I think PAMM accounts or copy trading is a better opportunity for new traders to get exposure in the forex market but only if the professional trader you are using is actually skilled but that’s not an easy task. Traders rarely show their past performance and it’s hard to trust them without knowing their trading background.I am rare to use signal service, but I think depending on each trader's will, there is an investor trader that like to looking ways to invest in forex like following signal trading, investing in a PAMM account, or subscribing copy trading.
