This thread isn't another /whine thread, or one of those do it my way threads, because I want to pay 4k for energy always. A lot of QQ going on, and speculation that doesn't really explain what's happening. I'm fine with 4-6k prices. If it goes up, well, that's just going to be the cost of playing.
This is just a suggestion, (possibly one that's already been mentioned several times already) if the developers read this and are interested in stabilizing the energy markets at a certain range. Obviously though I can't be sure they do, so for what's it worth.
It's probably not to difficult to implement a progressive transaction cost. I think it's probably a better solution, because if it's done smartly it would be a decent compromise. It allows prices to fluctuate and keep markets profitable and interesting to use, but will prevent a steady climb in prices that don't represent an accurate market value..
The higher a selling price goes beyond a certain point the higher that transaction fee becomes. At some point those who just buy and sell to make a few hundred crown per transaction will find it unprofitable. The prices of the energy being sold will have to go down accordingly in price for it to remain profitable, and people aren't going to have an incentive to sell their energy for less so energy traders can make money moving energy from one column to the other.
If say 10k was deemed unacceptably high by developers, maybe the transaction fee raises up to 60%. Meaning they'll only make 4k per sale. They would have to buy the energy for less than 4k to make a profit. There's a bunch of other scenarios it covers, but I don't want to blah blah blah. Just an idea.
TLDR; Scale "Transaction Fees" to the selling price of energy. Raising slowly within ranges that are considered acceptable by the designers, and raising rapidly (geometrically) as it passes that point.
