Question 1

What is the difference between a candlestick and a bar chart?

Accepted Answer

Both show the same four prices for a period: the open, high, low, and close. A candlestick draws a thick body between the open and close with thin wicks to the high and low. A bar chart draws a single vertical line with a left tick for the open and a right tick for the close. The data is identical, only the shape differs.

Question 2

Why do some charts only show one line?

Accepted Answer

A line chart connects just the closing price of each period and hides the open, high, and low. That strips away the detail inside each bar and leaves a clean view of overall direction, which is why it is common for a quick first look.

Question 3

Which chart type is best for beginners?

Accepted Answer

There is no single best type. A line chart is the easiest to read for direction, while candlesticks show more of what happened inside each period. Many people start on a line chart and move to candlesticks as they want more detail.
