Well said Harashi, also timing is important. What may appear to you as sellers liquidating at a loss may actually mean they've made their profits and now they're just clearing the bank to move on to their next trade. Someone else said it before...now may be the time to buy them out under costs to resell later.I hate the opposite more; artificially inflating prices. I see a lot of effort going into skewing prices high. Competition will naturally drive prices down to their balance point. What you're experiencing is market normalizing, it's just not the frequent 'norm' anymore. Especially on FV. Prices spike back and forth as sellers at both ends tip the balance around. With the modern situation in EQ, I would expect that extra volitility.
Regardless, you're simply complaining your margin isn't high enough in the end. If the margin isn't high enough: pick a different sector, improve the efficienies of your process, or go 'out of business'. That's how open markets work. It's worth remembering that a lot of players are not trying to be billionaires, pay bills irl through EQ, or well-equip a box crew. I would not assume players are pricing in ignorance or stupidity. Their behavior is simpler than that. They are pricing at a profit margin they are satisfied with ... wether they realize it or not.
