Their is a new kid on the block and his name is dexeos.io. DEXEOS is a new decentralized exchange for EOS. At the moment it has no trading fees and because its on EOS it runs smoothly. The exchange has nearly all the EOS airdrops and the only exchange i know of that is trading Trybe token. No sign up is needed just log in with scatter.
When i first tried to make an order i thought maybe the site was down as it didn't load my orders but soon found out that you need to put the price in next to the arrows in the yellow's box i made. I was just clicking on the top buy order, you have to manually put in the price and amount :) Also sometimes the arrows don't show up until you hover your mouse over them.
Voting, staking, exchange API, and funding
Exchange API is coming soon it sounds like a pretty good idea this allows developers to put DEXEOS API into their Dapp to create their own token economy.
Funding is also coming soon in their words "Begin selling tokens through DEXEOS for your EOS-based project. DEXEOS supports the initial sale of token" sounds to me like you can run an ICO with them.
The Exchange has a nice layout but atm it has very low liquidity other then that its pretty solid.
