I have autopilot running for 2 days, so far I have found one trick, which is you should let it trading itself, but you need to set the trend yourself, for example, recently the trend of eur/usd is down and usd/chf is up, so when you setup the autopilot, you need to change the default Long&Short position to Only Short for eur/usd and Only Long for usd/chf. This way you limit the chance of a huge stop loss, which happens several times on my demo account.
As far as how to track the trend, I think there are plenty of resource online we can track and normally it is hard for us to stand in the wrong side. you just need to check a few times each day to see if the trend reverse, and if it does reverse, adjust the autopilot accordingly.
of course this idea may be totally wrong, considering i only use autopilot for 2 days
