Tick charts represent intraday price action in terms of quantity of trades: a new bar (or candlestick, line section, etc.) is plotted after completion of a certain number of trades (ticks). This aggregation type can be used on intraday charts with time interval not greater than five days. For example, a 2d 133t bar chart plots the price action for two days, defining open, high, low, and close prices every time the number of trades becomes equal to 133. In Charts, users are free to specify any number for tick aggregation from 1 through 10,000. The procedure of setting up the time frame, including tick aggregation, is described here.
For performance reasons, up to 8,000 bars can be initially loaded to a chart. The total number of bars will be also reduced to 8,000 as soon as 16,000 bars are plotted.
