SEIZ - Statistical External & Internal Zones [Pro]
Overview
SEIZ (Statistical External & Internal Zones) visualizes how far price typically travels beyond a prior candle’s range (external to previous candles high/low) or within it (internal to previous candles high/low).
It displays percentile thresholds that highlight when movement is statistically common vs. stretched relative to recent structure.
Key Features
• External zones: mark areas where price historically tends to extend beyond the previous range.
Example: a 50th external high percentile is a historically common extension above the prior candle range’s high; a 50th external low percentile is a historically common extension below the prior candle range’s low.
• Internal zones: mark areas where price historically tends to retrace while remaining inside the previous range.
Example: a 50th internal high percentile represents a historically common move that remained within the prior candle range on the high side; similarly for internal low.
• Auto-switching: When "enabled" the indicator will automatically switch to the correct internal or external zones. For example if the indicator is on the daily timeframe it will automatically show external high zones and levels if it has gone above the previous days high. It will then hide/filter out the internal high zones because price is no longer within the previous daily range.
• Multi-time-frame table: summarizes the most significant percentile reached on each enabled timeframe (e.g., 15m → 12h, 1D) with an interval-progress readout. For example if indicator is set to "Daily" it will show the highest level reached within the day under the "High" column, and the lowest level reached in the day under the "Low" column. The "Progress" column shows how much of the timeframe of that row has completed its candle/interval.
• Highly customizable settings:
- "Show Historic": When on will show current interval zones and as many previous intervals as possible
- "Show Intervals 2 Only": When on will show only the current and previous interval zones and levels.
- Choose between drawing lines for levels or zones or both. Customize colors and transparency of zones.
Methodology (transparency)
• SEIZ uses pre-computed, timeframe-specific percentile datasets that quantify typical extensions and retracements observed in historical data.
• The datasets are embedded in the script for deterministic plotting across timeframes; no external connections are used.
• Percentile values reflect empirical frequencies (not assumptions of a normal distribution).
• These levels do not have any prediction power over future price. They are a visual to compare historically where highs and lows most commonly formed for a time period with current price.
How to use
Choose the Timeframe to reference for zones.
Leave Auto external/internal zones filtering ON for regime-aware plotting.
Optional: enable percentile lines (25 / 50 / 75 / 85 / 95) and/or filled zones; adjust opacity and labels to taste.
Set alerts on percentile crosses to be notified when price reaches statistically rare areas.
Treat SEIZ as context; it does not generate entries or exits.
Notes
• Descriptive tool — no prediction or performance claims.
• Percentiles summarize historical behavior and can vary with market conditions.
• Source is protected to safeguard the proprietary construction of percentile datasets.
• Non-standard chart types (e.g., Heikin Ashi, Renko) are for display only.
