I think we need this, since when you want to sell piled cargo, or you want to buy, lets say, 160 cargo (so you can just unload&load and leave station), you have to buy it in many steps.

Yah, i buy 11 loads of cargo whenever i start to trade, we need an option to turn off the cap to buying\selling over 16, just so that people who don't know what they are doing won't buy a couple hundred.

if they can afford a couple hundred, they should know what they are doing

Nalar does have a point.

While the load/unload max should stay 16... the sell/buy should be upped to 160 so as to speed up trading.

One who has 180000 and can afford 100 rare metals can handle the responsibility of buying them.
