Scalping is like any other trading and risky too just like any other so without proper knowledge it is difficult. For scalping,,one needs good calculation of risk ,Stop loss as market prices and spreads fluctuates within seconds. Scalping can go wrong because it doesn’t typically use Risk-Reward ratio. Scalping seems fun when you’re winning but as soon as you start losing its not fun anymore. Most of the traders will eat up most of their capital before they call the experiment a failure. Overall,it is not a viable trading method.
