yes this is true sometimes it is best to sit and do nothing but not sure it will make you money but it will save you from losing any
The ability to sideline/stay out when things are not clear is no doubt important. I'm a bit too trigger happy and am always amazed when I talk to people who say they sat the entire session without being able to pull the trigger.
