My review is fully opposite because I trade scalping thinking it is out of risk. I don’t have sufficient patience for holding a trade for a long time.
What I think is scalping is much relieving trading approach than EA trading, hedging and swing trading.
Yes there are lots of downsides in scalping, however it's hard to make correct predictions for medium or long-term because range of potential outcomes increases with time non-linearly. Hence it's harder => less chances to be consistently on the right side.
It is dangerous, because you are always taking a new trade which never meets the previous parameters. This then skews all your statistics, leading to more failures.
Any trading method can be risky if you do not observe the risks in transactions, do not know how to wait for all the rules from your trading strategy to find market entries and do not know how to analyze the market.
