Pricing vs Valuation

Contract Valuation: Contracts tab

When a contract is created, you select a future instrument per contract delivery line. This future instrument can then be changed on the main contract tab if the contract is not priced (partial or complete).

The Future Instrument on the Contract tab controls the valuation instrument of the contract delivery line.

Contract Pricing: Risk tab

The future instrument selected on the Risk tab on the pricing section will be the future instrument used for pricing. This can be changed per contract delivery line when there is no pricing fixed yet (partial of complete).

Note: A contract can have different valuation and pricing instruments.

For Futures To be fixed, the "Pricing period" is taken into account to determine the position of the asset in Mark to Market.

Example
Take a 100 MT (10 lots) delivery line 2014-P0001/1 with valuation period of "Oct-2014" and 2 pricing periods (extra pricing periods for delivery line are introduced by pricing rolling): "Nov-2014" (40 MT, 4 lots) and "Dec-2014" (60 MT, 6 lots).

On the Position (overview) screen for "Futures to be fixed", this delivery line is under "Nov-2014" (4 lots) and "Dec-2014" (6 lots) - but the contract To be fixed remains under October 2014:

The details for "Futures to be fixed" looks like this:
