If there was a way to chronicle every item that was restockable for a nice profit, trust me, people would be all over it. Unfortunately, there isn't really a way to do so because of the way the market works. some items fluctuate a lot based on supply and demand and others just tend to fall.
A form of knowing which items are good to restock is by checking the news page, or last weeks news page. Look for new items released between 70-90 rarity, if you buy them when they first come out, you can sell them for some awesome profit. However, you can't horde these and always buy and sell them because they'll eventually(a week to two weeks after they're released) fall in value to below whatever the stores are selling them at.
but if thats all boring go to space weaponry and try your hand at restocking neocola coins.
