I don't recall there's an exchange or a bot that supports that. Have you tried zenbot though? It's an open-source trading bot, maybe you can develop your own plug-in that supports it. It should be possible as long as the API allows automatic trading execution, but I don't know how complex zenbot could be. You might want to check out the bots list above, I recommend Gunbot if you want to try.
Well, so far that I know trading bot that usually used is Gunbot, --this could only perform the stop-loss process but I do know if it includes the changing orders. I don't know how it will work the automatic execution using a trading bot or auto-replacing orders. Just a tip before using this method or using their API, read always the exchange TOS and FAQ for this matter to avoid possible big losses if ever there is.
