This indicator combo displays real‐time Level II market data as well as up/down volume by tick for the current bar on the main chart panel. It works on any instrument, time‐frame and chart type.

The Level II data is displayed to the right of the price bars as a horizontal histogram that extends out over the price bars. The histogram bars are color coded to visually identify the corresponding bid/ask levels. The price axis of the chart is used to show the price of each bid/ask level. In addition, the actual size of bids vs. asks at each level as well as a total bid/ask is printed down the right side of the histogram.

The second indicator included in this combo displays volume as a vertical progress‐like bar to the right of the Level II histogram. This indicator displays the volume of the current bar. It shows, by tick, how much volume is occurring above, at and below the previous bar's closing price. It does this using three configurable color bars representing the relative proportion of the underlying volumes. The actual over/under volume count is displayed at the top and bottom of the bar.

These indicators only support live data and will not plot historical data.
