Validate that no position at cost is allowed to go negative. This routine checks that when a posting reduces a position, existing or not, that the subsequent inventory does not result in a position with a negative number of units. A negative number of units would only be required for short trades of trading spreads on ...

For all the entries, convert the posting's position's CostSpec to Cost instances. In the simple method, the data provided in the CostSpec must unambiguously provide a way to compute the cost amount. This essentially replicates the way the old parser used to work, but allowing positions to have the fuzzy lot specificati...
