scalping needs professionals
scalping works by getting few pips in a very little time
some scalpers work on 1 pip only
scalping is very difficult as trader must be always alerted to recognize entries and exit points very fast.
as beginner, my advice is stay away from scalping till you are able to deal with very fast price moves in very little time
as time frame, scalpers mainly apply 1m to 15 m charts, to get more signals, since they are only interested in a pip or two, so they don’t need to apply large time frames
