virtual ReservedBuyingPowerImpact	GetReservedBuyingPowerImpact (ReservedBuyingPowerImpactParameters parameters)
	Computes the impact on the portfolio's buying power from adding the position group to the portfolio. This is a 'what if' analysis to determine what the state of the portfolio would be if these changes were applied. The delta (before - after) is the margin requirement for adding the positions and if the margin used after the changes are applied is less than the total portfolio value, this indicates sufficient capital.

virtual GetMaximumLotsResult	GetMaximumLotsForDeltaBuyingPower (GetMaximumLotsForDeltaBuyingPowerParameters parameters)
	Get the maximum market position group order quantity to obtain a delta in the buying power used by a position group. The deltas sign defines the position side to apply it to, positive long, negative short. More...
