@ Welimar:
Regarding copy trading from FBS, I personally have never used it. Perhaps there are readers who have used it and would like to share their reviews here.
Whether it is profitable or not depends on the trader you choose. Look at the average monthly profit percentage generated by your chosen trader. As far as we know, some copy trade systems apply a commission per transaction, but there are also brokers that offer free copy trade, where the trader whose trading is copied will receive a bonus from the broker for each copy. It is possible that the traders with commissions are of higher quality (possibly). Brokers usually provide data on the performance of traders offering copy trade.
