Expert advisor vs Trading signal
Look-alike pair
Full entries: Expert advisor · Trading signal.
An expert advisor is software that executes trades automatically inside a trading platform, while a trading signal is a recommendation to enter or exit a trade that a human or another system must act on. The single difference that matters is execution: an expert advisor acts, a trading signal only suggests.
