Daily High/Low probability zonesDaily High/Low probability zones
Overview
Daily Segment Probabilities analyses the statistical distribution of where a market forms its daily High and daily Low relative to the previous session's range. By studying the prior day's High (PDH) and Low (PDL) across a user-defined lookback window, the indicator divides the price space around that range into 12 equal segments of 25% each — from −100% to +200% — and calculates how frequently the current session's High and Low have historically landed inside each segment. The result is a probability map drawn directly on the chart for today's session, letting you see at a glance which zones have historically attracted the day's extremes.
What is shown on the chart
The PDH and PDL of the prior session are drawn as solid horizontal lines across the current day, labelled in the margin. These form the 0% and 100% anchor points of the range.
Twelve segment boundaries are then projected from PDL upward and downward using the prior day's range as the measuring unit. Each boundary is coloured by zone: teal for the inside range (0–100%), indigo for upside extensions (above 100%), and red for downside extensions (below 0%). The 0% and 100% lines themselves are omitted from the segment boundaries since the PDH/PDL lines already mark them.
At the midpoint of each band, a label shows the segment name alongside the historical probability of the day's High and Low forming within that band — for example 0–25% H:18% L:34%. A tooltip on each label gives the full count of occurrences out of total sample days.
The two highest-probability bands are highlighted with a filled overlay: a gold fill marks the segment where the day's High has most frequently formed, and an orange fill marks the segment where the day's Low has most frequently formed. These fills are also reflected in the probability table — the High% and Low% cells for the top segments are coloured to match, creating a direct visual link between the chart and the table. Labels for the top bands carry a ★H or ★L marker for quick identification.
The probability table
The table summarises the full segment distribution in a compact grid with four columns:
Seg — segment number (1–12, top to bottom of chart)
Range — the percentage band that segment covers
High% — percentage of historical days where the session High formed in this segment
Low% — percentage of historical days where the session Low formed in this segment
Below the twelve data rows is an OOB (out-of-bounds) row counting days where the High or Low fell completely outside the −100% to +200% window. The footer row shows the actual sample size (n) and the configured lookback.
The High% and Low% cells for the two top-probability segments are highlighted with the same fill colours used on the chart, so the table and the chart read as a unified system.
How the lookback and calculation work
The lookback setting (default 250 days, range 10–500) defines how many prior daily sessions are included in the historical sample.
For each day in that window the indicator:
Takes the prior session's High and Low to establish the reference range and its 0% / 100% anchors.
Measures where that session's own High and Low fell, expressed as a percentage of the prior range above the prior Low — so a High exactly at the PDH of its own prior session registers as 100%, and a Low exactly at the PDL registers as 0%.
Assigns each reading to whichever 25%-wide segment it falls into.
Counts occurrences per segment across all n valid days (days where the prior range is greater than zero are included; zero-range days are skipped).
Probabilities in the table and labels are the count for each segment divided by n, rounded to the nearest whole percent. The top-segment fills and ★ markers are determined purely by the highest raw count, not the rounded percentage, so ties resolve correctly.
A minimum of 5 valid days is required before anything is drawn.
Settings
Core Settings
Lookback (days) — number of prior sessions used to build the probability distribution. Higher values give a more statistically stable sample; lower values are more responsive to recent market character. 250 days (roughly one trading year) is a reasonable default for most instruments.
Visual Settings
PDH/PDL line colour — colour of the prior day High and Low anchor lines.
Inside range colour (0–100%) — colour applied to segment boundaries within the prior range.
Extension above colour (>100%) — colour for boundaries above the PDH.
Extension below colour (<0%) — colour for boundaries below the PDL.
Label text colour — colour of the midpoint probability labels.
Segment line style — Solid, Dotted, or Dashed for segment boundaries.
PDH/PDL line style — Solid, Dotted, or Dashed for the anchor lines.
Top High% band fill colour — fill colour for the highest-probability High segment (default gold).
Top Low% band fill colour — fill colour for the highest-probability Low segment (default orange).
Table Settings
Show probability table — toggle the table on or off.
Table position — Top Right, Bottom Right, Middle Right, Bottom Center, or Middle Left.
Table text size — Auto, Tiny, Small, Normal, Large, or Huge.
Interpreting the output
The indicator does not predict where price will go — it describes where it has historically gone. A segment showing H:35% means the day's High landed in that band on roughly one in three days over the lookback period. Used alongside other context (session opens, market structure, news), the distribution can inform expectations for the day's likely trading range and where extension targets have historically clustered.
Segments inside the prior range (0–100%) capturing a high proportion of Low readings suggest mean-reversion sessions are common for the instrument. Large probabilities in extension segments (above 100% or below 0%) reflect trending or breakout tendencies. The OOB row is worth watching on highly volatile instruments where extreme moves regularly exceed the prior range by a wide margin.
Notes
The indicator is drawn only on the last bar of the chart to avoid repainting and to keep line/label counts within PulseWire's limits.
It is designed for use on intraday timeframes (1m–1h) where the daily session boundaries are visible. On a daily chart it will still compile but the lines will span only the current day's single candle.
The prior session data is fetched via request.security on the daily timeframe with lookahead_off to prevent look-ahead bias.
All percentages shown are based on historical frequency only and carry no implied forward guarantee. Indicator
4H HOD/LOD Checkpoint Analysis4H HOD/LOD Checkpoint Analysis - Detailed User Guide
OVERVIEW
This indicator is a data-driven probability framework for NQ Futures traders that predicts High-of-Day (HOD) and Low-of-Day (LOD) placement based on statistical analysis of 3,136+ trading days (2013-2025). Unlike traditional indicators that rely on technical signals, this tool uses checkpoint-based state analysis with zero forward-looking bias to provide real-time probabilities of whether the daily range is complete.
⚠️ IMPORTANT: This indicator is specifically designed for NQ FUTURES ONLY. All probabilities, patterns, and statistics were derived from a 10+ year historical dataset of NQ 1-minute bars. Using this on other instruments will produce inaccurate results.
CORE CONCEPT: CHECKPOINT METHODOLOGY
What is a Checkpoint?
A checkpoint occurs when a 4-hour candle closes. At this moment, the indicator "locks" the current market state and calculates probabilities for the remainder of the trading day. The key innovation is that state never changes after locking - probabilities remain constant throughout the session until the next checkpoint.
The Six 4-Hour Candles (EST):
6PM (18:00-22:00) - Evening/Globex open
10PM (22:00-02:00) - Asia session
2AM (02:00-06:00) - Early London
6AM (06:00-10:00) - Late London + NY Open
10AM (10:00-14:00) - NY Morning
2PM (14:00-17:00) - NY Afternoon (3 hours only)
Five Checkpoints:
10PM Checkpoint - After 6PM closes
2AM Checkpoint - After 10PM closes
6AM Checkpoint - After 2AM closes
10AM Checkpoint - After 6AM closes (most critical)
2PM Checkpoint - After 10AM closes (highest conviction fade signals)
HOW IT WORKS: THE THREE-FACTOR STATE SYSTEM
At each checkpoint, the indicator evaluates three critical factors to determine probability:
1. ELIMINATIONS (Quantity)
An "elimination" occurs when a candle trades beyond a previous candle's high or low, effectively removing that candle from contention for HOD/LOD.
Example at 10AM Checkpoint:
6PM high = 18,000
10PM high = 18,050 (eliminates 6PM high)
2AM high = 18,100 (eliminates 10PM high)
6AM high = 18,075 (does NOT eliminate 2AM high)
Result: 2 eliminations
The number of eliminations indicates trend strength:
0 eliminations = Range-bound, high probability extremes already set
1-2 eliminations = Moderate trend
3-4 eliminations = Strong trend day, range likely to extend
2. STRUCTURE (Pattern Type)
The indicator distinguishes between two elimination patterns:
Sequential: Eliminations occur in order (6pm → 10pm → 2am → 6am → 10am)
Indicates smooth, consistent trend
Example: 10pm eliminates 6pm, then 2am eliminates 10pm (sequential)
Skip: Eliminations skip candles
Indicates choppy/reversal behavior
Example: 2am eliminates 6pm but NOT 10pm (skip pattern)
Why it matters: Skip patterns show 2X probability differences compared to sequential patterns. At 10AM checkpoint with 2 eliminations, skip pattern shows 64% participation rate vs 36% for sequential pattern with previous survived.
3. PREVIOUS CANDLE STATUS
Did the immediately prior candle get eliminated?
Eliminated: Previous candle's high/low was taken out
Indicates relentless trend
Higher probability of continuation
Survived: Previous candle's high/low still intact
Indicates trend pause
Higher probability of mean reversion or range completion
Critical insight: High and low are tracked separately. At 2AM checkpoint, 10PM might have eliminated 6PM high (relentless uptrend) but NOT eliminated 6PM low (low survived). This creates different probabilities for HOD vs LOD.

Same for lows with 📉 symbol.
PRACTICAL TRADING EXAMPLES
Example 1: High Conviction Fade Setup
State at 10AM Checkpoint:
Eliminations: 0 (both HOD/LOD)
Structure: None (no eliminations yet)
Prev Candle: Survived
Table shows:
HOD Prob Already In: 68.9% (n=582)
LOD Prob Already In: 73.6% (n=785)
Interpretation: Range is likely complete. Fade extremes. With 0 eliminations and 70%+ probability, this is a high-conviction mean reversion signal.
Example 2: Strong Continuation Signal
State at 10AM Checkpoint:
Eliminations: 3 (both HOD/LOD)
Structure: Sequential
Prev Candle: Eliminated (relentless)
Table shows:
HOD Prob Already In: 29.8% (n=1,758)
LOD Prob Already In: 34.6% (n=1,451)
Pattern: 📈 Relentless / 📉 Relentless
Interpretation: Strong trend day. Only 30-35% chance range is complete. Look for breakouts in direction of trend. 10AM and 2PM likely to extend range.
Example 3: Pattern Structure Edge
State at 10AM Checkpoint:
Eliminations: 2 (HOD)
Structure: Skip (orange background)
Prev Candle: Eliminated vs Alternative State:
Eliminations: 2 (HOD)
Structure: Sequential
Prev Candle: Survived
Result: Skip pattern shows 64% chance 10AM participates vs 36% for sequential+survived. Skip pattern = 2X more likely to see 10AM high. This structural edge is unique to this indicator.
Example 4: Different HOD vs LOD Patterns
State at 10AM Checkpoint:
HOD: 2 eliminations, Sequential, Previous Eliminated (Relentless) = 46.7% in
LOD: 2 eliminations, Skip, Previous Eliminated (Choppy) = 48.4% in
Interpretation: Highs show relentless uptrend but lows show choppy behavior. This divergence suggests potential for upside continuation but with volatility. Not a clean trend day.
KEY CHECKPOINT STATISTICS (DERIVED FROM 10-YEAR DATASET)
10PM Checkpoint (After 6PM):
Very early in day
13.5% HOD in, 21.3% LOD in
Most likely outcome: Range extends into 6AM/10AM
2AM Checkpoint (After 10PM):
Still early
With 0 elims: 22-31% in (balanced)
With 1 elim: 8-12% in (strong trend signal)
6AM Checkpoint (After 2AM) - Critical Decision Point:
With 0 elims: 40-47% in (balanced, could go either way)
With 2 elims: 18-22% in (strong trend into 6AM/10AM)
Most likely outcome: 10AM sets extremes (~38-40%)
10AM Checkpoint (After 6AM) - Highest Conviction:
With 0 elims: 69-74% in → FADE (high confidence)
With 3 elims: 30-35% in → BUY/SELL continuation
This is THE money checkpoint for high-probability setups
2PM Checkpoint (After 10AM) - Maximum Fade Conviction:
With 0-3 elims: 67-95% in → FADE strongly
With 4 elims: 49-61% in (monster trend, weaker fade)
2PM is primarily a mean reversion session
UNDERSTANDING THE UNDERLYING DATA
All probabilities are derived from analysis of:
Instrument: NQ Futures (E-mini NASDAQ-100)
Timeframe: 1-minute bars
Period: January 2013 - December 2025
Sample: 3,136+ complete trading days
Methodology: Real-time checkpoint analysis with zero forward-looking bias
Why NQ-Specific?
Each futures contract has unique:
Session characteristics (6AM in NQ shows 60-64% curve behavior, other sessions differ)
Timing patterns (NQ's 10AM session has 67-74% immediate takeouts)
Volatility profiles (NQ 2PM shows 56% bullish bias vs ES shows different bias)
Using this indicator on ES, RTY, or other instruments will produce inaccurate results because the probability tables are NQ-specific.
ORIGINALITY & INNOVATION
What Makes This Indicator Unique:
Zero Forward-Looking Bias: State locks at checkpoint moments. Traditional indicators recalculate continuously, introducing bias. This indicator freezes probabilities at the exact moment a 4H candle closes.
Three-Factor State System: Combines elimination count, structure pattern, and previous candle status. Most indicators only track one dimension. This multi-factor approach provides 2X+ probability differentials.
Separate HOD/LOD Tracking: Highs and lows can have different patterns simultaneously (relentless high with choppy low). This indicator tracks them separately for precision.
Pattern Structure Analysis: Distinguishes between sequential and skip patterns, a concept not found in standard indicators. Skip patterns show mean reversion while sequential shows continuation.
10+ Year Statistical Foundation: Every probability is backed by hundreds to thousands of historical occurrences (sample sizes shown in table). Not based on theories or assumptions.
Checkpoint-Specific Probabilities: Different checkpoints have different probability profiles. 10AM checkpoint with 0 eliminations = 70%+ fade. 6AM checkpoint with same state = 40%+ fade. Context matters.
HOW TO USE THIS INDICATOR
Step 1: Wait for Checkpoint
The table will show "⏳ PRE-CHECKPOINT" until a 4H candle closes. Probabilities are only valid at checkpoint moments.
Step 2: Read the State
Check the three factors:
How many eliminations?
Sequential or skip?
Previous candle eliminated or survived?
Step 3: Check Probability
Look at "Prob Already In" percentage:
>75% (Green) = High confidence extreme is set, fade
45-75% (Yellow) = Moderate confidence, use other confirmation
<45% (Red) = Low confidence extreme is set, continuation likely
Step 4: Check Sample Size
Larger sample (n=1,000+) = higher confidence
Smaller sample (n=50-200) = use caution, edge is real but less robust
Step 5: Consider Pattern
Read the pattern guide:
Relentless = trend continuing
Paused = trend stalled, mean reversion
Skip/Chop = reversal/range likely
Step 6: Compare HOD vs LOD
If both show similar patterns = cleaner signal
If divergent patterns = complex day, be cautious
BEST PRACTICES
Focus on 10AM and 2PM checkpoints - These have the highest conviction signals
Combine with price action - Don't fade blindly at 90% probability if price is breaking out strongly
Larger samples = better edges - Prioritize setups with n=500+
Watch for pattern divergence - When HOD and LOD show different patterns, expect complexity
Remember session characteristics:
6AM = THE CURVE SESSION (60-64% mean reversion when Q2 breaks Q1)
10AM = THE MONEY SESSION (67-74% immediate takeouts, highest conviction)
2PM = THE FADE SESSION (67-95% extremes already in)

How to use:
It is important to note that using this indicator on it's own is not advisable. Instead, it should be combined with other tools and analysis for a more comprehensive trading strategy.
Possibly look to use my MTF Supply and Demand Indicator to look for zones to trade from at these levels?
If the price breaks above a high level, you might consider entering a long position, with the expectation that the price will continue to rise. Conversely, if the price breaks below a low level, you may think about entering a short position, anticipating further downward movement.
On the other hand, you can also use high or low levels to look for reversal trades, as these areas can represent attractive liquidity zones.
By identifying these key price points, you could take advantage of potential market reversals and capitalise on new trading opportunities.
Always remember to use this indicator in conjunction with other technical analysis tools for the best results.
Additionally, you can enable alerts to notify you when the price takes out high or low levels, helping you stay informed about significant price movements.
This indicator could be a valuable tool for traders looking to identify key price points for potential trading opportunities.
