Pre-built Strategy Scanners

Pre-built Strategy Scanners are designed to help traders quickly identify high-potential trading opportunities without constant market monitoring. Once deployed, these scanners continuously analyze selected assets in real time, tracking price action, volume, and technical conditions.


1. Harmonic Pattern Scanners

Harmonic Pattern Scanners identify advanced price structures based on Fibonacci ratios to detect potential market reversals.

  • Gartley – Harmonic Pattern Scanner: Identifies harmonic price structures based on the classic X-A-B-C-D formation.
  • Shark – Harmonic Pattern Scanner: Detects a five-leg structure (O-X-A-B-C) that differs from traditional XABCD patterns.
  • Deep Crab – Harmonic Pattern Scanner: Identifies an advanced harmonic structure characterized by a very deep retracement followed by a large Fibonacci extension.
  • Cypher – Harmonic Pattern Scanner: Detects a modern harmonic pattern defined by asymmetrical leg relationships and strict Fibonacci dependencies.
  • Crab – Harmonic Pattern Scanner: Identifies harmonic patterns that feature deep Fibonacci extensions, particularly at the final leg.
  • Butterfly – Harmonic Pattern Scanner: Detects patterns where the final structure extends beyond the starting point of the pattern.
  • Bat – Harmonic Pattern Scanner: Identifies harmonic patterns with shallower retracements and a deeper completion level compared to Gartley.

2. Chart Pattern Scanners

Chart Pattern Scanners focus on classical price formations that indicate trend continuation or reversal.

  • Bear Flag – Chart Pattern Scanner: Detects bearish continuation patterns formed after sharp declines, signaling potential downside breakouts following consolidation.
  • Bear Pennant – Chart Pattern Scanner: Identifies bearish pennant formations that suggest continuation of a downtrend after a brief consolidation phase.
  • Bull Flag – Chart Pattern Scanner: Scans for bullish flag patterns that indicate potential upside continuation after strong upward price movements.
  • Bull Pennant – Chart Pattern Scanner: Detects bullish pennant formations signaling possible upward breakouts following consolidation.
  • Head & Shoulders – Chart Pattern Scanner: Identifies head and shoulders patterns that signal potential bearish trend reversals after an uptrend.
  • Inverse Head & Shoulders – Chart Pattern Scanner: Scans for inverse head and shoulders patterns that indicate potential bullish reversals after a downtrend.

3. Momentum Scanners

Momentum Scanners identify strong price movements supported by volume and momentum indicators.

  • MACD Signal – Momentum Scanner: Detects MACD signal line crossovers to identify potential shifts in price momentum.
  • Price Breakout – Momentum Scanner: Identifies price movements beyond key support or resistance levels, signaling the start of a potential new trend.
  • ROC Volume Breakout – Momentum Scanner: Uses the Rate of Change (ROC) indicator combined with volume analysis to detect accelerating price momentum.
  • Stochastic Breakout – Momentum Scanner: Scans for Stochastic RSI breakouts beyond overbought or oversold levels, signaling potential price reversals or continuations.
  • Volume Breakout – Momentum Scanner: Detects breakouts confirmed by increased trading volume, improving the reliability of breakout signals.
  • Volume & EMA Breakout – Momentum Scanner: Identifies breakouts where price crosses key exponential moving averages (EMA) supported by strong volume.

4. Crossover Scanners

Crossover Scanners track indicator crossovers, which often signal trend changes.

  • Bollinger Cross – Crossover Scanner: Identifies price crossovers above or below the Bollinger Bands’ middle line, signaling potential trend continuation or reversal.
  • Death Cross – Crossover Scanner: Detects bearish crossovers where a short-term moving average crosses below a long-term moving average.
  • Golden Cross – Crossover Scanner: Identifies bullish crossovers where a short-term moving average crosses above a long-term moving average.
  • MACD Crossover – Crossover Scanner: Scans for MACD line crossovers with the signal line, indicating changes in market momentum.
  • Parabolic SAR Cross – Crossover Scanner: Detects Parabolic SAR position changes relative to price, signaling potential trend reversals.
  • Short Uptrend – Crossover Scanner: Identifies short-term upward trends using trend confirmation tools such as moving averages or trendlines.

5. Running a Scanner

To activate a scanner, follow these steps:

  1. Click Run Scan on the desired scanner.
  2. Select assets and timeframe for analysis.
  3. The Scanner continuously monitors markets in real time.
  4. Results highlight assets matching the specific scanner criteria.

Key Benefits

  • No manual monitoring required: Automated systems do the heavy lifting.
  • Real-time market analysis: Capture moves as they happen.
  • Broad Strategy Coverage: Covers harmonic, chart, momentum, and crossover types.
  • Idea Generation: Ideal for finding new trade setups and strategy building.

⚠️ Please Note

The “Run Scan” feature should not be interpreted as a backtesting tool. Instead, it functions as a real-time (forward-testing) scanner that continuously monitors the market for patterns as new data arrives.

When users observe patterns directly on charts, they are typically analyzing historical data, which effectively serves as a backtest. In this case, patterns are identified after they have fully formed, with the advantage of complete information.

Due to this key difference:

  • Run Scan → Forward Test (Real-Time Data)
  • Chart Analysis → Backtest (Historical Data)

Discrepancies between the two are normal and expected.

Real-time scanning operates under live market conditions, where patterns may still be forming and might not yet fully meet all criteria. On the other hand, historical chart analysis benefits from hindsight, where patterns are already complete and clearly visible.
