Core Analysis Methods

1. Classic Pivot Points - The Foundation of Technical Analysis

Method: pivot_points Purpose: Calculate traditional pivot points based on previous period's high, low, and close prices. Pivot points are widely used by traders to identify key support and resistance levels for the upcoming trading session. These levels act as psychological barriers where buying and selling pressure tends to converge, making them excellent reference points for entry, exit, and stop-loss placement strategies.

Formula Overview:

  • Pivot (P): (High + Low + Close) / 3
  • Resistance 1 (R1): (2 × P) - Low
  • Support 1 (S1): (2 × P) - High
  • Resistance 2 (R2): P + (High - Low)
  • Support 2 (S2): P - (High - Low)

Example - Daily Pivot Points:

  • rowsExpr: vars.daily_ohlc_data (expression returning OHLC data)
  • open: open (column name for open prices)
  • high: high (column name for high prices)
  • low: low (column name for low prices)
  • close: close (column name for close prices)
  • methods: ["pivot_points"] (analysis methods to use)
  • lookback_period: 20 (period for analysis)

Output:

  • support_levels: Dictionary with support levels (sr_s1, sr_s2, sr_s3)
  • resistance_levels: Dictionary with resistance levels (sr_r1, sr_r2, sr_r3)
  • current_price: Current closing price for reference
  • nearest_support: Closest support level below current price
  • nearest_resistance: Closest resistance level above current price
  • price_position: Relative position between nearest S/R levels (0-1 scale)

2. Woodie Pivot Points - Enhanced Weighting

Method: pivot_woodie Purpose: Calculate Woodie pivot points, a modified version of traditional pivot points that gives more weight to the closing price. This method is particularly effective in trending markets where the closing price carries significant information about market sentiment and momentum. Woodie pivots provide more responsive levels that better reflect current market conditions compared to classic pivots.

Key Differences from Classic:

  • Pivot (P): (High + Low + 2 × Close) / 4
  • Better suited for trending markets
  • More responsive to recent price action

Example - Woodie Calculation:

  • methods: ["pivot_woodie"] (use Woodie pivot method)
  • rowsExpr: data.price_data (expression with price data)

3. Camarilla Pivot Points - Intraday Precision

Method: pivot_camarilla Purpose: Calculate Camarilla pivot points, an advanced pivot system specifically designed for intraday trading and scalping strategies. Unlike traditional pivots, Camarilla levels are calculated using a unique formula that creates tighter ranges around the current price, making them ideal for short-term traders who need precise entry and exit points within a single trading session.

Unique Features:

  • 8 Levels: S1-S4 support and R1-R4 resistance levels
  • Tighter Ranges: More precise levels for scalping and day trading
  • L3/L4, H3/H4: Extreme levels often act as major reversal points

Example - Camarilla Levels:

  • methods: ["pivot_camarilla"] (use Camarilla pivot method)
  • rowsExpr: vars.intraday_data (expression with intraday OHLC data)

Output:

  • support_levels: Camarilla support levels (camarilla_support_1 through camarilla_support_4)
  • resistance_levels: Camarilla resistance levels (camarilla_resistance_1 through camarilla_resistance_4)

4. Fibonacci Retracement - Golden Ratio Analysis

Method: fibonacci_retracement Purpose: Calculate Fibonacci retracement levels based on recent price swings using the mathematical golden ratio sequence. These levels help identify potential reversal points during price corrections within a larger trend. Fibonacci retracements are particularly powerful because they combine mathematical precision with market psychology, creating levels where traders naturally place orders.

Fibonacci Ratios Used:

  • 0.236 (23.6%): Shallow retracement, often weak support/resistance
  • 0.382 (38.2%): Common retracement level, moderate strength
  • 0.5 (50.0%): Psychological midpoint, strong level
  • 0.618 (61.8%): Golden ratio, very strong level
  • 0.786 (78.6%): Deep retracement, potential reversal zone

Example - Fibonacci Analysis:

  • methods: ["fibonacci_retracement"] (use Fibonacci retracement method)
  • lookback_period: 50 (period for swing analysis)
  • rowsExpr: data.historical_prices (expression with historical OHLC data)

Output:

  • support_levels: Fibonacci support levels (fib_0.786_support, fib_0.618_support, fib_0.5_support)
  • resistance_levels: Fibonacci resistance levels (fib_0.382_resistance, fib_0.236_resistance)

5. Fibonacci Extensions - Projection Targets

Method: fibonacci_extensions Purpose: Calculate Fibonacci extension levels that project potential price targets beyond the current swing range. These levels help traders identify where a trend might continue after breaking through previous highs or lows, providing objective profit targets and continuation pattern recognition. Extensions are essential for position traders who need to set realistic price objectives.

Extension Ratios:

  • 1.272: First extension target
  • 1.618: Golden ratio extension (primary target)
  • 2.0: 100% extension (secondary target)
  • 2.618: Extended target for strong trends

Example - Extension Targets:

  • methods: ["fibonacci_extensions"] (use Fibonacci extensions method)
  • fib_ext_ratios: "1.272,1.618,2.0,2.618" (comma-separated extension ratios)
  • rowsExpr: vars.swing_data (expression with swing data)

6. Technical Analysis Extrema - Advanced Swing Detection

Method: ta_extrema Purpose: Identify local maxima and minima (swing highs and lows) using advanced signal processing algorithms. This method automatically detects significant turning points in price action, creating support and resistance levels based on actual market behavior rather than mathematical formulas. It's particularly valuable for swing traders who want to focus on levels that have proven their significance through price action.

Algorithm Features:

  • Scipy Signal Processing: Uses argrelextrema for precise swing detection
  • Order Parameter: Controls sensitivity (higher = fewer, stronger levels)
  • ATR Clustering: Groups nearby levels into consolidated zones
  • Top N Selection: Returns most significant levels

Example - Advanced Swing Analysis:

  • methods: ["ta_extrema"] (use technical analysis extrema method)
  • order: 5 (extrema sensitivity parameter)
  • atr_mult: 1.5 (ATR multiplier for clustering)
  • top_n: 8 (maximum number of levels to return)
  • lookback_bars: 100 (number of bars to analyze)

7. Price Channels (Donchian) - Trend Channel Analysis

Method: price_channels Purpose: Calculate Donchian price channels (also known as trading ranges) that show the highest high and lowest low over a specified period. These channels help identify trending markets and potential breakout opportunities. When price consistently hugs one side of the channel, it indicates a strong trend, while breakouts from the channel can signal major trend changes or continuation moves.

Channel Components:

  • Upper Channel: Highest high over period
  • Lower Channel: Lowest low over period
  • Mid Channel: Midpoint for additional context

Example - Channel Analysis:

  • methods: ["price_channels"] (use price channels method)
  • channel_length: 20 (lookback period for channel calculation)
  • rowsExpr: data.price_series (expression with price data)

8. Psychological Price Levels - Round Number Analysis

Method: psychological_levels Purpose: Identify psychological price levels based on round numbers that act as significant psychological barriers in traders' minds. These levels (like 100, 1000, 5000, etc.) often cause hesitation or increased activity because they represent clean, easy-to-remember price points. Psychological levels can be more significant than technical levels because they influence the collective behavior of market participants.

Features:

  • Auto Step Detection: Automatically determines appropriate step size
  • Custom Steps: Manual step configuration for specific assets
  • Multi-Level: Generates multiple levels around current price

Example - Psychological Levels:

  • methods: ["psychological_levels"] (use psychological levels method)
  • psych_step: 0 (step size, 0 = auto-detect)
  • psych_count: 3 (number of levels per side)

Output:

  • support_levels: Psychological support levels (psych_0, psych_1, psych_2)
  • resistance_levels: Psychological resistance levels (psych_0, psych_1, psych_2)
