Forex Chart Types

Candlestick charts originated in 18th century Japan for rice trading. Steve Nison popularized them for Western traders in 1991. They are now the universal standard in forex and financial markets.

What a candlestick shows:
- Body (thick part): Open-to-Close range. Green/white = bullish (close > open). Red/black = bearish.
- Upper wick: Shows the High above the body
- Lower wick: Shows the Low below the body

Information packed into one candle:
- Where price opened (top/bottom of body)
- Where price closed (opposite end of body)
- The highest price reached (top of wick)
- The lowest price reached (bottom of wick)
- Directional sentiment (bullish or bearish body)

Why candlesticks beat other chart types:
Candlestick patterns — doji, engulfing, hammer, shooting star, morning star — are visual signals impossible to see on a line chart. These patterns are the foundation of price action trading and are taught in every serious forex education program.

Key candlestick patterns to learn:
Bullish engulfing, bearish engulfing, pin bar/hammer, doji, morning star, evening star. These are covered in detail in the Candlestick Patterns Forex guide.

Bar charts (Open-High-Low-Close, OHLC) display the same four data points as candlesticks but in a different visual format:

Structure:
- A vertical line represents the High-Low range
- A small horizontal tick to the LEFT: Open
- A small horizontal tick to the RIGHT: Close

Reading bars:
- If right tick (Close) is higher than left tick (Open): bullish bar
- If right tick is lower: bearish bar

When bar charts are preferred:
- Professional institutional traders — many discretionary macro traders use bar charts by convention
- When looking at many bars simultaneously — bar charts are slightly more compact than candlesticks
- Specific pattern recognition: "outside bar" (equivalent to engulfing candle)

The practical difference:
Bar charts and candlestick charts show identical information — the visual representation differs. The candlestick body makes direction more intuitively obvious (color-coded), which is why most retail traders prefer candlesticks. Bar charts require more experience to read quickly.

Line charts plot only the closing price for each period and connect them with a line. All open, high, and low information is discarded.

When line charts are useful:
- Getting a quick overview of the big-picture trend on a longer timeframe
- Clean visualization without the noise of intraday high/low range
- Identifying major support and resistance from close prices only

Why line charts are NOT used for active trading:
- No candlestick pattern recognition possible
- High and Low data is lost — you cannot see where stop hunts occurred, what the daily range was, or whether a level was actually tested
- Spreads and intraday volatility are invisible

The Heikin Ashi alternative:
Heikin Ashi candles are a modified candlestick that averages price to smooth out noise. They are useful for identifying trend direction cleanly but distort actual price levels (the open/close shown is an average, not the real price). Good for trend-following overlay; not for precise entry/exit.

Bottom line: Use candlestick charts for all active trading. Use line charts for occasional big-picture overview on weekly/monthly timeframes.
