James, thats kinda what happens. With your Buying/Selling strats.
Products are put on the market, based on the selling strat of the corps. and price is reduced when their are no sales. Requests are put in the same way, and adjust up to meet the prices.
In the last couple days, EP has got from oddly green, to outrageously red. I run -1/3 for buying, that is, i start at 99%, and increase by 3 each month. Many of my corps started experiencing shortages of EP, with a demand of over 100M units. I checked out some of my neighbors, they weren't have any problems. I looked at their buying strat, at the bottom of their corp. They started buying at 108%. So because they were willing to pay more, (or just used the default setting,) they didn't experience the same problem, or atleast not as quickly.
Thankfully, i've got tons of EP stockpiled. I used direct trading to move stuff around, and resupply my corps.
How ever, if i was able to pick any price, i could further increase the demand for EP, so no one could buy it, this week at least. Then charge such high prices, that your corps would either take out loans, and close, or you're corps would just stop operating. Further, i could create such a dramatic demand, that many people may be forced to buy over inflated EP fir GC, via the direct trading. So what??? When i'm done with EP, i could do services, then HTS, then.. then.. then.. and you'd be forced to figure out a way to stockpile unrealistic back-ups, just to keep your head above water. Maybe not you, but with out some safe guard, we'd quickly run off players that can't spend Trillions, and Trillions, just to make a few B a GM.
Nah, its good to keep a ceiling price.
