Setting Prices

Prices of items/ships/whatever are stored database-style in the program. There can be a unique entry for each combination of item and region. Each entry contains 7 values:

  • Buy Low
  • Buy High
  • Buy Mean
  • Buy Median
  • Sell Low
  • Sell High
  • Sell Mean
  • Sell Median
  • Build Cost

There are also several ways to create price entries, or edit the data you already have:

  • Market Transactions
  • Buy/Sell Orders
  • Exported Market Logs
  • Eve-Central or Web based prices
  • Manually

First Lets look at Market Transactions and Buy/Sell Orders.

If you provided Eve-MEEP with your Full access API key, it will automatically keep track of everything you buy and sell on the market. This data obviously is good for getting an items price, since you just paid that price for the item. So, if you just bought Tritanium in The Forge for 2 isk each, Eve-MEEP will use 2 for the price of Tritanium from The Forge. Pretty simple. It also has the advantage of easily staying up-to-date with items you buy frequently. The disadvantages are that market prices change quickly, you have to buy or sell the item for Eve-MEEP to notice it, and it has to take place on the market (Contract information is not available through the API).

Buy and Sell orders need to loaded into the program manually. If you open your wallet in Eve and check your currently open orders, there is a button to export them to a file. Eve-MEEP has a similar button on the finances page to import that file. The process of setting price is the same as loading market transactions. Advantages are that those values represent the price you will be getting the item at, should the orders move. Disadvantages are that your orders might not be at all representative of the market.

Next, Exported Market Logs.

A market log can be exported from the market window in Eve-Online. This text file contains all the buy and sell orders for a particular item in a particular region. It also contains how many items from the different orders have been bought or sold thus far. This I’ll call the Movement. Movement gives us a rough idea as to how much of an impact that order has on the market. So to import the file, we use the window found under Tools>Prices>Compile Prices.

Here we have some options as to what data to collect, and if we want to filter anything out. Lowest and Highest are self-explanatory, simply the 2 extremes of the buy and sell orders (after filters are applied). Mean and Median are found through computations of all the orders (after filters).

Mean is calculated by summing Price * Movement per order, then dividing that total by the total amount of movement.

Median is a bit more complicated programmatically, but found by literally counting and finding the middle price of all the orders.

Advantages of using the market logs is that we have all the data that could currently affect the price of the item. Disadvantages are having to manually load them in, and markets are constantly changing.

Finally, Eve-Central and Manually editing prices

Lets say you never are able to go to a region and get a market log for an item, you cant buy it, but you want to know its price (or you know it already and want to enter it). Use the window found under Tools>Prices>Edit Prices.

Window for manually editing prices

The first page here is a very basic wrapper for the system. Select the item, select the region, then just plug in your numbers. Click apply to save the data and not close the window, or click ok to save the data and close the window. Pretty straight forward. If you select an item/region combination that already has data, those values will be filled into their proper field. This page is also where we can get the price of the item via Eve-Central. In the upper right corner of the window there is a button labeled import.

Clicking this button will have Eve-MEEP query the website Eve-Central for the mean buy and sell price of the item for the selected region. Easy! Make sure to not slam Eve-Central too much at once. The second page of this window is more of a raw data view. It’s a bit awkward to use because of the sheer amount of the data, and does not have any real advantages unless you know what you are looking for.

Other ways of manually setting prices is through the mining window (Tools>Prices>Mining) and the POS fuel window (Tools>Prices>POS). Each of these windows also has their own way to get prices from websites, such as the Matari Mineral Index. What region do the prices in these windows reflect? Whatever your default region is (selected through the preferences window). The POS window has the added bonus of not only importing POS materials, but also salvage parts and data cores! These are not displayed yet, but it does get that data.
