How to calculate how much he is trading up and down, and also set short and long?

$ARC Specifically, this is how I pulled out of a good minus on $TRADOOR . Now I can close the overall to zero. But $TRADOOR has really hooked me, and most likely I will continue the fight.
To be honest, this hellish coin takes a lot of time and nerves; it would be good to close it and move on
