Guys, calm down. Please read the announcement before you react. All you need to do is to transfer your tokens to the MEW that you control your private keys and not the exchanges.

//Just make sure you have your eBTC tokens on a wallet (you control/own the private key) before block 4462000.
If the tokens are already on the private wallet you associated with EtherDelta, you can leave them there. Just don't leave any tokens on ED's smart contract.//

Another thing, technically when you do it all correctly everything will be an automatic process of swap as you follow the steps of instruction for the swap.
