So, you’ve decided to stop guessing based on “vibes” and actually look at a price chart. Welcome to the big leagues. Understanding charts is the difference between being a “strategic investor” and someone who just likes clicking shiny buttons on an app.
Here is your professional—yet slightly cynical—guide to making sense of the squiggly lines.
1. The Line Chart: The “Minimalist” Approach
The line chart is the “I just want the highlights” version of data. It connects the closing prices over a set period, creating a smooth, clean line.
The Vibe: It’s like reading the summary on the back of a book instead of the whole novel.
Best For: Seeing long-term trends without getting a headache from the daily drama.
The Downside: It hides the “chaos.” You won’t see if the price plummeted and skyrocketed in the same day; you only see where it landed when the music stopped.
2. The Bar Chart: The “Overachiever”
If the line chart is a summary, the bar chart is the detailed report. Each vertical bar shows you four key pieces of data: the Open, High, Low, and Close (OHLC).
How it works: A little horizontal tick on the left is the opening price; a tick on the right is the closing price. The top and bottom of the vertical bar show the extreme highs and lows.
The Vibe: Professional, precise, but frankly, a bit cluttered to look at for long periods. It’s the spreadsheet of charts.
3. The Candlestick Chart: The Industry Standard
The Candlestick chart is the gold standard for traders who enjoy a little visual flair with their financial anxiety. Like the bar chart, it tracks the OHLC, but it uses a “body” to show the range between the open and close.
How to Read a Candle:
The Body: The thick middle part. If it’s filled (usually Red), the price closed lower than it opened (sadness). If it’s hollow or Green, it closed higher than it opened (celebration).
The Wicks (Shadows): The thin lines poking out of the top and bottom. These represent the “price rejection.”
Top Wick: How high the price went before someone said “absolutely not” and sold it back down.
Bottom Wick: How low it dropped before buyers stepped in to save the day.
Why Candlesticks Win:
They tell a story. A tiny body with massive wicks (a “Doji”) tells you that the buyers and sellers are currently in a prehistoric wrestling match and nobody is winning. A giant green candle with no wicks means the buyers are basically sprinting uphill.

f candlestick charts are the “novel” of the market, then patterns like the Hammer and the Evening Star are the plot twists. They signal that the current trend is exhausted and someone—either the bulls or the bears—is about to stage a coup.
Here are two of the most famous “main character” patterns you need to know.
1. The Hammer: The “I’m Not Dead Yet” Signal
The Hammer is a bullish reversal pattern that appears at the bottom of a downtrend.1 It looks exactly like its name: a small body at the top with a long lower wick.2
The Anatomy: A small body (color doesn’t matter much, but green is better) and a lower wick that is at least twice the size of the body.3
The Story: The market started the day by panicking and selling off hard. But, before the candle closed, buyers rushed in like a SWAT team, pushing the price back up near the open.
The Translation: “We tried to crash, but the buyers said ‘No thank you.'”
Pro Tip: Don’t just buy because you see a hammer. Wait for the next candle to close higher to confirm the “rescue mission” is actually happening.
2. The Evening Star: The “Party’s Over” Signal
The Evening Star is a three-candle bearish reversal pattern that appears at the top of an uptrend.4 It’s the market’s way of saying the sun is setting on your profits.
The Anatomy:
Candle 1: A big, strong green candle (The Optimism).
Candle 2: A tiny candle that gaps up (The Indecision/The Star).
Candle 3: A big red candle that closes well into the body of the first candle (The Reality Check).
The Story: Everyone was happy (Candle 1), then suddenly everyone got confused and hesitant (Candle 2), and finally, the sellers took control and shoved the buyers off the stage (Candle 3).
The Translation: “The hype has officially left the building.”
Pattern Comparison
| Pattern | Appearance | Location | Sentiment |
| Hammer | Small body, long lower wick | Bottom of a downtrend | Bullish (Potential Buy) |
| Evening Star | Big Green → Tiny Star → Big Red | Top of an uptrend | Bearish (Potential Sell) |
Note: Trading patterns in isolation is a great way to donate your money to the market. Always look for other clues—like high trading volume—to make sure the pattern isn’t a “fake-out.”
