Somewhere to view order books, trade history,graphs etc for the DEX?
Blockscan has some basic information but not that good (yet) http://www.blockscan.com/order_book?asset1=BITCRYSTALS&asset2=XCP
Counterwallet is ok but I would be happy to see a real good explorer 
Actaully, there is a good one for SOG assets that is found here https://sogassets.com/ in a tablepress form. However I am sure this could easily be transferred to all assets on the DEX. I will get in touch with the devs and see if i can copy their code and add it to this site https://xcpassets.org/
