Great topic... in doing thousands of trades this past year I've found:
+ the single best way to trade is intraday swing trading
Buy open range breakout by 10am and use a trailing stop on half position and hard stop just under premkt low on the rest, closing that between 3:30 and 4.
The whole idea of targets = epic fail. Use trailing stops.
Right re no late day decision making, I almost always fail if I enter after 11am.
Intraday swingtrades are best because no overnight gap risk plus you don't have to be so exact in timing orb/ opening scalps.
Classic daytrading 5 to 8 minute scalps is getting tough lately, shakeouts are frustrating.... small size for all day long trading works better. But you've got to use trailing stops on half position for when there's midday reversals.
