A price chart is just a picture of what a stock has done over time, with time running left to right and price running bottom to top. That part is easy. What throws people is the detail crammed into it. But a chart is built from a small set of ideas, and once you know them, you can glance at one and understand the story it tells. Let us build it up piece by piece.
The candle: one bar, four facts
The most common chart is made of candlesticks, and a single candle is cleverer than it looks. Each candle covers a slice of time, say one day, and packs four facts into one shape: where the price opened, where it closed, the highest it reached, and the lowest it fell. That is a lot of information in a single mark.
The thick part in the middle is the body, and it stretches between the open and the close. If the close was higher than the open, the candle is usually colored green, meaning price rose over that period. If the close was lower, it is usually red. The thin lines poking out of the top and bottom are the wicks, and they show the highest and lowest prices touched before the period ended.
Timeframes: the same stock, different stories
Every chart has a timeframe, which is how much time each candle represents. On a daily chart, each candle is one day. On a weekly chart, each is a week. Switching timeframe completely changes the picture you see. A stock can look like it is crashing on a five-minute chart and calmly climbing on a yearly one, all at the same moment.
This is why timeframe is the first thing to check. A short timeframe shows the noise of the moment. A long one shows the big picture. Neither is wrong. They are answering different questions. Zooming out is often the best cure for panic, because a scary drop on the daily chart can be a tiny blip on the yearly one.
Trend: the direction that matters
The single most important thing to read from a chart is the trend, which is just the overall direction price is traveling. An uptrend is a series of higher peaks and higher dips, like walking up a staircase. A downtrend is lower peaks and lower dips, a staircase going down. And sometimes there is no trend at all, just a sideways drift, where price bounces in a range without going anywhere.
Spotting the trend is more useful than obsessing over any single candle. One red day inside a strong uptrend is a stumble, not a reversal. Reading trend keeps you from mistaking normal wiggles for something meaningful.
Support and resistance: the floors and ceilings
If you watch a chart long enough, you notice that price often stalls at certain levels, as if it hits an invisible floor or ceiling. A support level is a price where the stock keeps stopping its falls and bouncing back up, because buyers tend to step in there. A resistance level is a price where rallies keep running out of steam, because sellers tend to appear.
These levels are not magic. They form because lots of people remember those prices and act around them. A price that was a stubborn ceiling for months becomes meaningful, and if the stock finally pushes above it, that old ceiling often flips into a new floor. Watching how price behaves around these levels is one of the oldest ways to read a chart.
A word of caution
Charts show you what has happened, not what will happen. Patterns rhyme, but they do not repeat on command, and no chart can promise the next move. Reading a chart well means understanding the current situation clearly, not predicting the future with confidence. Treat it as a map of where price has been, which helps you make sense of where it is now, and be honest that the road ahead is never guaranteed.
Putting it together
Start with the timeframe so you know what you are looking at. Read the trend to see the overall direction. Notice the support and resistance levels where price keeps reacting. And use candles to understand the detail of what buyers and sellers did within each period. That is the full grammar of a basic chart, and it is enough to turn a jagged mess into a readable story.
