All pdBidr price variables are priced at the RRP, ie. at the node. This includes SRMC and trader price parameters. Hence bid Pricebands must be divided by the MLF in any calculations or conditions so that all price values are from the same frame of reference. For example if volume is to be allocated to the first PriceBand < SRMC it implies the first Priceband/MLF < SRMC.

pdBidr allocation logic includes a condition that ensures volume cannot be allocated to PB9 or PB10. This condition may be disabled.

Constraint_status data source is currently set by the Bid Parameter “Constraint Status” which should be set to 0 (no constraints) or 1 (constrained off). Under no circumstances should it be set to -1 (constrained on). Our analysis to date suggests that a dynamic constraint_status provides negligible benefit but increases rebids, increases code complexity and makes retrospective analysis more difficult.
