HUD lines & concepts

Reference

Every line that can appear on the ictru HUD, alphabetized with a one-line description and a link to the model it comes from. Plus a short glossary of the jargon.

updated 2026-04-24

The HUD paints predictive lines on your chart throughout the day. Each line has a name (cryptic by design — fits a 15-character tag), a probability, a direction, and an implied target price. This page is the dictionary.

HUD lines — alphabetical

Direction column: bull = line above current price, price moving up to reach it. bear = line below, price moving down. both = fires in either direction depending on intraday setup. Probabilities are realized OOS touch or close rates (noted where they differ). "Prob" is the headline base probability before the confluence layer applies bonuses/penalties.

Concepts & jargon

Every abbreviation you'll hit reading the model pages or the HUD, in one place. Terms with their own deep-dive link to the full concepts page.

TermDefinition
4H SMC trend Smart Money Concepts structural trend on the 4-hour timeframe. +1 bull / −1 bear / 0 neutral. Used as a confluence gate (e.g. MN HOLD requires 4H trend to agree with the open-side distance).
AMD Accumulation → Manipulation → Distribution. An ICT session-structure idea: price accumulates in a range, sweeps a liquidity level (manipulation), then distributes in the real direction.
Base / confluence probability Base is the model's standalone hit rate. Confluence is what you get after the bonus/penalty layer applies adjustments based on other active lines. The live HUD shows confluence-adjusted.
Close-direction vs touch A touch line predicts price will reach the level at any point. A close-direction line predicts the session close will be past it. Touch rates are typically higher than close rates — a magnet can be 80% touch / 50% close.
CRT (Candle Range Theory) ICT pattern: a candle that sweeps the prior candle's extreme then closes back inside projects a move to the prior candle's opposite extreme. Works on any timeframe; 1H is highest-confidence on NQ.
HUD Heads-Up Display — the live chart overlay that paints all active prediction lines with probability tags. See the HUD concept page.
IPDA Interbank Price Delivery Algorithm (ICT term). Longer-horizon liquidity levels — 20-day, 40-day rolling highs and lows.
Killzone ICT term for a time window where volatility / liquidity events cluster. The main ones: Asia (20:00–00:00), London (02:00–05:00), NY AM (08:30–11:00), NY Silver Bullet (10:00–11:00), NY PM (13:30–16:00).
Kill floor After confluence penalties, any line whose probability drops below 40% gets removed from the HUD. Keeps the display clean on conflicted-thesis days.
Magnet A line that predicts a touch, not a direction. Typically carries zero close-direction edge — if you trade a magnet, the edge is in the touch, not the close.
MN / Midnight Open The 00:00 ET 1-minute bar open. Acts as an overnight-to-RTH pivot reference. See MN HOLD-SIDE.
MN HOLD A trend-day filter: when RTH opens 60–200 pts away from MN and 4H SMC trend agrees with that side, price often never crosses MN during RTH. 57% standalone, 64% when extended by 10:00 (PRIME tier).
OR box / OB Opening Range box — 09:30–10:30 ET on NQ. Its high, low, and midpoint anchor the OB RANGE model family.
ORB Opening Range Breakout (5m / 15m variants). Break & close beyond the first N-minute range triggers a directional trade.
PDH / PDL Prior-Day High / Low. Key reference levels carried into the next session as magnets.
PDD Prior-Day Daily (close). Often paired with PDH / PDL as the third-reference trio.
PO / PO range Prior-Overnight range — high, low, midpoint of the overnight session (typically 18:00 prior day → 09:30 RTH open on NQ).
PRIME tier MN HOLD upgrade. When by 10:00 the market has extended ≥60 pts away from RTH open in the hold-side direction, the setup's probability lifts (57 → 64%) and confluence bonuses get an extra tier.
PWH / PWL Prior-Week High / Low. Weekly-liquidity reference levels.
RTH Regular Trading Hours — 09:30–16:00 ET on NQ / ES. Everything outside is overnight.
SMC Smart Money Concepts — trading framework emphasizing liquidity, order blocks, and institutional-behaviour patterns. The chart overlay uses SMC trend on multiple timeframes as a confluence input.
Straddle vs cross-and-close entry Straddle = enter on any bar that touches the level (`Low ≤ level ≤ High`). Cross-and-close = wait for a bar to close past the level. Straddle gets in earlier and usually beats cross-and-close in backtests.
Silver Bullet ICT term for a one-hour "textbook-setup" killzone. The NY Silver Bullet is 10:00–11:00 ET.
STRATEGY_PASS vs TOWARD_VWAP Two opposite VWAP filter conventions. STRATEGY_PASS: long requires Close > VWAP, short requires Close < VWAP — trade with VWAP. TOWARD_VWAP: the opposite — trade toward VWAP (mean reversion). Our backtests show the right convention is signal-dependent.
TTL Time-to-live — how long a line stays on the HUD after it fires. `240` means 4 hours, `390` means through the RTH close.
VWAP Volume-Weighted Average Price, rolling intraday. Used both as a magnet line and as a filter gate on most strategies.

How to read the HUD

Each HUD line carries four fields on-chart:

When multiple lines agree (same direction, similar price), the confluence layer nudges their probabilities up. When a dominant regime line (MN HOLD, OB MID) is active, lines that oppose it get penalized or killed. The HUD concept page has the visual breakdown.
