The first time I opened a candlestick chart I closed it in about four seconds. It looked like a heart monitor attached to something in distress. What finally made charts click for me was realizing a chart is not a prediction machine. It is a record of an argument between buyers and sellers, and it is only ever answering three questions.
- What is the price now, and what path did it take to get here?
- Is this move big or small for this particular stock?
- How many people were involved in the move?
Everything else — patterns, indicators, trendlines — is a variation on those three. Let's read a chart properly.
The axes, and the one setting beginners get wrong
The vertical axis is price per share. The horizontal axis is time. The setting that quietly misleads people is the range selector.
Pull up AAPL and flip between 1D, 1M, and 1Y. Same company, three different stories: a stock can be down 1.2% today, up 6% on the month, and down 14% on the year, all at once. All three are true. If you only ever look at one range, you are not analyzing — you are being framed by a default setting.
The second setting is linear vs log scale. On a log chart, $10 → $20 takes the same vertical space as $100 → $200, because both are +100%. For long-term charts log is more honest; for your first year, leave it linear and just be aware the option exists.
Reading a candle in ten seconds
Each candle covers one slice of time. It shows four numbers:
- Open — price at the start of the period
- Close — price at the end
- High / low — the extremes, drawn as the thin wick
Green (or hollow) means the close was above the open. Red means below. The body is the argument that was settled; the wick is the argument that was rejected. A candle with a long lower wick means sellers pushed the price down hard and buyers pushed it all the way back — that is a genuinely different event from a small red candle, even if both end the day down.
If candles feel like too much on day one, switch the chart to the mountain view. You lose the open/high/low detail but the trend is easier to see, and trend is what matters first.
Volume: the part beginners ignore and professionals check first
Volume is the bar chart underneath. It counts shares traded.
Here is the rule that took me a year to internalize: a price move without volume is a rumor; a price move with volume is a decision.
Worked example. A stock trades an average of 4 million shares a day and closes up 5%:
- If that day's volume was 3.1 million — below average — the move was thin. A handful of buyers pushed a quiet tape. It very often gives the move back.
- If volume was 19 million — nearly 5× normal — something happened. Earnings, an upgrade, a product announcement, index inclusion. Institutions moved size.
Same 5% on the chart. Completely different meaning. When I see a big move now, I look at the volume bar before I read a single headline.
Working through a real move, line by line
Say you open NVDA and see this on the daily chart:
| What you see | What it tells you |
|---|---|
| Price gapped up from $178 to $191 at the open | Something happened outside market hours — news, earnings, or guidance |
| Volume bar is 3× the neighbouring bars | Real participation, not drift |
| The candle has a long upper wick, closing at $184 | Buyers pushed to $193 and got sold into; the enthusiasm faded intraday |
| The next two candles are small and red on low volume | Digestion, not reversal — few people are trading it |
Reading that in sequence gives you an actual narrative: good news, strong initial buying, profit-taking into the strength, then a quiet pause. You did not need a single indicator.
Then you do the part most chart tutorials leave out: you go find out what the news was. Open the stock page and read the plain-English explanation of the move, or check the Market Brief for that day. A chart tells you that something happened and how much conviction was behind it. It never tells you what.
Support and resistance, without the mysticism
Support is a price area where buyers have repeatedly shown up. Resistance is where sellers have. They exist because they are where people made decisions — a stock that stalled three times at $250 has a lot of holders who bought at $250 and want to get out even.
Two honest caveats:
- They are zones, not lines. $248–$252, not exactly $250.
- The more times a level is tested, the weaker it usually becomes, not stronger. Each test consumes the orders sitting there.
Draw them with a flat horizontal line on a weekly chart, using closing prices rather than wicks. If you need seven trendlines to see a pattern, the pattern is not there.
The five mistakes I see constantly
- Reading a 1D chart as if it were a company's story. Today's 2% move is noise on the scale of your holding period.
- Ignoring volume entirely. It is the confirmation layer for everything else.
- Confusing a low share price with a cheap company. A $6 stock is not on sale.
- Finding patterns after the fact. Everything looks like a head-and-shoulders once you know the outcome. Mark your level *before* the move, not after.
- Trading a chart with no idea what the company does. A chart is one input. Picking a first stock covers the other half.
Practice, cheaply
Pick three names — one index ETF like SPY, one steady large-cap like MSFT, one volatile one like NVDA — and add them to your watchlist. Every day for two weeks, look at each chart for 60 seconds and write one sentence: what happened, and was volume above or below average. Fourteen days of that will teach you more than any pattern list.
