Start with a single candlestick
Each candlestick represents one time period (a day, a week, an hour) and shows four prices: open, high, low and close.
| Candle part | What it shows |
|---|---|
| Body (thick part) | Range between the opening and closing price |
| Wick / shadow (thin lines) | The highest and lowest price reached during the period |
| Green/white body | Closed higher than it opened (bullish for that period) |
| Red/black body | Closed lower than it opened (bearish for that period) |
Moving averages — the trend’s “smoothed” line
A moving average plots the average closing price over a set number of periods (e.g., 20 days), smoothing out day-to-day noise so the underlying trend is easier to see.
Trend strength: is there a real trend at all?
Not every stock is trending — many spend long periods moving sideways. The ADX (Average Directional Index) is a common tool for measuring trend strength regardless of direction: readings above roughly 20-25 suggest a real trend is in place; readings well below that suggest choppy, directionless price action where trend-following tools are less reliable.
Momentum: RSI and MFI
RSI (Relative Strength Index) and MFI (Money Flow Index) measure how “stretched” recent price momentum is, typically on a 0-100 scale. Readings above 70 are commonly read as overbought (momentum may be due for a pause); below 30 as oversold. MFI adds trading volume into the calculation, which some traders find gives a more reliable read than price-only RSI.
Volume — the confirmation layer
Volume shows how many shares changed hands in a period. A price move on high volume is generally considered more meaningful (more participants agree with the direction) than the same move on low volume.
| Price move | Volume | Common interpretation |
|---|---|---|
| Up | High | Strong conviction behind the move |
| Up | Low | Weaker conviction, worth watching for confirmation |
| Down | High | Strong selling pressure |
| Down | Low | Possibly a quiet drift rather than active selling |
Putting it together: a simple reading checklist
- What’s the overall trend? (Check price relative to a moving average, and ADX for strength.)
- Is momentum stretched or fresh? (Check RSI/MFI.)
- Is the move backed by volume, or thin?
- Where’s the nearest support/resistance, in case the trend pauses or reverses?
Bottom line
Chart reading is pattern recognition built from a small number of repeatable building blocks: candles, moving averages, trend strength, momentum and volume. Practice reading these on charts you already know the outcome of (historical data) before applying them to live decisions.
