$ARTX is quite stable, traded 525u, completed 32 transactions of 515, finished 66,000 orders, consumed 3.4u, traded 340u more ÷ 32 ÷ 4 is over 2u, tomorrow I'll change to trading 513u per transaction to give it a try. If there's still a little short after completing the 32nd transaction, I'll add a bit more. We must reach the minimum of 65536, don't let it fall short by 1u, or I'll be upset the next day if I'm down by 1 point.
