Chart Types & Price Representation

The ways a chart draws open, high, low, and close, and the scale it uses. 16 topics.

Candlestick Chart

A chart that draws each period as a body between open and close, with wicks to the high and low.

A chart that marks each period as a vertical line from low to high, with ticks for the open and the close.

A chart that connects one price per period, almost always the close.

A smoothed candle built from averaged prices, so the trend is easier to see and the real open and close are hidden.

A chart of bricks that print only after price has moved a fixed amount, so time is ignored.

A column chart of Xs and Os that plots price movement by box size and ignores time.

A chart of vertical lines that reverse when price retraces a set amount, and that change thickness when the prior swing is broken.

A chart that prints a new line only when price breaks the range of the prior lines, classically the last three.

Bars that each cover a fixed price range, so a bar closes only when that range is complete.

A candle colouring where an up close is hollow and a down close is filled, sometimes with a second colour for the prior close.

A line chart with the area under the line filled, so the path of price looks like a ridge.

A line of price, or of two series, with the region between the line and a baseline filled in.

The four prices that define a period: where it started, how far it went, and where it finished.

A historical price rewritten so that splits, bonuses, and sometimes dividends do not create false gaps.

A price scale on which equal vertical distances are equal percentages, not equal rupees.

A price scale on which equal vertical distances are equal price units.
