Yep, and there was 2 btc volume in one of those 7, so for now(not for long tho, if there is not direct connection to dev, the next attempt may be there next week) PKB should be OK on trex.
One thing on trex, you can buy your own order (just verified). So actually, in accordance with their rules, you need to spend 0.5% of 1.4btc(0.007btc) to keep the coin listed.
Hint about self buying: Why some coins get such big day trade volume? LOL>
