What a forex candlestick represents
A forex candlestick chart displays how the exchange rate changed during fixed time periods (for example, 5 minutes, 1 hour, or 1 day). Each candle summarizes four key prices for that period:
- Open: the price at the start of the time period.
- High: the highest price reached during the time period.
- Low: the lowest price reached during the time period.
- Close: the price at the end of the time period.
The candle body (the filled or outlined rectangle) shows the difference between open and close. A wick (also called a shadow) shows the high and low beyond the body.
How candle direction works (body colors and shape)
Candles are read relative to open vs. close:
- If close is higher than open, the candle body represents upward movement over that period.
- If close is lower than open, the candle body represents downward movement over that period.
Even without color, you can read direction from the placement of the body edges:
- The lower edge of the body corresponds to open or close depending on direction.
- The upper edge of the body corresponds to the other of open/close.
The wick length provides extra context:
- A long upper wick suggests the price traded higher but returned.
- A long lower wick suggests the price traded lower but recovered.
How to interpret range and volatility
To understand how much movement happened inside one time period, compare the vertical span from low to high:
- A candle with a large total range (long wicks, wide body) indicates larger price movement during that period.
- A candle with a small range indicates more limited movement.
This is a descriptive way to see intraperiod variability, not a promise about what comes next. Two candles can look similar while still occurring in different market conditions.
Example checks: reading one candle step by step
When you see a candle, verify your interpretation using these checks:
- Identify the time frame on the chart. Every candle corresponds to that exact period.
- Find the high and low: read the top and bottom of the wicks.
- Find open and close: read the top and bottom of the body.
- Determine direction: compare close vs. open from the body.
As a quick mental example: if the body is small but wicks are long, price likely moved away from open toward extremes but ended closer to open.
Limitations and what you cannot conclude
Candlestick charts are useful for summarizing historical price behavior, but they have clear limits:
- Past movement is not a guarantee: a pattern or candle shape describes what happened in that time period, not what will happen next.
- Time frame changes interpretation: the same market can show very different candle “structure” when switching from minutes to days.
- Context matters: a candle’s meaning depends on what happened before it, and on whether you are interpreting it within a consistent chart setup.
Because charts depend on the selected instrument and time settings, interpretations should be checked against the same data and time frame. Avoid treating any visual pattern as a certainty.
