V12 to V13 Transition

v12 to v13 Transition Notes

This page is a temporary helper for commanders moving from Trade Dangerous v12-era habits to the current v13 command surface.

The normal documentation pages describe the current tool directly. This page exists only to catch old examples, scripts, muscle memory, and forum posts.

Install and rebuild

Trade Dangerous v13 requires Python 3.12 or newer.

After updating, rebuild your local database:

trade import -P eddblink -O clean,skipvend

For a full Spansh seed/rebuild:

trade import -P spansh

Command changes

Old habit	Current form
trade ... after a normal install	trade ...
trade rares ...	trade buy --rare ...
trade trade A B	trade direct A B
trade update	trade import -P eddblink
trade station ...	trade local ... or trade market ...
trade shipvendor ...	ship vendor data comes from imports

trade trade ... is still available as an alias for trade direct ..., so existing direct-comparison scripts have a gentler landing.

Option changes

Old option	Current form
--planetary N	--planetary N
--link-ly	use command-specific --ly or --ly-per
nav --refuel-jumps	use a specialist fuel/neutron route planner
run -v	use normal/verbose output, --raw, or --checklist
run --max-routes	--routes
run --odyssey / --od	--settlement

Rares

Rare lookup is now part of buy:

trade buy --rare --near lave --ly 160

This is a live-market view. It shows rare commodities that currently have market supply in your database.

Route planner

The current route planner is database-driven and supports station or system endpoints:

trade run --from sol --credits 5m --capacity 64 --ly-per 20 --jumps-per 2
trade run --from "sol/abraham lincoln" --to lave --credits 5m --capacity 64 --ly-per 20 --jumps-per 2

At typical jump ranges, set --jumps-per 2 or higher for multi-hop routes that need to cross more than one system jump per trading hop.

Data import

For most users:

trade import -P eddblink

For clean rebuilds:

trade import -P eddblink -O clean,skipvend

Plain .prices import remains available for deliberately maintained local files, but import plugins are the supported path for normal updates.
