To do any transaction in EtherDelta now we have to higher the gas. Sometimes it is never executing that until we increase the gas to 50 gwei. This is around 5 USD. This is big cost for small transactions. Do you know any best practices we need to follow when doing deposit, withdraw and trades in EtherDelta (specially in these days)?
In reality, there's nothing you could do if you want to trade.
Lower gas == More waiting for transaction confirmation. I found this site for checking the right gas price

If the problem with high gas/low amount of transactions per sec will not be resolved soon - Etherdelta will die.
Every action on Etherdelta now cost ~ 200k gas + 45 gwei = 11$.
