For me, Palladium bought at 12610, sold at 14238 for 1628 profit per ton.... using an asp with 120 cargo space I have a trade route with 3 stops in 2 systems.... total profit per stop 123,000.......23,000........195,000 for a total of 341 K per lap about 3-4 laps per hour.
2,400 / ton round trip (1,400 gold, 1,000 performance enhancers). Prices have hardly budged in the week I've been exploiting it.
1815 cr/t palladium >> and 1150cr/t slaves in return .. using ASP with 128t no shields.. going to upgrade it to type 7 but dont know how much its FSD upgrade cost
