How about if my token is not listed there ? I have ATHENA.
ATHENA‘s ICO is still ongoing, usually the exchange list token after ICO. Athena is an ERC20 token, most likely it will be listed in etherdelta first.
It is better for you to ask about exchanges information in the ANN thread.

EtherDelta is a bit complicated for the average crypto-maniac, let alone for beginners. The best advice is to HODL the asset until it becomes listed on a more mainstream exchange or use escrow and trade it privately. Can also go to coinmarket and find the markets where it is listed, if that hasn't been done yet, and keep watching for it on the list there until it appears.
