2) No wasted gas on failed transactions: Other Ethereum DEXs (etherdelta, forkdelta..) rely on the user to submit trades to the network. This also means that trades can fail, as multiple users can compete to fill the same order. DEX’s must be designed to prevents this from happening, so you’re always certain your trade will succeed and with the lowest gas cost.
3)Gas free cancels: market maker orders are publicly available and cancelling an order must not requires paying gas to invalidate it on-chain.
4) best UI design
5) No, etherdelta or 0X script : please i do not want an exchange like etherdelta, 0x or bitshares,
must be like idex.
