Current Order Book (COB)

In the Current Order Book (COB) column, you can find graphical indication (bars) and/or numerical values of the amount of pending orders. In the configuration menu available by right clicking the column and choosing Configure…, you can find the following options:

1. Trade side. You can choose the trade side you would like to see the data for: Bid, Ask, or both. To do so, activate the corresponding checkboxes before Show Bid and Show Ask.

2. Extended display. Activate the Extended checkbox to turn on the display of liquidity that was previously available at the corresponding price level.

3. Aggregate display. If activated, each price level on the ask side displays the liquidity available at this level plus the liquidity available at all the levels below it all the way down to the best ask. Similarly, on the bid side, each level displays the liquidity available at this level plus the liquidity available on all levels above it up to the best bid.
Note: If this option is activated, Large Lot Tracker will not be available. Find more info on Large Lot Tracker below.

4. Set maximal depth. Use this option to limit the amount of price levels for which the liquidity is shown. For example, if you activate this option and set the maximum depth to 10, you will be shown the liquidity for ten levels above the center including the best ask and 10 levels below including the best bid.  The system will also display the aggregate liquidity for the ten best ask and ten best bid levels above and below the diagram, respectively.

5. Background color. Use this option to set a new color for the background of the column.

6. Bars/numbers. Choose which data representation you would like to see: bars only, numbers only, or both.

7. Style options. Use this option to:

  • Split display: Bid and ask sides will be aligned by the opposite borders of the columns.
  • Inverse display: If you have selected Split display, choosing this option will mirror vertically the bid and the ask sides.
  • Align display: If Split display is off, you can align both bid and ask data by the left border, the right border, or the center of the column.

In addition to the above, you can configure the Large Lot Tracker indicator that can be added to the COB column. Large Lot Tracker provides a simulated indication of the largest single pending orders at the corresponding price levels. To be indicated, the order must meet two user-defined conditions:

  • The size of the order must be above the threshold percentage of the total liquidity at the relevant price level.
  • The size of the order needs to be above the threshold percentage of the largest total liquidity that is currently present on the COB.

To add and configure the Large Lot Tracker:

  1. Right-click on the Bookmap chart and select Heatmap Settings.
  2. Activate the checkbox to the left of the Large Lot Tracker tab and navigate to this tab.
  3. On the Large Lot Tracker tab, specify both threshold percentages.
  4. Close the configuration window.

The Large Lot Tracker will become visible in the COB column. It is displayed as a vertical line within the liquidity bar at the relevant price level. Its position within the bar is defined by the ratio of the order size to the total liquidity size at this level.

Note: The Large Lot Tracker data is simulated by a proprietary mechanism and is not provided by an exchange. It does not guarantee 100% accuracy. This feature is not available if Aggregate display is activated for the COB column.
