Scalp Trader PRO monitors and detects trends on the MT4 chart using moving averages, price action, and some other powerful tools ignoring weak trends and looking only for the strong ones.
Once there is a potential kick in an opposing direction, the system will use its meticulous intelligent algorithm to scan and analyze it and determine if it's just a temporary move or not and signals a continuation pattern starting.
It generally trades every week, but sporadic days with no trades can exist, this is how it avoids unnecessary risk for the account.
