OHLC

Open-High-Low-Close - a bar chart showing the price of the high (the uppermost part of the bar) and the minimum (the lowest part of the bar), the opening price (the line to the left of the bar) and the close (the line to the right of the bar). The color of the bar represents the bar closing higher (green) than the open price or lower (red) than the open price.

VOL

when zooming in the chart:

A 3-D chart showing volume as clusters. Each price tick represents the volume traded  at any given price. The maximum volume within the cluster is shown in red.

A cluster is displayed in green if the cluster's closing price is higher than the opening price.
A cluster is displayed in red if the cluster's closing price is lower than the opening price. 

The cluster is displayed in blue if the closing price matches the opening price.
