Geometric Alpha
Geometric Alpha: The Intraday Pattern Recognition Cheat Sheet

Chart patterns are not arbitrary geometric shapes; they are the visual representation of Market Psychology in Conflict. Every triangle, flag, or shoulder represents a battle between aggressive buyers and defensive sellers. For the intraday speculator, identifying these patterns provides a map of where "order clusters" reside and where a sudden shift in momentum is statistically likely to occur.

Operating as a pattern trader requires a transition from "predictive" thinking to "reactive" thinking. We do not guess that a pattern will complete; we wait for the Confirmed Breakout accompanied by significant relative volume. This clinical approach ensures that we are positioning ourselves alongside institutional liquidity rather than front-running a formation that may ultimately fail. This cheat sheet provides the technical blueprints for the most robust patterns in modern day trading.

Bullish Continuation Patterns

Continuation patterns signal that the market is taking a "breather" before resuming its primary uptrend. These are typically the highest-probability setups for momentum scalpers.

Bullish
The Bull Flag
Structure: Vertical pole followed by a tight downward-sloping channel.
Entry: Break of the upper trendline on high volume.
Target: Height of the pole added to the breakout point.
Bullish
Ascending Triangle
Structure: Horizontal resistance line with rising higher lows.
Psychology: Sellers are firm at a level, but buyers are increasingly aggressive.
Entry: Sustained close above the horizontal resistance.
Bullish
Cup and Handle
Structure: Rounded bottom (cup) followed by a small dip (handle).
Context: Often found on 5-minute or 15-minute charts after a major run.
Risk: Stop loss placed at the bottom of the handle.

Bearish Continuation Patterns

For short-sellers or inverse ETF traders, bearish continuations provide entry points during downward "flushes." Momentum often accelerates faster to the downside due to the psychological impact of fear.

Bearish
The Bear Flag
Structure: Sharp vertical drop followed by an upward-sloping consolidation.
Entry: Break of the lower support line of the flag.
Risk: High probability of "trapping" late buyers.
Bearish
Descending Triangle
Structure: Horizontal support floor with lower highs pressing down.
Psychology: Buyers are defending a level, but demand is weakening.
Entry: Break of the horizontal support floor.
Pattern Verification: The 2-Bar Rule

A common error among beginners is "jumping the gun" before a pattern completes. To increase your win rate, utilize the 2-Bar Rule: wait for a 1-minute or 5-minute candle to close outside the pattern, and then wait for the following candle to break the high (for bull moves) or low (for bear moves) of that breakout candle. This filters out 40% of false breakouts.

Major Structural Reversals

Reversals occur when a trend has reached exhaustion. These patterns often take longer to form and represent a total shift in institutional sentiment.

Structure: Left Shoulder, Head (higher peak), and Right Shoulder. The "Neckline" connects the lows.

The Reversal Signal: A break of the neckline indicates that the uptrend has failed to make a new high and has subsequently lost its primary support level. The "Inverse Head and Shoulders" is the bullish equivalent found at market bottoms.

Psychology: A Double Top occurs when price hits a resistance level twice and fails to break through. It signals that buyers have exhausted their capital at that specific valuation.

Tactical Note: Look for a "Divergence" in the RSI (Relative Strength Index) during the second peak. If the second peak has a lower RSI than the first, the reversal probability is extreme.

The Mathematics of Price Targets

Professionalism in pattern trading requires objective exit targets. We use the "Measured Move" approach to calculate where price is likely to travel after a breakout.

The Measured Move Calculation (Triangle)
Triangle Height (Base): 2.50 dollars
Breakout Entry Price: 45.00 dollars
Stop Loss (Pattern Midpoint): 44.20 dollars
Risk Amount: 0.80 dollars
Technical Target (Entry + Height): 47.50 dollars
Reward-to-Risk Ratio: 3.12 : 1

By quantifying the target before entry, you can ensure that the trade meets your minimum risk-to-reward requirements (typically 2:1 or higher). If a pattern is too small or the volatility too high, the math will dictate that the trade should be rejected, regardless of how "good" the chart looks.

Reliability and Volume Confirmation

Not all patterns carry the same statistical weight. The reliability of a formation is directly proportional to the Timeframe and the Volume Signature.

Chart Pattern Average Win Rate Ideal Volume Signature Best Timeframe
Bull Flag 65% - 70% Surge on Pole, Dry on Flag 1-Min / 5-Min
Double Bottom 60% - 65% Increase on second bounce 15-Min / 60-Min
Head and Shoulders 55% - 60% Heavy volume on Left/Head Daily / 60-Min
Symmetrical Triangle 50% (Neutral) Expansion on breakout Any
Ascending Triangle 70% plus Consistent buying pressure 5-Min / 15-Min

Integrating Patterns into Execution

Success requires the integration of these patterns into a broader Workflow. A pattern should never be traded in isolation. It must be filtered through market context.

  • Macro Filter: Is the S&P 500 (SPY) trending in the same direction as your pattern?
  • Relative Strength: Is your stock gapping up or showing higher volume than its peers?
  • Order Flow: Does the Level 2 show a "Hidden Bid" supporting your pattern floor?

In final synthesis, the patterns on this cheat sheet are your tools for navigating market entropy. They provide the structure necessary to transform a chaotic stream of prices into a systematic business of probability. Respect the breakout, verify the volume, and manage the risk with mathematical severity. The patterns will repeat as long as humans trade markets, but only the disciplined will be there to profit from them.
