If I were a traffic engineer (is there such a thing?) then especially in systems like red dwarf stars where the habitable world is way down the star's 100D limit, I'd put a 'highport' at some convenient point - perhaps far above the elliptic, if it made sense - but 'in line' with the busiest trade route. With thrust 0 station-keeping, the port wouldn't even need to 'orbit' the sun, just hang there at 99.5 D of the star, then offer fast shuttle service to the planet for those who needed it. for a fee, of course. But those just passing through and flipping cargo and passengers, they could be on their way in a day and everyone would come out ahead.Well, depending on where you want to put them really. If it's known where, in relation to the planet, your 95D station or ship is located, then inbound ships can plot their jump entry to be in that area. For pure transfer traffic above/below the plane of the system eliptic is a good place to be.
