Still doesn't solve the problem. They'll just make the bogus sell orders on the ore instead once they realize that's how the system works.
You can't use any kind of auto-calculation system based on market values of anything, regardless of what formula you use, as people will find a way to pad the market values to their benefit. Exploiters are smart these days .
Actually CCP already has a system in place to calculate the actual value of goods in eve.
They only use the prices of goods when those goods change ownership. Low buy orders and high sell orders are ignored because no other player accepts the terms.
Let's say 4 market orders for trit are placed (each involving an arbitrarily large quantity).
A: buy order at 1.00 isk
B: buy order at 2.3 isk
C: sell order at 2.5 isk
D: sell order at 9001 isk
Only orders B and C are ever engaged in actual trade. A is unsatisfied since B overrides it, and D is unsatisfied because no one will pay 9001 isk per unit of isk. So only B and C impact the moving average.
The only exploit is if a person goes to a station with no orders for that good, post it way too high, then buy it with an alt. However, imagine the quantity of that good changing hands. Imagine the concerted effort necessary to inflate the average market price of tritanium. And exploiters have to pay both a tax (1%) and a broker fee (at most 1%).
So let's ignore broker and just say 1.5%. To add 1 unit of 1000 isk trit to the moving average costs 15 isk. If 10 billion units of isk change ownership every day at 2.00 isk, it takes 10,000 (10 thousand) 1000 isk transactions to increase the average to 2.997 isk per unit. That is 150 million isk lost to the black hole of market tax and broker fee.
The price exploiters post at doesn't matter (the higher they do it at, the fewer transactions are required but the same 1.5% is still lost in taxes/fees).
If someone wants to pay the fee to increase the perceived value of tritanium, they are welcome to do it.
That exploit is preventable by ignoring extreme outliers. But if someone wants to invest the taxes to increase the price, I say "let them."
