A chart compresses trading information into an interval. A line often connects closing prices, a bar displays open, high, low and close, and a candlestick emphasises the relation between open and close. The chosen interval changes what you see; no timeframe is inherently profitable.
What you will learn
- Distinguish line, bar and candle information
- Explain nested intervals
- Identify incomplete candles

What each chart includes
A close-only line removes intraperiod highs and lows, so it can conceal a large excursion. OHLC bars and candles retain four values but still hide the exact path between them. Two candles with identical OHLC can have different intraperiod sequences. Never infer whether a stop or target was reached first from a single historical candle alone.
Timeframes are different samples
An hourly candle aggregates an hour; a daily candle aggregates a trading day defined by the provider’s clock. A five-minute decline can be a pullback within a daily advance, rather than contradictory data. Provider session boundaries can change daily candles. Always identify the timezone and whether the current candle is still forming.
Use a consistent comparison
Choose a context timeframe and an execution-study timeframe before inspecting results. Keep indicator settings and chart intervals fixed during a test, or document changes as a new experiment. Zooming until a preferred pattern appears introduces selection bias. Smaller intervals usually make spread and noise more important relative to a small intended move.
Key terms
- Timeframe
- The interval represented by each chart bar.
- OHLC
- Open, high, low and close for one interval.
Hypothetical worked example · Not live market prices
Worked chart study · Understanding Charts and Timeframes
- Assume twelve five-minute bars cover one hour.
- The hour opens at the first bar’s open, takes the highest high and lowest low of all twelve bars, and closes at the last bar’s close.
- If the last five-minute bar is incomplete, the hourly close and extremes can still change.
| Observation | Illustrative value / meaning |
|---|---|
| First open | 1.1000 |
| Highest high / lowest low | 1.1050 / 1.0980 |
| Last close | 1.1020 |

Common mistakes to avoid
- Changing the stated chart rule after seeing the outcome instead of recording a new test.
- Treating a historical description as a guaranteed future result or ignoring execution costs.
- Skipping the timeframe, source or invalidation condition before drawing a conclusion.
Lesson summary
A chart compresses trading information into an interval. A line often connects closing prices, a bar displays open, high, low and close, and a candlestick emphasises the relation between open and close. The chosen interval changes what you see; no timeframe is inherently profitable. Use an explicit rule, consider contrary evidence and practise without risking real money.
Practical exercise
Aggregate three imaginary five-minute candles into one fifteen-minute OHLC candle. Explain which intraperiod details the result omits.
