Not really... T+n (usually n = 2) would greatly impair ones ability to make consecutive trades, unless trading very small positions of very low priced (nominally speaking) stocks. Commissions may even be the deciding factor for placing such (day)trades.
Understood, right re commisshes except recently free unlimited commissions for USA traders using fidelity Ameritrade IB etc
Trading using margin is one of the worst things non profitable or new traders can do. Imho the right progression is:
Paper trade only, or tiny under 10 share trades at most, until one is consistently breakeven.... most will never reach that
Swingtrading initially then gradually test daytrading.
The worst so-called trading instructors peddle get rich quick images, claiming to make thousands of dollars daytrading sub-$10 notoriously difficult momentum pop and drop bs stocks.
Also useless are the legions of bullshit poser YouTube fake trader educators with zero blotters, no proof they even trade.
