What is Trade Dangerous? Trade Dangerous Crest

TradeDangerous is set of powerful trading tools for Elite Dangerous, organized around one of the most powerful trade run optimizers (TRO) available.

The TRO is a heavy hitter that can calculate complex routes with multiple-stops while taking into account the profits you make along the route.

The price data in TradeDangerous is either manually entered (by you) or crowd sourced. (e.g. using the included eddblink plugin to access EDDN data.)

What can it do for me?

You're in a ship with 8 cargo spaces that can make 8.56 ly per jump; you're willing to make upto 2 jumps between stations, and we want to see how much money we can make if in 2 trade stops (hops).

trade.py run --credits 5000 --capacity 8 --ly-per 8.56 --jumps 2 --hops 2

If we ran this, TD would search the galaxy for trade runs. But it could take us days to reach some of them. So lets say we're currently at Kummer City in the Andere system.

trade.py run --from "andere/kummer city"
    --credits 5000 --capacity 8 --ly-per 8.56 --jumps 2 --hops 2

(The above represents a single line)

That's a lot to type. TD is designed to support laziness when it comes to typing, so it allows for all kinds of short-cuts.

trade.py ru
    --fr and/kumm     find a station matching 'kumm' in a
                      system matching 'and'
    --cr 5k           'k', 'm' and 'b' are recognized suffixes
    --cap 8           8 units of cargo
    --ly 8.56         maximum distance *per jump*
    --ju 2            maximum 2 jumps

The default for hops is 2, so I didn't have to include it.

You can also use "=" to connect an option with its values:

trade.py ru --fr=and/kumm --cr=5k --cap=8 --ly=8.56 --ju=2

With the data at the time I write this, this produces:

ANDERE/Kummer City -> ANDERE/Malzberg Vision
  ANDERE/Kummer City: 6 x Titanium, 2 x Polymers,
  G 224-46/Lorrah Dock: 7 x Coltan, 1 x Lepidolite,
  ANDERE/Malzberg Vision +8,032cr (502/ton)

This tells us our overall route (line #1), what load to pick up from the first station, what to sell it for and pick up at the second stop and where to finish and unload for our final profit.

Note that it could have just told us to pick up 6 Titanium (the max we could afford) or 8 Copper (the highest profit we could fill up with), Instead, TD crunched hard numbers and maximized the earnings of every cargo space AND credit.

TIP: Last stop

Consider the last hop of a route as "best dumping ground". It is the only step TD doesn't think about "what next", so it's possible to arrive at a station that doesn't have much (or anything) worth buying. To avoid this, it's worth asking TD for 1 or 2 additional hops.

trade.py ru --fr=and/kumm --cr=6.2k --cap=8 --ly=8.56 --ju=2 --hops 5
ANDERE/Kummer City -> G 224-46/Lorrah Dock
  ANDERE/Kummer City: 7 x Titanium, 1 x Copper,
  G 224-46/Lorrah Dock: 8 x Coltan,
  ANDERE/Maury Terminal: 2 x Indium, 4 x Titanium, 1 x Copper, 1 x Aluminium,
  G 224-46/Lorrah Dock: 8 x Bertrandite,
  ANDERE/Maury Terminal: 4 x Indium, 4 x Titanium,
  G 224-46/Lorrah Dock +26,540cr (663/ton)

Malzberg was a great place to sell, but not such a great waypoint.

TIP: Earn as you go

TD takes into account the money you make along a trip (see --margin), in the 5 hop route we see the cargo loads changing as TD sees you becoming able to afford more expensive-but-profitable wares. This is another reason it can pay to ask for more hops than you intend to make.

How do I get there?

While one of TD's sub-commands, "nav", can help with that:

trade.py nav and/kumm --via g224-46 andere --ly=8.56
System     JumpLy
-----------------
ANDERE       0.00
LTT 14542    6.16
G 224-46     3.71
LTT 14542    3.71
ANDERE       6.16

We can also just ask TD to give us more detail with our trade run using the "--show-jumps" option or it's short-cut "-J":

ANDERE/Kummer City -> ANDERE/Malzberg Vision
  ANDERE/Kummer City: 6 x Titanium, 2 x Polymers,
  Jump ANDERE -> LTT 14542 -> G 224-46
  G 224-46/Lorrah Dock: 7 x Coltan, 1 x Lepidolite,
  Jump G 224-46 -> LTT 14542 -> ANDERE
  ANDERE/Malzberg Vision +8,032cr (502/ton)

Getting more (or less) detail

All TD commands can be asked more or less detail using either "--detail" (short-cut -v) or "--quiet" (short-cut -q). These are incremental, so "-vvv" or "-v v v" ask for 3 levels of increase, "-qq" asks for 2 levels of quiet.

trade.py run --fr And/Kum --cr 5k --cap 8 --ly 8.56 -J -vv

There's a lot going on here: . Fine detail about stations (distance from star, has black market, etc), . "score" tells us how TD ranked this based on factors such as total gain, supercruise distances, number of jumps, etc, . Expected purchase/sale costs and rough data age (some crowd-sourced data can appear to be very old if it hasn't changed), . How much we expect to gain each hop and the cr/ton we make,

Most users tend to use the in-game route planner and prefer the cleaner "--summary" presentation:

trade.py run --fr And/Kum --cr 5k --cap 8 --ly 8.56 -vv --summary
ANDERE/Kummer City -> ANDERE/Malzberg Vision (score: 8035.649800)

    Expect to gain 3,426cr (428.25cr/ton)

  Load from G 224-46/Lorrah Dock (729ls, BMk:N, Pad:M):

        1 x Lepidolite      428cr vs      813cr, 53 days vs 8 days
    Expect to gain 4,606cr (575.75cr/ton)

It's been a long time...

So you installed TD and you got crazy and you asked it to calculate 150 hops for you, and there was silence. If you specify the "--progress" option it'll tell you what's going on.

TradeDangerous: Setup

At the moment, the primary interface to TradeDangerous' goodness is through a command line tool, "trade.py". I've built TD in a modular, open source way so that other programmers can use it to power their own tools; hopefully tools with web or graphical interfaces.

For instructions on how to get setup see the setup guide.
