STOCKPILING
once you start stockpile just hit the cash button to gain tanks and turrets.   since you dont attack anymore sell all your jets. you should  max out on business and residentialand military. you should also know that
troops=.5 networth
jet or turret=.6 networth,
tanks =2 networth
tech points=2 networth
you should buy military units as much as possible. and spend the rest of the money buying tech. You should sell all your your goods about a few days before the end of the reset. when you get  the money you get from selling spend it on the private market. If your goods did not sell you will have to login alot and spend your money 10 minutes by 10 minutes.
