Approx 95% lose scalping or day trading.
4.5% are mixture of breakeven to 500k a year.
0.5% make blunt of the profits.
I was associated with brokerage in mid 90's for a year, so first hand saw numbers for past ten years of customers. I have managed money for others for decade besides my own funds since 1978. Won couple of real money contests, though
@Scataphagos won more contests and much larger rate of returns, one of few traders I admire on this site.
Reading your posts, you have spent the money before making it and don't have a clue on what you are doing wrong. You have wasted much much time, maybe even more so than most. "Iron clad discipline"? What is your sample size of back testing/forward testing?
Most don't believe in my approaches to learning, many say you have to do it with real money, I think it so wrong. Think one does demos with 10k and triple it three separate times, Ninjatrader would be more accurate way of demo.
Swing trading way to go, you have to make 100% + in day trading/scalping just to pay for years' worth of commissions. Better to use 60 minute bars, buy support/sell resistance offers smallest risk than doing breakouts. Check out Head and Shoulders patterns. And above all study patterns at ends of moves. Look to do few trades a week, aiming for 5 to 1 reward to risk. No hurry, forward trade six months.

@Scataphagos, excellent charting trader, he's better than me.
Stop using indicators, you like most don't know the game is rigged using them.
Good luck
