Do you need regulation in UK to sell signals in copytrading?

Hi, do you need regulation in UK to sell signals? It is a grey area and Copy trading and Auto-trading can be considered portfolio management by FCA, which it requires regulation.

FCA officially states: Copy trading allows investors to trade by automatically copying another investor’s trades, and we generally classify it as portfolio or investment management.

Does any strategy manager based in the UK know more about this? If so how do you go around the issue?

Please advice.

Thank you
