You need to go off site to find the real information.
peeps just feed you false info here trying to protect their trade runs, which is total .
You make money by trading in rares, you need a hauler stripped and upgraded to be able to do at least 16 tons and 18 Size jumps.
Find a station that has rares 150 jump distance from another station with rare commodities , find an i between station for refuelling ( scoops a waste of time in a hauler, fuel is so cheap and you need the hauler to be light as, so no shields, no guns.
Rare commodities arehighlighted in yellow on the commodities list.
Rares seem to stock from 1-10 units every 10 minutes, try to find two rare station with stock of 10's.
Rare trade routes are happily given from other sites, no one gives them here,
Then run them in solo mode for no grief 350K to 600k per hour ( 15k to 18k/ton )depending on your ship.
Trade in normal commodities total waste of time, like about 80% of this game if you are trying to get ahead.
im on holiday so don't have my notes, but would happily PM all my route info on rares.
it is boring as hell to trade, but ED has forced it upon us now with the earning nerfs.
only the players who exploited rare trading at the beginning have enough money for big ships, casual players don't stand a chance, so yeah my info is free to whoever wants it.
