How to Read Candlestick Charts: A Beginner’s Guide

TL;DR:A candlestick encodes four prices (open, high, low, and close) in a single shape, with the body showing the open-to-close range and the wicks marking the extremes reached along the way. Individual patterns like dojis or engulfing candles mean far more next to real support, resistance, or volume than they do on their own.

A candlestick chart looks intimidating the first time you see one, rows of little coloured blocks with lines sticking out of them. Once you know what each part represents, though, it stops looking like noise and starts looking like a compressed summary of exactly what happened during that period.

The Four Numbers Behind Every Candle

Every candle, whether it represents one minute or one day, encodes four prices: the open (where price started), the high (the highest point reached), the low (the lowest point reached), and the close (where price ended). The thick part of the candle, called the body, spans from the open to the close. The thin lines above and below, called wicks or shadows, mark the high and low.

Why Colour Matters

When the close is higher than the open, the candle is usually shown in one colour (commonly green, or sometimes hollow) to mark a bullish period. When the close is lower than the open, it’s shown in another colour (commonly red, or filled) to mark a bearish one. The exact colours vary by platform and can be changed in settings, but the underlying logic never does: colour tells you which direction won that period, not by how much.

What the Wick Length Actually Tells You

A long wick means price travelled to that extreme and got pushed back before the period closed, a rejection. A long upper wick suggests sellers stepped in near the highs; a long lower wick suggests buyers stepped in near the lows. A candle with almost no wick at all, where the close sits near the high or low, suggests one side was in control for the whole period with little pushback.

A Few Patterns Worth Knowing, Not Memorizing

• Doji: open and close are nearly equal, signalling indecision rather than a clear winner for that period
• Engulfing: a candle whose body fully covers the previous candle’s body, often read as an early reversal signal
• Hammer / shooting star: a small body with a long wick on one side, suggesting a rejection at an extreme after a move in one direction

Timeframe Changes What a Candle Actually Represents

The exact same candle shape means something different depending on the timeframe it’s drawn on. A long-wicked rejection candle on a 5-minute chart reflects a few minutes of order flow and can be noise. The same shape on a daily or weekly chart reflects an entire session or week of activity, and tends to carry far more weight as a signal. Reading candlestick patterns without paying attention to the timeframe they’re formed on is one of the more common ways beginners misjudge how significant a pattern actually is.

A useful habit is checking a pattern across at least two timeframes before treating it as meaningful: a daily candle that looks decisive should generally line up with something sensible happening on an hourly chart underneath it, not contradict it entirely.

None of these patterns work as a signal in isolation. They’re context clues that mean far more next to a real support or resistance level, or alongside volume, than they do floating on their own in the middle of a chart.
