not to be harshed but i think etherdelta is one of the worst online exchages sites out there. there were many bad feedback and reviews of users around the net balantly accusing etherdelta because of poor service due to its buggy and verry slow interface, sometimes it also eats up your etherium balance without any valid reason, resulting for you to be clueless and ended up scratching your head.
By and large it is so. Earlier I used this exchange, but now I do not even come to try to trade there. Too many complications with transactions that often fail and eat Ether. I always now wait for the coins to go to other more reliable and high-quality exchanges. This exchange is convenient only because originally fresh coins based on ERC-20 are traded there.
