As part of simulating the economy, we need to keep track of what goods a planet has, and how many of those goods are being produced and consumed. All such information is held in the trade table.

Column Usage
amount How many dt of this good the planet currently has in stock.
produced How many dt the planet produced in the last week. Production includes from resources and also industry etc.
consumed How many dt the planet consumed in the last week. Consumption can be by residential or other facilities.
bought How many dt the planet bought from ship cargo this week. This value is not included in the production figure.
sold How many dt the planet sold to ships this week. This figure is not counted as part of consumption.
weeklyin Weighted total of dt gained (produced and bought).
weeklyout Weighted total of dt lost (consumed and sold).

The weeklyin and weeklyout is updated each week. The last week's total of (produced + bought) is added to half the previous weeklyin. Same for consumed + sold for weeklyout. Not sure how this will be used yet, but may give a better picture of what is needed.
