For SFE Night Scalper I just copy the MQL5 signal that's available at 95% risk through my MT4 terminal.
SFE Night Scalper trades during the Asian session with smaller profit targets but greater accuracy. SFE Price Action is active when there is more volatility - it often has small losses or no gains for a prolonged period, but it can make very large gains within a short time that makes all the losses back plus a nice profit. They are both profitable in the long term and that's why I run both on my account. 😄
