I checked the volume on Friday and JPC had the lowest volume of any coin on our warning list. I checked it again today before deleting the market and the average volume for the last 7 days was 0.00603022 BTC so there was no way that a 3 BTC order was filled in the last day.
Delisting it was not a mistake. However, we are willing to add markets back if there is sufficient demand.

I don't know what numbers he checked, but when I was actually buying JPC a few hours before it was removed, there was a big order with over 3 BTC alone filled. I replied to his e-mail telling him, that I'm 100% sure that there was enough volume, but no answer yet.
I also noticed the big volume just before it got delisted. Someone sold about 160million JPC.
That may have been Bittrex selling the JPC they owned from the trading commissions.
