Single hourly orders need to be defined with at least two price steps, minimum price (EUR -500) and maximum price (EUR 3000). Price independent orders are orders where buy or sell volume will be placed at the minimum and maximum price steps for all the intended hours. The member will receive a schedule of delivery equal to the specified volume for this hour, regardless of the price level.

Single hourly orders can also be defined with several price steps; these orders are called price dependent orders. Members who submit price dependent orders, accept that Nord Pool will make a linear interpolation of volumes between adjacent pair of submitted price steps to find the correct traded volume for that member. 

Example of a price independent order (24 hours)

In this example the participant wants to buy 70 MW in all individual hours 01-24 at any price between -500 and 3000 euro.

Price Hour		-500	3 000
01		70	70
02		70	70
03		70	70
:
24		70	70

Example of a price dependent order

In this example the participant wants to  trade different volume in each hour depending on price. 

In hour 01, he wants to buy 50 MW at any price between -500 and 50 and to sell -10 MW at prices between 55,1 and 60 and -30 MW between 60,1 and 3000.  Should the price become 55,05 Euro, his traded volume will be -5 MW due to linear interpolation. 

Price Hour		-500	50	50.1	55	55.1	60	60.1	3 000
01		50	50	0	0	-10	-10	-30	-30
