Hey,
Got a quick question for those of you who know very well the market engine rules.
I shorted a small amount of bitUSD in mid-July and my short expired in August. I decided to let it ride the order book instead of covering or rolling it over. But then the price dropped, causing my collateral to fall below the required amount. If my short hadn't been expired I would have been margin called, but it appears that because it was expired, it stayed on the order book at feed price.
Was I margin called, or since it was expired it wasn't what happened? Will I have to pay the 10% penalty for being margin called? Now that the price has risen significantly (right now the BTS value is higher than when I initially shorted), am I able to simply buy back the bitUSD and keep the BTS profits for the short?
Thanks for the answer!
