A few months ago there was an issue with Etherdelta and some people lost their ETH and tokens.
Has the issue been fixed, is it safe now?
for me, im using
https://forkdelta.app , because no delay for buy and sell order in there, and than you can used
https://ethgasstation.info/ for set Gas price, so you will not be wrong in choosing the gas price and the transaction process will not be a problem
