HTF Open Cross — Multi-Symbol Scanner V2

The HTF Open Cross — Multi-Symbol Smart Scanner is a professional-grade dashboard that continuously monitors up to 20 instruments for lower-timeframe (LTF) price crosses relative to their higher-timeframe (HTF) open.

Each detected signal represents a momentum confirmation — when a lower timeframe candle closes beyond the HTF open by a configurable Z-threshold in pips, in alignment with the previous HTF candle bias (bullish or bearish).

🔍 Key Features

📊 Multi-Instrument Scan: Evaluate up to 20 tickers simultaneously, with independent LTF/HTF pairings.

⏰ Active Signal Tracking: Displays only signals fired within a user-defined expiry window (e.g., last 10 minutes).

🧭 Session-Aware Filtering: Signals are valid only during active market sessions (customizable).

🧮 Auto Pip Detection: Automatically detects appropriate pip scaling for FX and JPY pairs.

🧱 Zebra Table Bands: Alternating row colors for visual clarity.

🔄 Smart Sorting: Arrange the dashboard by LONGs first, expiry soonest, or expiry latest.

⏳ Countdown Timer: Each signal shows remaining time until expiry for fast decision-making.

🎯 Real-Time Bias View: See at a glance which markets are currently biased LONG or SHORT relative to their HTF opens.

⚙️ How It Works

The script calls request.security() to fetch HTF and LTF data for each symbol.

It detects cross conditions:

LONG = previous HTF bullish + LTF close ≥ HTF open + threshold

SHORT = previous HTF bearish + LTF close ≤ HTF open − threshold

Each signal is timestamped, age-filtered, and stored in sortable arrays.

The table dashboard refreshes dynamically to show only active signals, color-coded and ranked.

🧭 Use Cases

Identify when momentum aligns across multiple instruments.

Spot early bias shifts between sessions.

Create alerts for systematic scalping or bias confirmation models.
