Portfolio calculates the effect of daily shifting through pro-ration of monthly data. This allows the impact of daily shift adjustments to be seen in the context of the portfolio. The calculated values remain in monthly granularity even when using daily shifting. Note the following points when using daily shifting:
- The minimum granularity for optimizers (GA and LP) and random portfolio generation is Monthly.
- The Gantt chart displays project dates and markers at the monthly scale.
- Daily shifting requires addition calculation, which may increase processing time of some functions.
