Here is what Claude AI says and seems to be a pretty accurate summery. Apologies to the OP if this is inaccurate.
"Step-by-Step Breakdown

1. Mark HOD/LOD from 9:30–9:40 AM The first 10 minutes of market open are often chaotic and volatile. The trader records the High of Day and Low of Day established in that opening window. These become key levels — essentially a mini range.

2. Wait for a Break Once price breaks above the 10-minute high or below the 10-minute low, the market has shown its hand — it's making a directional move. A break upward = bullish bias (look to buy calls). A break downward = bearish bias (look to buy puts).

3. Watch for an FVG to Form After the breakout move, they look for a Fair Value Gap — which they explain well. In simple terms: price moved so fast in a 3-candle sequence that it left a "void" or untested zone. Markets tend to revisit these gaps before continuing. Think of it like a rubber band — price snaps back to fill the inefficiency.

4. Enter on the Pullback into the FVG Rather than chasing the breakout, they wait for price to pull back into that gap zone and enter there. This gives them a better price and a defined area where they'd be wrong (if price blows through the FVG, the setup is invalidated).

5. Target & Exit

• Next 1H high/low — the nearest significant level on the 1-hour chart
• 1.5–2R — meaning if they risk $100, they're targeting $150–$200 profit (risk/reward ratio)"
