Understanding the Momentum Score
The Power Hour Momentum Indicator generates a score from -100 to +100 based on four key factors. Here's how to interpret the numbers:
Bullish Scores (+25 to +100)
- +80 to +100: Very Strong Bullish - High probability trend continuation
- +65 to +79: Strong Bullish - Favorable for power hour longs
- +45 to +64: Moderate Bullish - Watch for confirmation
- +25 to +44: Weak Bullish - Use smaller position sizes
Bearish Scores (-25 to -100)
- -80 to -100: Very Strong Bearish - High probability trend continuation
- -65 to -79: Strong Bearish - Favorable for power hour shorts
- -45 to -64: Moderate Bearish - Watch for confirmation
- -25 to -44: Weak Bearish - Use smaller position sizes
Neutral Zone (-24 to +24)
Choppy/sideways conditions. Power hour could break either direction. Wait for volume confirmation before entering trades.
How The Score Is Calculated
Price movement strength vs. session open
Recent volume vs. earlier session volume
Price above/below institutional flow level
Overall daily performance vs. previous close
Updates every 15 minutes during market hours (9:30 AM - 4:00 PM ET)
Why Open & Close Matter
The first and last hours of the trading day are typically the most volatile. Our bot is most active during these periods to capitalize on the increased volume and price movement. Smart money moves during these windows.
- Opening Hour (9:30-10:30 AM ET): Overnight news, earnings, and gaps create explosive moves.
- Power Hour (3:00-4:00 PM ET): Institutional rebalancing and position adjustments drive volume.
- Volume Surge: 40% of daily volume occurs in these two hours combined.
- Volatility Premium: Options premiums are highest during these periods.
Opening Hour Playbook
The market open sets the tone for the entire session:
- Gap Analysis: SPY gaps >0.5% often continue in the gap direction for 30-60 minutes.
- Pre-Market Levels: Watch overnight highs/lows—they become key support/resistance at open.
- Volume Confirmation: High-volume breakouts in first 15 minutes have 70% follow-through rate.
- Reversal Signals: If SPY fails to hold gap direction by 10:00 AM, expect fade back to previous close.
- News Catalysts: Economic data releases at 8:30 AM create immediate directional moves.
Power Hour Strategy
The final hour often determines daily outcomes:
- Institutional Flow: Mutual funds and ETFs rebalance in final hour—follow the money.
- Trend Continuation: Strong intraday trends often accelerate into close.
- Option Expiration: On expiry days, SPY gravitates toward max pain levels.
- Reversal Patterns: Weak trends often reverse in power hour as day traders close positions.
- After-Hours Setup: Close direction often predicts next day's gap.
Avoid the Dead Zone
Mid-day trading (11:00 AM - 2:00 PM) often lacks conviction:
- Low Volume: Institutional traders take lunch—retail dominates with smaller size.
- Choppy Action: Ranges and false breakouts are common during lunch hours.
- Reduced Bot Activity: Our algorithms scale back during low-conviction periods.
- Wait for Setups: Better to be patient than force trades in sideways markets.
Time-Based Entry Rules
Optimize your entries based on market hours:
- 9:30-9:45 AM: Fade extreme gaps, follow strong breakouts with volume.
- 9:45-10:30 AM: Trade pullbacks to VWAP, watch for trend establishment.
- 11:00 AM-2:00 PM: Avoid new positions unless clear breakout with volume.
- 2:00-3:00 PM: Position for power hour moves, watch for institutional flow.
- 3:00-4:00 PM: Trade trend continuation, be ready for end-of-day reversals.
Risk Management by Time
Adjust position sizing based on market hours:
- Opening Hour: Reduce size by 50%—volatility can spike unexpectedly.
- Mid-Day: Standard position sizing, but be selective with entries.
- Power Hour: Can increase size slightly—trends are more reliable.
- Last 10 Minutes: Close day trades—overnight risk not worth reward.
- Holiday Weeks: Reduce all position sizes—volume and volatility drop significantly.
