I have one signal provider in mind that I can truly recommend. Up until recently I had the same problem... 8-9 hours at work, 2hrs in traffic, too tired to think about trading so I have experimented with many EAs and signal providers. Keep in mind that any provider that can make 6-10% per month with a low drawdown is a true gem. Beware of any signal provider who promises over 10% per month and has less than one year of LIVE verifiable results via a proven service like MYFXBOOK etc. Only trust LIVE accounts, demo accounts are useless in proving anything except how generous a broker's DEMO feed is, cuz you won't get those results on their LIVE feed.
Ok here is the signal provider I like and have used for some months including right now.

I am in no way affiliated, just sympathize with the request.
