TradeDangerous is a profit optimizer that runs locally on your computer, using a local database of price data you enter as you fly (or by importing data from other commanders). It is an Open Source project to which a number of commanders have now contributed (thanks esp to ShadowGar, Gazelle, Smacker65)
Back in 1984 I scribbled hundreds of pages of price notes. Naturally enough, when I started playing ED I pulled up notepad and started typing out interesting prices... It quickly became unwieldy and so I started knocking out this little python script to figure out the best trades.
By best trades I mean much more than just which item has the most markup from this station.
TradeDangerous is designed to do everything from simply calculating what's hot at Dahan to very efficiently solving the "NP" problem of "exactly how rich can I get in 10 stops in a type 6 with a 12 ly jump limit starting with 42 credits?"
For complicated routes, a "checklist" mode will walk you through each step (dock at Dahan, buy 100 fish, jump to X, jump to Y, dock at station, sell, refuel, buy ...). And for X52 users it will even display the steps on your MFD as you go.
More importantly, TradeDangerous is Open Source - I've written it so that other developers can make use of the extremely fast and efficient calculation engine to build tools.
See the "CHANGES.txt" file for more updates.

==== DESCRIPTION ====
TD is a best profit calculation system that runs locally on your computer, designed to enable other programmers/power-users to easily build on it.
Running locally allows it can do much more work finding you that best trade. It can do much more than just tell you the highest value trade between two stations (which you might not even be able to afford!) It will find the load that makes the absolute best use of your cargo space and credits.
Better still - it can project that forward and calculate many hops for you, and then pick the best sequence: It may be most profitable to take 100 Gold from A->B, but if there's nothing worth buying at B, your next hop is a waste of time. And it takes the money you're going to make into account. When you have only 10,000 credits, it might be lucrative to Clothing A->B and Grain B->A, but if you've made 5,000 credits already, why aren't you picking up Fish B->C and then using the additional credits to allow you to start running Dom. Appliances C->A etc.
Because TD runs locally, it can figure out the full deal for you.
All of this is built in a modular way so that if you can easily pick up the TradeDB or TradeCalc modules and make your own front end to the data and to the calculation system.
OBTAINING:
TradeDangerous doesn't come with an installer - so it's not as easily accessible as it could be, yet. To get it running you'll need Python 3.4.1 installed.
Then, grab the latest code and data from BitBucket (https://bitbucket.org/kfsone/tradedangerous or for short: http://kfs.org/td/source).
Alternatively, you can use "git" to fetch and update it. Command line users can use "git clone git@bitbucket.org:kfsone/tradedangerous.git", or if you're not that adventurous, you could download Atlassian's "SourceTree" GUI and use that.

Enjoy.

==== CHANGES ====
(New changes occur frequently, I only update with significant releases here)
v7.3.0 Jul 05 2015:
. (ahamid/kfsone) "fromfile" support for command options:
- All commands will now look for a "fromfile" specifying default arguments
for that command .tdrc_{cmd} e.g .tdrc_nav or .tdrc_shipvendor,
- One argument-position per line, "--ly 20" is two lines but "--ly=20" is one,
- The fromfile argument is replaced with the arguments in the file,
- Looks in the current directory and then your user directory,
- You can also use your own fromfile as an argument prefixed with a '+':
trade.py nav +myfrom.txt
. (Fred Deschenes) "buy" now supports categories e.g.
trade.py buy --near sol metals,food
- to find food cartridges, use foodc or "food cartridges",
Jun 20 2015:
. (kfsone) Lots of new systems (until EDSC broke),
. (kfsone) Minor optimizations,
. (kfsone) Tweaks to edscupdate,
v7.2.0 Jun 14 2015:
. (Orphu) Created an import plugin that uses Frontier's Mobile API,
- See README.md for more help,
- Use "trade.py import -P edapi" to get started,
- Able to optionally upload prices it pulls to EDDN:
trade.py imp -P edapi -O eddn
. (maddavo) Fixed/merged lots of new systems,
v7.1.2 Jun 6 2015:
. (Dry411s) Diamondback prices
. (Orphu) Imperial courier price
. (kfsone) Maddavo Data import/refresh
v7.1.1 May 25 2015
. (kfsone) Added "--distance" option to "edscupdate" which shows the 10
closest candidates.
+ (kfsone) Over 500 new core systems
v7.1.0 May 11 2015
. (kfsone) #236 Unicorn (erh, Unicode)
- Added code to trade.py to catch wild unicode errors, esp under windows:
Windows console is NOT utf-8 based, which means that when TD tries to
print a unicode character, an error occurs. I've added code to catch
this early (TradeEnv.uprint) and code to catch it late (trade.py),
- Changed various file openings to "utf-8",
. (gazelle) Changed display of "adding/removing ships" in shipvendor sub-command
. (kfsone) #234 Change display of "adding ship" in maddavo plugin
. (kfsone) Fix submit-distances/edscupdate generating duplicate extra-stars.
v7.0.3 May 09 2015
. (kfsone) "run" command:
- Added "--show-jumps" (aka -J)
- Jumps are no-longer shown by default,
- Request #233 Jumps now include distance
- If start and end station of a hop are in the same system,
display "Supercruise to ..." instead of a jump
- When a hop involves multiple jumps using --show-jumps, it will
tell you the direct and total distances,
. (kfsone) Revamped the intro of the README.md (http://kfs.org/td/source)
. (gazelle) Corrected unicode system names (Argetlamh etc)
v7.0.2 May 05 2015
. (kfsone) Added "--demand" option to "run", filters based on demand.
CAUTION: Items with "?" demand will be ignored when using --demand.
If you want to enter demand values in the update tool, you will
need to use the "--use-demand" (-D) option of "update".
. (kfsone) Fixed #231 Exception when using --quantity in buy/sell
. (kfsone) --supply is now an alias for --quantity in "buy"
. (kfsone) --demand is now an alias for --quantity in "sell"
. (kfsone) Fixed #232 'supply' values ignored by "run"
v7.0.1 May 04 2015
. (kfsone) Minor fixes from forums
. (kfsone) Fixed issue causing some users to get a numpy import error
+ Extra data and Rares
v7.0.0 May 03 2015
CACHE BUILD REQUIRED (trade.py buildcache -fi)
"requests" packages is now required if you want to use "maddavO"s plugin
. (Avi) README.txt has been replaced with README.md
. (kfsone) "import" command (non-plugin behavior)
- Restored the default behavior of forcefully overwriting existing data
with values from the .prices file and deleting items that aren't listed
in the import.
- Added "--merge-import" option: only imports entries that are newer than
existing local data and only removes entries when there is an explicit
entry for it with 0 prices.
- Changed "--reset" to "--reset-all" because it's a scary command,
. (kfsone) Consistency of various commands:
- "demand" refers to what a station will buy,
- "supply" refers to what a station is selling,
- Changed several command options from "--stock" to "--supply",
- "--black-market" is now consistently spelled with a hyphen
(or just --black for short),
- "--bm" now has two hyphens in all uses (it was -bm in some cases),
. (kfsone) "market" command:
- Only show the age of items once,
. (kfsone) "nav" command:
- Fixed --refuel-jumps
- Added --pad-size to limit which stations will be listed/refuelled at,
. (kfsone) "buy" and "sell" commands:
- Added "--black-market" (--bm) option,
- Added "--avoid" option (accepts station and/or system names)
. (kfsone) Performance:
- Re-unified the StationBuying/StationSelling tables into StationItem,
- Added StationBuying and StationSelling views,
- Minor refactor of getTrades to reduce the pathalogical near O(n^2)
behavior it used to match buyers to sellers,
- Improved performance of nav command slightly,
- "import" plugin now uses the "requests" module, which means that
it will automatically download/use compressed .prices files when
they are made available. E.g. maddavo's .prices files now require
upto 5x less bandwidth,
- Added code to allow experimental use of numpy,See the "CHANGES.txt" file for more updates.
