if selling resumes before market close at 3:30 PM IST.
• Ignoring the trend. A bullish engulfing in a strong downtrend is a counter-trend trade — lower probability than the same pattern at the end of a well-established decline.
• Using patterns on illiquid instruments. On NSE, stick to liquid stocks and the main indices. Thin-volume instruments produce unreliable patterns because a single large order can paint a misleading candle.
• Treating every doji as a reversal. Dojis during sideways consolidation are routine — they carry weight only after a strong directional move.

Frequently asked questions

What does a candlestick's body represent?

The body is drawn between the open and close prices. A green body means the close was above the open (buyers dominated); a red body means the close was below the open (sellers dominated). Body size reflects conviction — a large body signals a decisive session.

What do upper and lower wicks tell you?

Wicks show the extremes reached during the session that were not sustained at close. A long lower wick signals buyer demand below the body; a long upper wick signals seller supply above the body. Both represent price rejection at those levels.

How reliable are candlestick patterns on Indian indices?

Patterns on NIFTY 50 and Bank Nifty are considered more reliable than on individual stocks due to high institutional participation. That said, no pattern is a standalone signal — always confirm with volume, open interest and key price levels.

Which timeframe should a beginner use?

Start with the daily chart to understand the primary trend, then use 15-minute or 1-hour charts for entry signals. Intraday NIFTY traders commonly watch the 5-minute chart for entries while using the 15-minute for context. Higher-timeframe patterns carry more weight.
