Those pesky shorts again!

[taughtus]

Really trying hard to get my small brain round this subject, and hare been following the posts avidly. Most of which are very enlightening.

But some help please. I did a test short for a total as follows showing in my OPEN SHORT SELL BitCNY Oders

100.00  4.45          0.00  -445.00 BTSX
10.00    5.154      5.154      51.54 BTSX
100.00  5.2074  5.2074    520.74 BTSX
1.00      5.2901  4.5001        5.2901 BTSX

So if I understand correctly I have sold 211 CNY which I did not own ? Or have they just been lent to my account?

However, my account has registered an increase of nearly 242 CNY.

This looks like pretty weird magic to me!
