Trader Tool

The Trader Tool is invaluable to any successful seafaring merchant. Those who truly understand its uses are destined for riches.


  • Enter all or part of the name of the commodity that you're interested in.
  • Select among the potential matches (Blue backgrounded boxes) with a left mouse click
  • For the selected commodity you'll see
    • Weight - some goods are too heavy to fit in the smallest vessels even when the hold is empty
    • Commodity Class or Classes - "imported" goods tend to bring better prices than "domestic" French Languedoc Violins generally bring better prices in a British port than Suffolk Cheese

Distance Slider

Use the convenient distance slider it's possible to restrict the ports displayed based on the distance you're willing to travel.

Sortable Columns


Sort (ascending or descending) by:

Port Name

A - Availability of that commodity

The most likely places to start looking for a good. Again, this is NOT updated in real time. There will be a dot in this column if the port shop has any on-hand. Oddly, SELL contracts are not reflected as being on hand. This has been reported to the game developers as a bug.

P - Ports able to produce that commodity

These are also potential places to establish an outpost if you wish to begin producing this good yourself

C - Ports that regularly consume that commodity


The distance in nautical miles from your current location


The price they will pay you if you're selling.

  • Double click on this column heading and the Best Price you'll be able to get for selling this good should be on top


The price you will pay them if you're buying.

Locate Port

Click on the reticule to focus the map on any port you select

Locating the closest source of a good

While availability is not updated in real time, is possible to locate the closest likely source of a good:

  1. Search for the good with the slider all the way to the right
  2. Click on the A column so that all ports with the good available are sorted to the top
  3. Slide the distance slider to the left until only one port has the dot in the a column. That's your closest source

Identifying a good potential cargo

  • Pick a commodity that your current port (or a nearby port) has on hand. Capital cities tend to be "sinks" or big consumers. It's often best to leave the capital city empty and plan on bringing back a full hold.
  • The most promising commodities tend to be those that are:
    • Light weight - more of them will fit on your ship with less wasted space
    • Not native to your next port of call e.g. French goods sell at a premium in British ports while British goods tend to sell at a premium in neutral ports with a lot of French trade.

Sort the port list ascending on Buy price. The top entry is the least you can expect to pay for that good. Mentally eliminate any ports that are too distant or are forbidden to you due to your nationality. Sort the Port list Descending on Sell price. The top entry is the most you can hope to get for that good. Again, eliminate the non-viable ports. Decide if the difference between the two prices is enough to make the trip worthwhile.


  • Assume that I've sailed to the neutral port Sant Iago and my next planned Port of Call is Kingston/Port Royale.
  • The port has Arctic Fox Pelts, Cheshire Cheese, Dutch Laudnum, and Sumatran Pepper available to buy.
  • Using the Trader Tool I have done the following calculations (actually the spreadsheet I set up did)
  • The Dutch Laudanum would clearly be the best cargo to return with
Commodity Weight Quantity/
Profit Percentage
Arctic Fox Pelt 144 0 3522 10722 30414 0 N/A
Cheshire Cheese 6.45 21 282 266 5922 -336 -5.67%
Dutch Laudanum 16 8 3522 699 5592 22584 403.86%
Sumatran Pepper 4.3 658 219 32 7008 14048 200.46%

Using the Trader Tool to Find yourself


It's possible to get an approximate fix using the trading tool.

  • Enter any commodity
  • Sort the list in ascending order by distance
  • Look at the three nearest ports You are in a triangle formed by the three
  • Given the relative distance you should be able to work out an approximate position
