Anatomy of a Candlestick

If price is a fight, where's the scoreboard? Meet the candlestick: the alphabet of every chart you'll ever open. Today: just the parts, one at a time.

Recalls · 2.3 Technical Analysis ~3 min 1 game + quiz
Press play. We build one candle, four prices at a time.
⏲ Parked for Lesson 2.5: who WON the candle. Today is parts only.
Build 1 of 4

The open: the starting whistle

A candle covers one chunk of time, say one day. Four prices from that day get packed into one shape. First price in: the open, the price when the day started.

The open · day starts
$50.00

Our example stock opens the day at fifty dollars. Mark it on the scale. That single tick is the open. One number, nothing else yet.

Buyers and sellers in a tug-of-war over a price
Recall 2.2: every price is a tug-of-war. A candle is one round of that fight, written down.

The close & the body

Second price: the close, where the day ended. Fill in the stretch between open and close and you get the candle's solid block: the body.

Open
$50.00
Close
$54.00

Open at fifty, close at fifty-four. Colour in that stretch. That block is the body. The body is always the open-to-close range, nothing more.

Two prices in, and you've already got the fat part of the candle.

The wicks: how far the fight swung

Price doesn't walk a straight line from open to close. It wanders. The high and the low get drawn as thin lines poking out of the body: the wicks.

High · top of upper wick
$55.00
Low · tip of lower wick
$49.00

Spiked to fifty-five, dipped to forty-nine. Body = open-to-close. Wicks = the full range price traveled.

Wicks record the full journey: every push beyond the body that didn't hold to the close.
Build 4 of 4 · Worked Example

Four numbers, one shape

Open 50 · Close 54 · High 55 · Low 49. Watch the whole candle assemble. This exact shape is what a chart is made of, over and over.

Open
$50
Close
$54
High
$55
Low
$49
The block in the middle is the body; the two threads are the wicks. That's the entire skeleton.

Quick check

Four questions. Show me the parts.

1. The BODY of a candlestick always shows the range between:

The body is the open-to-close range, nothing more. The high and the low belong to the wicks.

2. The thin lines poking out of the body are called wicks. What do they mark?

The upper wick reaches to the high, the lower wick to the low: the full range price traveled.

3. A stock opens at $20, closes at $23, touches $24 and $19. Where does the body sit?

Body = open ($20) to close ($23). The $24 high and $19 low are the wick tips.

4. How many prices does one candlestick pack into one shape?

Four numbers, one shape: open, close, high, low. Body plus two wicks.
0 / 4

Recap

You've got the alphabet

A candlestick is four prices in one shape: open, close, high, low.

The body is the open-to-close range: the fat block.

The wicks reach to the high and the low: the full journey.

We did NOT read who won yet. That's deliberate, and it's next.
