Meridian replaces flat scores and rigid AND-gates with a regime-aware lattice, a live liquidity memory map, and path-integrity tracking — so every signal carries a grade, a regime, and a managed trade from entry to TP3.
Meridian never takes a trade off one signal. Three gates must clear in order — a regime-aware bias, a liquidity arm, and an untapped zone retest — before the engine commits a managed path from entry to TP3.
The engine classifies every bar TREND, RANGE, or TRANSITION. In TREND it trades only with the ribbon and cloud; in RANGE it fades premium and discount extremes; in TRANSITION it demands a denser lattice before anything fires.
A setup only arms on a confirmed liquidity sweep, a volume-backed VWAP reclaim, or a bullish/bearish CHoCH. The arm expires after a preset number of bars — stale setups are dropped automatically.
Price must tap an untapped FVG (or order block) while the event lattice reads at least your minimum grade. No-chase blocks stretched entries in TREND; RANGE gets a fade-into-extremes exception.
On entry, Meridian plots a structural stop and three targets. PATH CONFIRM fires when TP1 is touched; PATH BREAK fires if price closes beyond the stop first. One path per direction, tracked live.
Mutual exclusion built in. If both long and short fire on the same bar, Meridian keeps the higher-density side — or stands aside entirely on a tie. It will not hand you a conflicting pair.
Each pillar replaces a flat rule with a dynamic read — regime context, a decaying memory of liquidity, clustered evidence, and a tracked trade path.
Every bar is classified TREND, RANGE, or TRANSITION from ATR relative strength, a manual ADX(14), and EMA ribbon 9/21/50 alignment. Bias, risk-reward, and no-chase logic all shift with the regime.
Confirmed sweeps push liquidity pools into a rolling memory — each with a price, direction, intensity, and a decaying magnet. Revisit with volume and the magnet strengthens; TP3 can target the opposing pool.
Not a flat score. Sweeps, CHoCH, BOS, VWAP reclaims, band touches, and session tags land in a rolling lattice. Density is measured in time and price — each event type counted once — then graded WATCH to SINGULAR.
Entry at the close, a structural stop beyond the sweep or zone invalidation, and three targets: TP1 at VWAP or the nearest sigma band, TP2 by risk × RR, and TP3 at the opposing magnet or 1.5× TP2.
On every signal Meridian stores the entry, stop, and targets, then follows the trade. TP1 touched first is a PATH CONFIRM; price closing beyond the stop first is a PATH BREAK. Both print labels and fire alerts.
America/New_York windows — Asia, London, the NY killzone, and a configurable Silver Bullet — act as amplifiers, not mandatory AND-gates. A setup in-window gets a lattice density boost, never a forced wait.
The lattice counts how many different kinds of confluence cluster near price — then grades the setup. Session windows amplify, and a high-magnet pool in range can push a setup to the top.
Five or more distinct event types clustered in time and price — with a high-magnet pool in range. The rarest, highest-conviction read. Maximum size and RR.
Four event types in the lattice — sweep, structure, VWAP, and session alignment converging at one level. Full position size.
The standard smart-money stack — a sweep, a structure shift, and a fresh imbalance. Standard position size.
Core confirmation only. Valid for research and tracking — raise the minimum grade to PRIME before taking live size.
Each institutional session tags the lattice for a density boost. Unlike rigid AND-gates, a setup never has to wait for the "right" window — it simply scores higher inside one.
A sweep of the prior London high or low inside the Silver Bullet window, tagged for a lattice boost. A clean reversal read.
A volume-spike test of the prior New York extreme with trend alignment — institutional defense of a session high or low.
The London session's range and liquidity form the reference for the Silver Bullet sweep later in the morning.
A break of the prior Asia range after it closes, with structure alignment — the earliest read on the day's directional intent.
Meridian isn't a reskin — it's a synthesis that keeps what both engines do well and replaces their flat scoring with a regime-aware lattice, a liquidity memory map, and path tracking.

Nothing is left to interpretation. Each bubble, arrow, and path marker has a fixed meaning and a matching alert.
Bar-close only. Entry signals confirm on a closed bar — no mid-candle signal that can vanish before the close. Arm bubbles and stage indicators update live by design, but they are state reads, never trade triggers.
Add the script, let the Auto preset derive your timeframe, and trade the read — regime, then arm, then zone.
Paste Meridian_Engine.pine into the TradingView Pine v6 editor, save, and add it to your chart.
Auto derives Scalp, Intraday, Swing, or Position from your chart timeframe — so stop, RR, and lattice sensitivity match the timeframe you're actually trading.
PRIME filters out weak lattices for live trading. Keep WATCH for research, and let ELITE and SINGULAR surface your highest-conviction reads.
Enter only when the dashboard shows Armed + a matching Lattice grade + an aligned Regime and Bias. Then manage via Path Confirm and Break.
Create alerts from the script's alertconditions — BUY/SELL, sweep arm, ELITE/SINGULAR, Path Break/Confirm, regime change, and bias flip.
Read the regime, follow the liquidity, and let every signal carry a grade and a tracked path — from entry to TP3. Built for TradingView Pine Script v6.
