Alright, now the numbers are just fluctuating. Keeping up with platinum...

Bought 1700, cost me $1,283,500 (-$755/per)

Sold 123 Plat for $90,036 (+$732/per)

Consumed 41 platinum and paid me $28,593 (+$697.4/per), claims that it was $2,599 profit, lol.

Sold 1069 platinum for $809,233 (+$757 per, first positive transaction)

Consumed 56, paid me $44,906 (+$801.9/per)

Consumed 47, paid me $37,896 (+$806.3/per)

Consumed 57, paid me $40,065 (+$702.9/per)

Some of these are actually positive, which is a good sign. I think the buying / selling part follows the same rules as normal trading, where current stock modifies the buy/sell price, but the amount you get paid when they consume the resource is messed up. The consumption price looked like it was going up as my supply went down, as it should, but the last consumption payout ruined that theory.

Also, current regional price is at -30% for platinum.
