How to read a single candle
One bar on a chart is a candle. A single candle compresses everything that happened in a fixed slice of time into four numbers.
The four numbers
- Open — the price when that slice started
- Close — the price when it ended
- High — the highest price inside it
- Low — the lowest
Body and wick
The thick part between open and close is the body. The thin lines poking out above and below are wicks.
- Close above open is an up candle
- Close below open is a down candle
A long body means the start and end prices were far apart. A long wick means price went that far and came back.
What a wick tells you
A long lower wick means price fell that far and returned before the slice ended. Someone bought down there — that is the trace they left.
A long upper wick is the mirror image: it went up and got pushed back.
The usual mistake
Never judge on one candle alone. The same shape means something completely different depending on where it sits. A long upper wick after a long climb and a long upper wick at the lows are two different stories.
