A candle is a whole session's fight, drawn in one mark. Learn to read it.
The candlestick is the most information-dense mark in all of trading. In one small shape it tells you where a session opened, where it closed, and the highest and lowest anyone was willing to pay in between — the whole tug-of-war between buyers and sellers, at a glance. Learn to read the body and the wicks and you can feel the balance of a market shifting before any indicator catches up. You don't need fifty patterns. You need the anatomy, and the four or five candles that actually say something.
Every candle is built from four prices: the open, the close, the high, and the low of its session — a day, an hour, five minutes, whatever timeframe you're on. The thick part, the body, runs between the open and the close; the thin lines, the wicks, reach out to the high and the low. Colour tells you who won: a green body means the close finished above the open — buyers carried the session; a red body means sellers did. That's the whole grammar. Everything else is just learning to read what the size and shape are telling you.
The size of the body is conviction. A long body means one side dominated from open to close — a decisive session. A short body means the two sides fought to a draw. The wicks mark where price went but couldn't stay. A long lower wick says sellers drove price down hard and buyers slammed it back up — rejection of lower prices. A long upper wick says the reverse. So a small body with long wicks on both ends is a market full of noise and no resolution, while a long body with tiny wicks is a market that made up its mind. Read those two things — body and wicks — and you're already ahead of most people staring at the same chart.
When the open and close land at almost exactly the same price, the body shrinks to a thin line and you get a doji — the purest picture of indecision. Buyers and sellers pushed all session and ended right back where they started. On its own, mid-range, a doji is just noise. But a doji at the top of a long rally, or the bottom of a hard sell-off, is worth your attention: it says the trend that got you here has suddenly run out of agreement. It's not a signal to act — it's a signal to watch, because the balance that drove the move just wobbled.
These two are the same idea pointed in opposite directions, and they're among the most useful single candles on the chart. A hammer has a small body up top and a long lower wick — price got driven down hard, then buyers stepped in and hauled it all the way back. At the bottom of a decline, it says sellers tried to push lower and failed. A shooting star is the mirror image: a small body with a long upper wick, showing buyers reached higher and got rejected. At the top of a rally, it warns the buying is exhausted. In both, the long wick is the whole message — it marks the price the market refused.
The strongest single-bar signals involve two candles. A bullish engulfing is a big green candle whose body completely swallows the prior red one — in a single session, buyers didn't just win, they erased the sellers' last move entirely. At the bottom of a decline, that's a loud shift in control. A bearish engulfing is the reverse: a big red body engulfing the prior green one at the top of a rally. Engulfing patterns matter because they show decisive reversal, not a quiet one — the new side took over so forcefully it undid the old side's work. Like every candle signal, it means far more at a level or the end of a trend than floating in the middle of nowhere.
Candlestick patterns are probabilities, not promises — and they mean almost nothing without context. A hammer mid-range is just a candle; a hammer at support after a long decline is a setup. Never trade a single candle in isolation: it needs a where (a level, the end of a trend) and ideally a confirmation — the next candle following through. The traders who lose with candlesticks see a shape and click; the ones who win wait for the shape to appear in the right place.
