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.
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
- Symbol: Ticker being scanned.
- Last / Pre-Mkt Price: Current pre-market trading price.
- Gap %: Percent difference between yesterday's close and current pre-market price. Gap % = (Pre-Mkt Price – Prior Close) / Prior Close × 100.
- Gap Direction: Up (positive) or Down (negative).
- Volume / Pre-Mkt Volume: Number of shares traded pre-market.
- RVOL (Relative Volume): Current volume relative to the average volume at this same time of day; RVOL = 2.0 means twice the typical volume.
- Float: Shares freely available to the public; low float names tend to move more sharply on news.
- Price Bands / Levels: Reference levels such as prior day high/low, pre-market high/low, or calculated support/resistance.
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:
- Gap % ≥ 5% with RVOL ≥ 2.0: Indicates meaningful gap with real liquidity, not just a few thin prints.
- Gap Up + High RVOL + News: Classic recipe for a potential trend or momentum play after the open.
- Gap Down + High RVOL: Often associated with negative news; can be candidates for short setups or oversold reversals depending on intraday structure.
Common Uses:
- 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.
- 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)?
- 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
- Symbol: Ticker.
- HOD Price: Current high-of-day price.
- Time of HOD: Timestamp when the HOD was last set.
- % Change: Percent change from the prior close.
- Volume / Intraday Volume: Volume since the open.
- RVOL: Intraday relative volume.
- Distance to HOD: How far current price is from HOD (useful if you're waiting for a retest).
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:
- 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.
- 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.
- 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
- Symbol
- Short-Term % Change: Price change over the scanner's lookback (e.g., 1–5 minutes).
- Current Price
- Volume Spike: Volume in the last bar vs recent bars.
- RVOL
- Time: Timestamp of the spike.
3.3 How to Use RunUp
Main Use Case - Scalping and Fast Momentum:
- Focus on symbols showing short-term % change ≥ ~2% in 5 minutes, clear volume spike, and RVOL ≥ 2.0.
Entry Approaches:
- Don't chase the spike candle itself. Wait for a small pullback to the 9/20 EMA on your intraday chart, or a brief consolidation just under recent highs.
- Use tight stops since these moves can reverse quickly.
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
- Symbol
- Reversal Type: Bullish (oversold bounce) or Bearish (overbought fade).
- Signal Strength / Score: Quality rating of the setup.
- RSI / Other Oscillator: Indicates overbought (>70) or oversold (<30) conditions.
- Divergence: Flags when price and momentum are moving in opposite directions.
- Price
4.3 How to Use Rvsl
Bullish Reversal Setups - Look for:
- Extended down move.
- RSI or similar indicator below 20–30.
- Bullish divergence (price making lower lows while RSI makes higher lows).
- Defined support zone (prior lows, volume shelf, etc.).
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:
- Extended up move.
- RSI above 70–80.
- Bearish divergence (price higher highs, momentum lower highs).
- Signs of exhaustion (long top wicks, fading volume).
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
- Symbol
- ORB High / ORB Low: High and low of the selected opening range window.
- Range Width: High–low distance in dollars or %.
- Entry Price: Ideal breakout level determined by the system.
- Target: Typically 1–2× the range width.
- Stop Loss: Often on the opposite side of the range.
5.3 How to Use ORB
Core Concept:
- Define opening range (e.g., first 15 minutes).
- Wait for price to break above the ORB High (long) or below the ORB Low (short) with strong volume.
- Trade in the direction of the breakout.
Practical Tips:
- Favor symbols with good liquidity (volume, tight spreads), RVOL ≥ 2.0, and clean ORB structure (no excessive whipsaws inside that first range).
- Entry: Either on the breakout candle itself, or better: on a pullback to the ORB line when it holds as support/resistance.
- Exits: Use tool-provided Target and Stop as baselines; consider partial profit at 1R and further profit at 2R+.
- Timeframe Choice: 5-min ORB for very active, volatile names. 15–30 min ORB for more stable, higher-cap stocks.
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
- Symbol
- Vector Type: Climactic (large volume and big candle range, e.g., >200% of recent average), or Above-average (still notable, but less extreme).
- Vector Color: Green = Bullish climactic, Red = Bearish climactic, Blue/Violet = Above-average variants.
- Vector Price Zone: Price area where the vector was formed.
- Recovery %: How much of that vector zone has been revisited ("filled") by price.
- Volume Multiple: Multiplier vs average volume (e.g., 2×, 3×).
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:
- Support/Resistance Bounces: Price initially moves away from a vector zone, then later returns. Traders often look to enter in the zone expecting it to act as support (for bullish vectors) or resistance (for bearish vectors).
- Recovery % as a Timing Tool: 0%: Not revisited yet; watchlist for future retest. Partial (e.g., 50%): In progress. 100%: Fully revisited; zone may now complete its role.
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
- Symbol
- Squeeze Status: ON (compression) or OFF (fired).
- Momentum Histogram: Direction and strength of momentum (above/below zero, rising/falling).
- Histogram Color: Cyan/light blue for strengthening bullish, red/dark for strengthening bearish.
- Squeeze Duration: Bars spent in squeeze.
- Expected Direction: Derived from the histogram trend.
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:
- Scan for Squeeze ON stocks with several bars of compression.
- Watch momentum histogram: If it is rising and above zero, bias is bullish. If it is falling and below zero, bias is bearish.
- Enter when squeeze changes from ON → OFF in the direction of histogram.
- 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
- Symbol
- Trend Direction: Up, Down, or Neutral.
- Trend Strength (0–100): Higher = more robust, established trend.
- Timeframe Alignment: Percentage of timeframes (e.g., daily, 4h, 1h, 15m) all pointing in same direction.
- Confidence (0–100%): Model confidence in its assessment.
- Signal: e.g., BUY, SELL, HOLD.
- Moving Average Position: Price relative to important MAs (50, 200, etc.).
8.3 How to Use Trend
For Longs (Uptrend) - Look for:
- Trend Direction = UP.
- Trend Strength ≥ ~70.
- Confidence ≥ ~70%.
- Price above 50 MA; 50 MA above 200 MA (classic uptrend stack).
- Higher highs and higher lows visible in swing structure.
Enter on pullbacks to support or MAs rather than at extended highs.
For Shorts (Downtrend) - Look for the opposite:
- Trend Direction = DOWN.
- Trend Strength ≥ ~70.
- Confidence ≥ ~70%.
- Price below 50 MA; 50 MA below 200 MA.
- Lower highs and lower lows.
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:
- PreGap + ORB + Trend UP + Squeeze firing up = high-quality long candidate.
- Extended run + Rvsl Bearish + Squeeze firing down + Trend weakening = potential short/mean-reversion setup.
Use the scanner as an idea generator, then confirm entries with your charting and rules.
9.2 Universal Filters
- RVOL ≥ 2.0: Confirms that moves are accompanied by above-normal participation.
- Liquidity: Favor symbols with tight spreads and decent average daily volume.
- Float Awareness: Low-float names are more dangerous and require smaller size and wider stops.
