Other Resources

1.Each resource has a base price. The base price of each product is explained in in-game help, as HELP:Base prices and will be skipped here.

2.Each resource is produced by 3 ports only. There are 7 resources and 21 ports. The market price update takes place once per 3 days. You can see when is the next resource update in Market page.

4.To define price, first we compare the existing resources between ports. See example below.

5.Once these prices are adjusted, they are further affected by the total amount of their stock in warehouses as explained here:
viewtopic.php?f=19&t=4225

To understand how exactly the prices are fluctuated in each cycle, I'll give an example below, with wood.

A)Wood base price is 8 gold per crate.
b)During the cycle, first of all, the 3 producing ports of wood are checked for wood reserves. Let's say
Port A has 4000 crates left
Port B has 23000 crates left
and Port C has 67998 creates left
Then based on the rule of supply-demand, the prices will be set as follows:
Port A will sell in the new day with 7 gold per crate.
Port B with 6 gold per crate.
and Port C which has the greatest stock (and normally wants to sell out) sells at the lowest possible price which is base price-3, in our example it is 5.

Then all other ports are set to buy at the base price which is 8.
All, except 3.

Again, during the last update, we check for wood reserves for all the other ports. We find the ports with the lowest reserves. These 3 ports will now pay the highest prices for wood. If port D, port E and port F had the lowest reserves, with F having the lowest, then the prices will be set as following:
Port D pays 9g
Port E pays 10g
Port F pays 11g

The reserves that are taken in mind for this calculations, are based on the trade that took place in the last 72hours.

So we will end up with this result:
-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
Port A selling Wood at 5g per crate (General Rule: Base Price - 3)
Port B selling Wood at 6g per crate (General Rule: Base Price - 2)
Port C selling Wood at 7g per crate (General Rule: Base Price - 1)
15 Ports buying Wood at 8g per crate (General Rule: Base Price)
Port D buying Wood at 9g per crate (General Rule: Base Price + 1)
Port E buying Wood at 10g per crate (General Rule: Base Price + 2)
Port F buying Wood at 11g per crate (General Rule: Base Price + 3)

Note: If the resource quantity difference between highest port and a port is 10M or less, the price will not change.

Then, the prices for each port may be affected by the total amount of wood at their warehouse, as explained here:
viewtopic.php?f=19&t=4225

These prices will be maintained for 72 hours. (You can get a full list of current prices through your active ports page, in Market page menu.)

This leaves a span of profit ranging from 1gold to 6 gold per crate.
There are 3 exceptions to this which are created because of the crate value:
-Tool crates are the most expensive, therefore the only one allowing up to 8gold per crate profit (-4 to +4 from base price with Ports starting at +-2 of Base Price instead of +-1)
-Food and Cotton are the cheapest, therefore they allow a profit of up to 5gold per crate ( the 6 producing ports start at Base Price -2 instead of Base Price -3.)

72 hours*

edited, thanks

i gota ask now...Is this still correct?

"The reserves that are taken in mind for this calculations, are based on the trade that took place in the last 24hours."

If so first 2 days of trade don't actually effect price then?

edited again, thanks

Think i got a typo.
"Then all other ports are set to but at the base price which is 8." -> Should it be "set to buy"

1.)shouldn't it be port C selling for 5, port B for 6, and port A for 7?

2.)is there a way to check the reserves of each port?

The Keynesian theory of economics suggests that supply determines price. If there is a high supply than demand must be low. Therefore, the price that the goods are sold at must be lowered to get rid of your supply. This same concept can be noticed in high volume ports such as the Tortuga to Tzogos route. Since high volumes of goods are bought, the supply of goods in each port decreases. When this happens and the next update occurs, the prices in those ports to buy will increase because there are a lower number of goods to be sold and there is still the same high demand for these goods. If this has not put you to sleep by now, imagine having to take a whole two semesters of this crud in school.

I understand that, I was suggesting a typo, because he had said it was the way I suggested earlier in the post...

is there an answer to my second question?

Yes, there is a way. Clink on the active ports link in the upper left of the screen( the thing that looks like a ship). This will list the port name, population, goods produced and stock of goods. If you roll over the number in the stock column it will show you how many crates are still in the port. This page is only good for the ports that you have a warehouse in. The other way to check involves switching manually from port market to port market. There you can see how many crates are left and the time until the next update. I hope this answered your question.
