Extremely worried - Forex signals and EAs regulated?

Hi,
So in Forex last August I lost over £20k from trading myself and pretty much gambling.

I was short on cash so I joined this company which sold signals and EAs. They employed me to be a sales person. They are based in the UK. I was making £1k a month on average which considering my last job paid £5 an hour was pretty good. The £20k was inheritance.

Now people are telling me signals and EA autotraders are regulated in the UK meaning to sell them you. need a license? Is this true guys as I have since quit the company but I am worried I could get in trouble. Are signals and EAs investment advice?
