The trouble with scalping (and I have said the many time earlier, so apologize the repitition ahead of time!) is that the gains are small, so a single big move against you can wipe out months of gain.

This is called lopsided strategy (if there is any), and this requires constant attention which is impossible for a human. Therefore, scalping is almost exclusively done by bots with stringent risk management in place. Funny, even then those bots fail quite frequently during high volatility.
