Offer Table
About
The Offer Table screen offers a stack showing the volumes and
prices for the next declared offer pair. Alongside this a variety
of supporting data streams are available with this including the
total declared prices and volumes (capped at MEL) and generation
and dynamic data.
To see more information about a particular unit the user can
click on the unit name and this will give an option of viewing the
'BM Unit Operations' chart which shows what the unit has been
doing.
On this chart it is possible to examine the information at the accepted/declared
bids/offers at a selected group of units. By default the first 20 units on the table will be selected.
Then information about these units can be seen for those selected by using 'Pricing Unit Details' >
'See Declared Offers...'. The selected units can be changed by clicking on the cell containing the unit
name without click on the link on the name itself.
