Charts: Patterns Part 1
Background
It is believed that Candlestick trading first
appeared sometime during the 19th Century. The development of the
Candlestick is credited to Japanese rice traders and it is more
than likely that the concept evolved over many years into what
we see on our charts today.
Formation
Just like the traditional Bar chart, each Candlestick
displays an open, high, low and close over a given time period.
Depending on the fill of the body you can tell at first glance
whether the candle closed higher or lower than it opened.

It is also important to pay attention to the high
and low formations displayed by the shadows/ wick/ tails. These
can form the basis of important Candlestick patterns that can help
predict the future market direction.
Candle Vs Bar Vs Line
Most people prefer using a Bar or a Candlestick
chart over a line chart because of the extra information displayed
to the user. A line chart is unable to show highs and lows during
a set time period and therefore it often fails to display vital
information about the price action. As you can see from the picture
below the same data over the same time period can look very different
depending on the chart you use.

The reason why an individual would generally prefer
to use a Candlestick over a traditional Bar chart is completely
aesthetical. After all, both are displaying the same data but the
filled Vs hollow structure of a candle’s body is very easy
on the eye and quick to interpret.
