How the hell do they do it

good day everyone,
i have seen comps where traders are achieving up to 300% return in a comp. does anyone have a clue on how they do it. they are obviously scalpers, but does anyone know what strategy they are using?

They usually overleverage, overtrade, overeverything their accounts to the point of gambling.

It’s good for a short period of time but not risk management-friendly and not good in the long haul.
