There is no such thing as a free money trade. This is the trap that scalers fall into. ---I'm playing with house money--- No you're not. You're playing with your money. Scaling in or out is bad long term on ANY timeframe.
Sure there is, not on an intraday timeframe, but it is there.
The big joke is all of these teachers want to make you rich, it takes a real professional to find an edge. It took me a decade, and yes I've worked on a desk.
Joe that works as a dentist and trades part time will never have a chance.
