How to achieve running multiple instances of both the empty and the full version?

I was too scared in the morning regarding the empty position of $ZEC 622 and couldn't add margin, and I didn't know where to cut the position. I could only open a reverse order; if it drops back to 622 and I close it, I'll only lose around 140u. Has anyone experienced this? How should I resolve it? Do I need to add to the reverse long position? ૮₍ɵ̷﹏ɵ̷̥̥᷅₎ა
