It is really a shit exchange. Keep wasting user money on fail transaction e.g. issue order (even though etherdelta does not earn from this error).
The user experience is frustrating.
The order book and trading history seems never sync for hot markets. This just traps people from sending incorrect order and loose tx fee.
I think etherdelta should be responsible for keeping the order book and trading history sync.
What a shit exchange!!!!!
I just realized that etherdelta place order using their own server without sending tx to eth blockchain.
Then why the fuck they don't do order matching in their server, but instead they send the order eth blockchain and waste user tx fee?
Their order matching algorithm is worse than a undergraduate project.
