The quality of sell and buy orders never match 100%, so sell orders and buy orders are matched even when the quality is different.
If the quality of the sell orders are higher than the buy orders, the quality the product is sold for will be downgraded, to a limit of aprox 10 quality points difference (as seen in James Folsoms post).
Equally, if the quality of the buy order is higher than the sell order, the quality of the sold product can be upgraded, under similar rules.
If this mechanism didn't exist, it would be impossible for most trade to happen, as most buy and sell orders are at opposite extremes of quality.
The limit of ~10 for upgrading or downgrading quality means that trades are often executed with a considerable quality gap, causing money to be created out of thin air.
For example the Buy order is 120Q, the sell order is 270Q. Product is bought for 130 quality, the product is sold for 260
I believe Daniel has a fairly plausible explanation, that fits the observations.
The only thing I can't figure is that the historical record shows that we have the existing system because Tom Willard was mad because C3s were stuck buying all the high quality stuff, and subsidizing profits for players.
If it's true the final solution, just shifted the problem elsewhere.
Edit: Actually, the more I think about it, I doubt that the money is created out thin air in Daniels example. I think those mismatches are resolved without creation or destruction of money. Eg when the buyer is asking for 330 and gets transmuted 120 quality, the seller is paid for 330 quality. There are of course different permutations of that depending on whether it favors the buy or seller. It likely isn't straightforward, I just think that given the GMs historical aversion to creating game money; it doesn't make sense.
Nonetheless, I sus

Hymy1,
In cases where the quality of the buy order is much higher than the sell order, then money is removed from the game. It's the same mechanism, just working in reverse. I didn't mention that in the post because I was worried the post was going to get to long.
It helps to partly offset the money that gets created when buy orders are for very low quality, while sell orders are for very high quality. However, I doubt as much money leaves the game in this way, as gets created. Corporations are all producing goods for higher quality than they purchase, and plenty of goods bought by countries are ordered for 120 quality.
The quality system has a large distorting effect on the flow of money in Simcountry, but it would be almost impossible to fix without completely removing or reworking the entire quality system, so the player base largely just accept it as a necessary evil, to enable the simulation to function.
