SignalScan PRO User Guide Back to Scanner

SignalScan PRO is a real-time U.S. stock market scanner designed to identify high-probability trading opportunities across multiple specialized channels. Each channel is a focused "lens" that monitors specific price, volume, and volatility conditions and displays only the symbols that currently meet those criteria.

Channels Covered:
1. PreGap Channel

1.1 Purpose

The PreGap channel highlights stocks that are significantly gapping up or down in pre-market trading compared to the prior session's close. These gaps often signal catalysts such as earnings, guidance changes, sector news, or macro events and are a core source of day-trading opportunities.

1.2 Typical Columns and What They Mean

1.3 How to Use PreGap in Practice

When to Watch It: Best used between 4:00–9:30 AM ET, when pre-market activity develops, and near the open as volume surges.

What to Look For:

Common Uses:

  1. Build a Morning Watchlist: Filter by minimum price (e.g., $5+), minimum pre-market volume, and Gap %. Prioritize symbols with both a large gap and high RVOL.
  2. Plan Scenarios Before the Open: Where is the pre-market high/low vs. prior day high/low? Are you interested in gap-and-go (continuation beyond pre-market levels) or gap fill (reversion back toward prior close)?
  3. Risk Management from Pre-Market Structure: Use pre-market low (for longs) or pre-market high (for shorts) as initial risk reference once regular hours begin.
2. HOD Channel (High of Day)

2.1 Purpose

The HOD channel tracks stocks that are printing new intraday highs, signalling strong buying interest and potential breakout/continuation opportunities. It is particularly valuable for identifying afternoon breakouts and all-day trend stocks.

2.2 Typical Data Fields

2.3 How to Use HOD

Key Concepts: A new high of day is a breakout of intraday resistance. As price clears that level, it can trigger momentum traders entering, short sellers covering, and algorithms chasing strength.

Practical Applications:

  1. Momentum Continuation Trades: Look for symbols making multiple HOD prints with rising volume and RVOL > 1.5–2.0. Enter on pullbacks near prior HOD levels, which may act as new support.
  2. Afternoon Breakouts (PDT-Friendly): Many intraday traders focus on HOD scans in the afternoon (e.g., after 1:30–2:00 PM); breakouts here can trend into the close or gap the following day.
  3. Avoiding Bull Traps: HOD breaks without volume confirmation are vulnerable to sharp reversals (bull traps). Always confirm with RVOL and candle structure; avoid chasing extended moves on low volume.
3. RunUp Channel

3.1 Purpose

RunUp captures rapid, short-term price accelerations—stocks that have moved significantly within a short recent window (e.g., last 1–5 minutes). It's a pure momentum "heat-seeker."

3.2 Typical Data Fields

3.3 How to Use RunUp

Main Use Case - Scalping and Fast Momentum:

Entry Approaches:

Combining with Other Channels: The best RunUp candidates often also appear on HOD or ORB and have a supportive Trend reading (uptrend for longs). Multi-channel alignment increases probability.

4. Rvsl Channel (Reversals)

4.1 Purpose

The Rvsl channel is built to identify potential turning points—stocks that may be reversing after an extended move, often based on overbought/oversold and divergence logic.

4.2 Typical Data Fields

4.3 How to Use Rvsl

Bullish Reversal Setups - Look for:

You might enter when price reclaims a key level (e.g., reclaim of VWAP or a support line) with improving momentum and volume.

Bearish Reversal Setups - Look for:

Important Notes: Reversal trading is inherently counter-trend and can be higher risk if you're early. Consider smaller size, tighter stops, and wait for confirmation.

5. ORB Channel (Opening Range Breakout)

5.1 Purpose

ORB (Opening Range Breakout) focuses on breakouts of the initial range formed shortly after the open (commonly the first 5, 15, or 30 minutes). It is a widely used intraday strategy.

5.2 Typical Data Fields

5.3 How to Use ORB

Core Concept:

  1. Define opening range (e.g., first 15 minutes).
  2. Wait for price to break above the ORB High (long) or below the ORB Low (short) with strong volume.
  3. Trade in the direction of the breakout.

Practical Tips:

6. Vector Channel

6.1 Purpose

The Vector channel is about volume–price "climax" areas, or "vector zones," where volume and candle range spike significantly, often marking key support/resistance that price later revisits. It's loosely based on Price–Volume–Support/Resistance Analysis (PVSRA).

6.2 Typical Data Fields

6.3 How to Use Vector

Concept: Vector events indicate zones of heavy institutional activity. Markets tend to revisit these zones because they represent incomplete orders or large positioning.

Example Uses:

Use clear stops just beyond the zone and targets at adjacent technical levels or other vector zones.

7. Squeeze Channel

7.1 Purpose

The Squeeze channel identifies periods where volatility compresses ("the coil") followed by explosive expansions when the squeeze "fires." This is often built around the TTM Squeeze logic—Bollinger Bands relative to Keltner Channels.

7.2 Typical Data Fields

7.3 How to Use Squeeze

Squeeze ON (Compression): Bollinger Bands inside Keltner Channels = volatility is very low. The longer the squeeze lasts, the more powerful the eventual move tends to be when it fires.

Squeeze OFF (Release): When status flips to OFF, the move is "released" and volatility expands. Your job: trade in the direction of confirmed momentum.

Basic Trading Playbook:

  1. Scan for Squeeze ON stocks with several bars of compression.
  2. Watch momentum histogram: If it is rising and above zero, bias is bullish. If it is falling and below zero, bias is bearish.
  3. Enter when squeeze changes from ON → OFF in the direction of histogram.
  4. Place stop on the opposite side of the recent range or Keltner Channel.

Multi-Timeframe Edge: Strongest moves often occur when Daily, 60-min, and 5-min all had squeezes that fire in the same direction. Combining Squeeze with ORB or Trend channels can significantly improve signal quality.

8. Trend Channel

8.1 Purpose

The Trend channel provides a higher-level, multi-timeframe view of trend direction and strength, helping you align trades with broader forces instead of fighting them.

8.2 Typical Data Fields

8.3 How to Use Trend

For Longs (Uptrend) - Look for:

Enter on pullbacks to support or MAs rather than at extended highs.

For Shorts (Downtrend) - Look for the opposite:

Timeframe Alignment: When intraday, swing, and higher timeframe all align, probabilities increase dramatically. Use Trend as a "filter" so you only take ORB, HOD, RunUp, Squeeze, or Rvsl trades that agree with the dominant trend.

Divergence Warnings: Trend tools sometimes flag regular or hidden divergence between price and momentum. Regular divergence may signal trend exhaustion and possible reversal. Hidden divergence often suggests continuation after a correction.

9. Integrating the Channels

9.1 Multi-Channel Confirmation

The strongest opportunities tend to trigger across several channels at once:

Use the scanner as an idea generator, then confirm entries with your charting and rules.
