In 2000, a type of investment strategy called Mirror Trading was born. In the beginning, they only copied the algorithms generated by automatic trading. The developers allowed traders to observe the history of trades they generated, or shared. Traders could then make their investments based on these proven strategies, thus creating a trading community.
Later, this became a modality in which traders copied the operations of others without considering it a strategy in itself. This is the origin of the boom in social trading as an investment tactic, which is currently in great demand, even for money managers.
