Hey all,

So I noticed later in the game (when I was able to purhcase large quantities of different goods in the marketplace) that when you purhcase a lot at a time the scaling is insane.

When selling, you always have a flat rate (minus the market cut or inflation or whatever)

When buying, if you buy say 3 Titanium at 30, the cost is close to 3 x 30 x inflation (but still more... market cut?) which is fine.

However, when buying say 200 Titanium at 30, the cost is astronomically higher than 200 x 3 x inflation! (Like over 18k! is the market cut that high when buying?)

I've tried hovering over the costs, but it never explains it.

What is going on here? Could someone please explain?

Hey,

Have you ever heard of the law of supply and demand? The law of supply and demand is a theory that explains the interaction between the supply of a resource and the demand for that resource. Generally, low supply and high demand increase price. In contrast, the greater the supply and the lower the demand, the price tends to fall. That's pretty much it. If you need great amount of some resource, economically it's worth to buy little portions every turn rather than all stock in one turn(planning in 4Х who would have thought! :O). AI tends to buy when stuff is cheap and sell when stuff is expensive.

Supply and demand is all well and good, but doesn't really answer anything.

Until an actual purchase is made, demand (price) does not go up, whether bulk or not & especially not compounded (just look at the stock market, if it worked like it does in this game well... it wouldn't work at all).  Not to mention that in bulk you usually get better rates regardless of supply and demand.

Also, by this logic when I sell large amounts I will always be selling for 1 dust per unit, but that's not the case.

I am interested in the calculations going on behind the scenes.

What, if any, are the optimal buy and sell quantities?

So I did some calculations and there seems to be absolutely no consistency in the marketplace purchase prices.

For example* (Dust Inflation @ x5.85):

* All of these prices are from the same turn

** The second round of Adamantium prices is after I made a single purchase that raised the prices of Adamantium (to see if the rates were the same, and they were vastly different even though the price went up)

*** I was not able to get the exact amounts over 999 dust as that info is trucated.  Testing withing 1000 dust gave the best results, but these rough numbers are still quite accurate regardless

Conclusions:

• There seems to be no correlation between the amount of total dust spent and the rate increase
• There seems to be no correlation between the number of items attempting to be purchased adn the rate increase
• Even with the same items, the rates vary, even within the same turn at the same dust inflation
• I can't figure out at all how the Dust Inflation is being used

Is there anyone who has looked at this before?

Is there any way to know how much I'm actually spending so I can improve the calculations? as I plan to make some graphs that show the rate changes depending on price and units purchased and dust inflation to see if I can find a single correlation that makes sense.

BadBecauseMad thoughts on these calculations?

It's probably also related to how much is present on the market after the transaction.

Maybe.

But if that's true, then the 'second round' of purchases for Adamantium above in the table should have gone up even more since there was less on the market AND the price was higher, but the rate of change lowered... :(

So confusing.

I expect it's something like a logistic between minimum and maximum prices. The maxiumum rate of change will be between the middle of hte two values, while the rate of change will be lowest with almost nothing and absolutely tons on the market.

But I am just guessing.

Maybe make a plot of amount on market vs price?
