Is there a target market value (buy orders + sell orders + assets) for investing in a Freighter to start seeing a meaningful return from the lower broker fees? I don’t want to drop billions on a freighter if my trading volumes are low enough that the lower tax rate doesn’t yet justify the expense.

If you have lower ISKs you can just activate remote trading addon and transport staff once a day from TTT (other stations/citadels will have lower amounts locked) with public contract. I would not invest in freighter more then 20% of my funds but would definitively switch to remote trader option. Or consider to use Praxis, it has good cargohold volume, no skill requirements and 7 low slots. Define to transport like 200m at a turn to avoid ganks.

Thank you! I thought the remote trading option required a freighter. I can use an Iteron Mark V and just use use the max isk/m3 rule.

What ship to use is up to you, just define correct cargohold amount in settings so bot can confirm that ship is correct.
