A stock chart is a record of every trade, compressed into a picture. You do not need to memorise dozens of patterns to use one. Six questions cover most of what matters for a buy or sell decision.
1. Pick the right timeframe
Start with a weekly chart over several years to see the big picture, then move to a daily chart over the last 6 to 12 months for detail. A stock can be in a short-term downtrend inside a long-term uptrend; knowing both prevents a lot of confusion.
2. Read the candles
Each candlestick shows one period's open, high, low and close. A filled or red body means it closed below the open; a hollow or green body means it closed above. Long wicks show prices that were reached and rejected. You do not need to name the patterns. Notice whether recent candles close near their highs (buyers in control) or near their lows (sellers in control).
3. Identify the trend
- Uptrend: higher highs and higher lows.
- Downtrend: lower highs and lower lows.
- Range: price moving sideways between two levels.
Most strategies work better in the direction of the trend. Buying in a clear downtrend is betting that you know better than everyone currently selling.
4. Add two moving averages
The 50-day and 200-day moving averages are the most widely watched.
- Price above a rising 200-day average: long-term uptrend.
- Price below a falling 200-day average: long-term downtrend.
- Price far above the 50-day average: the stock may be stretched and prone to a pullback.
Moving averages lag. They confirm trends; they do not predict them.
5. Mark support and resistance
Look for price zones where the stock has turned several times. Support is where buyers stepped in; resistance is where sellers did. Broken resistance often becomes support. These zones are natural places for stops and targets. Draw zones, not exact lines; prices rarely respect a level to the cent.
6. Check volume
Volume shows conviction. Breakouts on high volume are more trustworthy than on low volume. Rising prices on falling volume can signal a tiring move. A large volume spike on a down day near support deserves attention.
A reusable checklist
| Question | Note |
|---|---|
| Long-term trend (weekly)? | |
| Short-term trend (daily)? | |
| Price vs. 50- and 200-day averages? | |
| Nearest support / resistance? | |
| Volume behaviour on recent moves? | |
| Events in the next 2 weeks? |
What charts cannot tell you
Charts do not know about the product launch next month, the debt maturing next year or the customer about to leave. Combine them with the business picture, as described in technical vs. fundamental analysis, and always define your risk before you enter.
