Reading a candlestick chart
Why this lesson exists
Every chart you'll ever look at on xtree is a candlestick chart. Every Pattern Lab session you'll attempt is a sequence of candles. If candles are still slightly fuzzy to you — what the wick represents, how a 1h candle relates to a 15m candle, why a doji at support is interesting — you're guessing at every setup.
This lesson is the prerequisite for the entire Pattern Lab and for Module 3. It's short and largely visual. By the end you'll read a candle the way you read a sentence: instantly, without thinking about it.
What a candle encodes: OHLC
Every candle is a compressed picture of four numbers over a fixed time window:
- Open: the price at which the candle started.
- High: the highest price traded during the window.
- Low: the lowest price traded during the window.
- Close: the price at which the candle ended (and the next one starts).
The body of the candle is drawn between open and close. The wicks (thin lines, sometimes called "shadows") extend from the body to the high and the low.
Bullish candle: close > open. The body is typically rendered green or hollow. The body's bottom edge is the open; the top edge is the close.
Bearish candle: close < open. The body is typically red or filled. The body's top edge is the open; the bottom edge is the close.
That's the whole encoding. Four numbers, two colours, two wicks. Everything else is interpretation.
What the body tells you
The body of a candle is the net result of the window: where buyers and sellers ended up agreeing.
A long body in either direction is a strong directional close. Buyers (or sellers) controlled the period from open to close. Pullbacks during the window were short and didn't change the verdict.
A short body — open and close close together — is indecision. Whatever fighting happened intra-candle, the period closed roughly where it started. Neither side won.
The clearest example is the marubozu: a candle with a long body and almost no wicks. The 1-hour BTC candle from 14:00–15:00 UTC on 2024-02-28 was a textbook one: opened around $60,500, closed near $62,800, with negligible wick on either side. The market spent the entire hour in one-sided buying — no pullback to a wick. The next four candles continued upward, which is what a marubozu in a trending market usually signals.
What the wicks tell you
Wicks are where price went and then came back from. They're the visible footprint of a battle that didn't hold.
Long upper wick, small body: price pushed up during the window but sellers absorbed it before close. The market rejected higher prices. If this happens at a known resistance level, it's a high-conviction rejection.
The 1-hour BTC candle at 04:00 UTC on 2024-03-14 is the canonical example. It opened around $73,300, spiked to a high of $73,777, and closed near $71,200 — a long upper wick of about $2,500. That wick marked the local top. BTC didn't see $73,777 again until late October 2024.
Long lower wick, small body: the inverse. Price was pushed down during the window but buyers absorbed it before close. Demand showed up at the lows.
Wicks on both sides, small body: the candle is telling you the market had two unsuccessful attempts in opposite directions and ended up roughly where it started. Read this as indecision in a known context — at support, it might suggest a reversal; in the middle of a trend, it's just noise.
The doji and its context
A doji is an extreme case: open and close are at (or nearly at) the same price. The candle looks like a cross or a plus sign with thin wicks above and below.
A doji alone tells you nothing. A doji in context can tell you a lot.
- A doji at the top of an extended uptrend, after several long bullish bodies: indecision after a one-sided move. Often a precursor to a reversal.
- A doji at a major support level after a multi-day decline: indecision after relentless selling. The 2022-11-21 daily candle around $15,500–$15,800 was a doji that marked the cycle low after the FTX collapse. BTC never traded below $15,480 again.
- A doji in the middle of a range, far from any level: meaningless. Just a candle.
The lesson: candles are signals; signals need context. Pattern Lab will repeatedly show you the same candle shape with two different contexts and two different outcomes. That's the whole point.
Timeframes and the fractal nature of price
A 1-hour chart is built from twelve 5-minute candles, or four 15-minute candles, or sixty 1-minute candles. Same price action, different aggregation.
The choice of timeframe determines what you see and what you miss.
| Timeframe | Best for | Trade-off | |---|---|---| | 1m / 5m | Scalp entries, precision timing on confirmed setups | Mostly noise; signal-to-noise ratio is brutal | | 15m | Intraday entries with some context | Good for fast swing trades; misses larger trend | | 1h | The workhorse for most retail discretionary trades | Slow enough to think; fast enough to act intraday | | 4h | Trend identification, swing entry timing | Multi-day patience required | | 1D | Macro structure, multi-week swing planning | Few signals per month |
A useful habit: pick a "trading timeframe" (where you decide on entries) and a "context timeframe" one or two steps higher (where you check the bigger picture). If you trade the 15m, look at the 1h before every entry. If you trade the 1h, look at the 4h. This is how you avoid taking trend-against trades because the smaller timeframe looked good in isolation.
What candles don't tell you
This is the most underrated part of candle literacy. Candles compress a window of price action into four numbers — and lose information in the process.
A clean red 1-hour candle on 2024-08-05 during the yen-carry crash looked like normal trending downside. What the candle didn't show: $1.14 billion of leveraged longs were being liquidated into the candle, and bid liquidity below ~$49,000 was paper-thin. A trader reading only the candle might have shorted into the bottom. A trader who also checked the orderbook (see reading the orderbook) would have seen the vacuum and waited.
Candles don't show:
- Volume context. Was this candle on 5× normal volume or 0.2× normal volume? The body looks the same but the meaning is opposite.
- Order book depth. The candle closed at ₹85,00,000 — is that price defended by ₹50L of bids below, or is the next bid ₹40,000 lower?
- What happened inside the candle. Two candles can have the same OHLC but completely different paths. One straight up, one a wild whipsaw — same body, very different to trade in real time.
Treat candles as one layer. The orderbook is the other. Together they're a much sharper picture than either alone.
Worked example: same candle, two contexts
A long upper wick on a 1h BTC candle: open ₹85,00,000, high ₹85,80,000, close ₹85,10,000, low ₹84,90,000.
Context A: BTC has been ranging between ₹84,50,000 and ₹85,50,000 for two days. ₹85,80,000 is the high of a tested resistance level. The wick is a third rejection of that level. Read: bearish, range likely to hold, fade the next push toward resistance.
Context B: BTC has been in a clean 1-hour uptrend for three days, making higher highs and higher lows. ₹85,80,000 is a new local high. The wick is the first sign of slowing momentum. Read: cautious — the trend isn't broken (the candle still closed above the previous close), but pile-on long entries here have worse R:R than a few hours ago. Wait for a pullback to a 20-EMA touch instead.
Same candle, opposite trades. The shape is necessary but not sufficient — context is what makes it actionable.
Common misunderstanding
"A bullish candle means the price is going up next."
No. A bullish candle means the price went up during the candle's window — which is in the past. What happens next depends on the higher-timeframe context, the level the candle closed at, the volume, and the orderbook. A bullish candle into a known resistance with declining volume often resolves down. A bearish candle bouncing off support with strong volume often resolves up.
Candles are descriptions of the recent past, not predictions of the next bar. The Pattern Lab exists precisely to train this distinction — show the trader the candle, ask them what comes next, and show them what actually happened. The wrong answers in that exercise are almost always the trader treating the candle shape as a forecast rather than a signal that needs context.
Recap
- Every candle encodes OHLC: open, high, low, close. The body is open-to-close; the wicks are the extremes.
- Bodies tell you who won the window; wicks tell you what was attempted and rejected.
- Doji is indecision — meaningful at extremes, noise in the middle.
- Timeframes are aggregations of the same price action. Pick a trading timeframe and a context timeframe one step higher.
- Candles don't show volume, depth, or intra-candle path. Combine with the orderbook for a full picture.
Up next, you have a choice depending on your interest. If you want to start practising what you've learned: head to the Pattern Lab. If you want to build risk discipline before practising, go to position sizing. Either is a fine next step — Module 1 has given you the vocabulary; Module 2 gives you the survival rules.
