I am trying to create a tool for myself to figure out how much to buy commodities from my alternate account by my main accounts fleet carrier so that both my alternate and main make money and sell from the carrier at a value that someone will purchase from my main and still be able to make money. I would like to be able to tell the tool to refresh when I need to set the prices for buying and selling and have it just automatically calculate the values. I have done a lot of Office programming in the past and so really all I need is to know how to tap into something to get a list of the commodities data. Anyone have any ideas?
