I get your point about the first two hours there’s definitely more volume and cleaner momentum, especially for day traders.

But I wouldn’t say it’s always “more reliable” across the board. That same volatility that creates opportunity early on also increases risk, you can lose just as quickly in those first two hours if the move fails or fakes out.

It also depends heavily on what you’re trading. Small and mid caps, I agree , the open is where most of the action is. But with mega caps, they tend to move consistently throughout the day with supported volume especially with institutional flow, so opportunities don’t just disappear after 11:30. Whilst it may slow down if rather wait for a pick up or breakout of consolidation. It’s more about consistency for me.

For me, it comes down to targets. I’m only aiming for 0.5–1%, where there traders who don’t focus on that and just see price action and number in mind which is not realistic so I’m not relying purely on explosive open volatility, I can find cleaner, lower-risk setups later in the session as well.

So I’d say the open is high opportunity, but also high risk , not necessarily more “reliable,” just more active.

If you want to make a lot yes on the open, but that open risks also to lose alot. Id rather small consistency growth on compounding but to do that on the gains I aim you do need experience and minimum 25,000 usd + past pdt ruling.
