correct me if im wrong. a trend follower will enter once and forgot the whole thing untill target reach.
a scalper hs to learn and practise precise entry on every trade, they can't afford to make mistake.. they exit early and change position as fast as lightning coz there's no time for stop loss. they may or may not have hedging positions. in a trend, they ride the waves up and down. they're ahead by several steps before the price moves just by looking at the chart. they've contigency plan in their underwear, just in case.
at the end of the day, what matters most to a scalper are , who got the most pips and what is the value in dollars are that pips and what is the duration in time u got tht result. thats wt matters most.
so...don't be surprise if a scalper enter a trade against a trend. they know wt to do and to survive.
to practise tht u must challenge yrself to get 100pips in one hour's time , and keep improving once the target is achieved. how u do it is up to you as long as mission impossible is achieved.
