OHLC-OLHC [ARKN] ARKN combines three time-based analysis tools into a single overlay so that session context, higher-timeframe structure, and cross-asset divergence can be read together on one chart, without stacking three separate indicators.
What it does
Killzones — Draws up to four configurable session boxes (defaults: Asia, London, NY AM, NY PM) with optional session high/low pivot lines, midpoints, day-of-week labels, opening-price lines, and an "opening candle" marker. Pivots can extend until mitigated or past mitigation, with optional alerts when a session high or low is broken.
HTF Candles — Renders up to four higher-timeframe candle sets to the right of the live price, each with its own timeframe and display count. Optional Fair Value Gap and Volume Imbalance boxes, a remaining-time countdown, and interval labels are drawn directly on the projected candles.
Sequential SMT (SSMT) — Detects SMT-style divergence between correlated instruments across nested cycles (Micro, 90-minute, Daily, Weekly, Monthly). Triads can be set automatically for common groups (metals, indices, FX, crypto, futures) or defined manually, with an inverse option for negatively-correlated pairs. Both standard (wick-based) and hidden (body/close-based) divergences are supported.
Why these three together
The three modules answer three sequential questions a session-based trader asks in order: when (Killzones frame the active session), what structure (HTF Candles show the higher-timeframe bias forming in real time), and confirmation (SSMT flags when a correlated instrument fails to confirm the move). Combining them removes the need to switch layouts or sync timeframes manually, since all three share the same timezone and session logic.
How to use
Set your timezone under Settings; all sessions and cycles reference it.
Each module has a master ON/OFF toggle at the top of its settings group.
For SSMT, either leave Triad Selection on Auto (it picks correlated assets for the current symbol) or set Manual to define your own triad. Lower timeframes show Micro/90m cycles; higher timeframes show Daily/Weekly/Monthly.
HTF Candle timeframes must be higher than the chart timeframe to display.
Settings overview
Global: drawing limit, timeframe limit, timezone, label size, text color, cutoff time. Per module: session times and colors (Killzones), timeframe and candle count (HTF Candles), cycle visibility, line styles, and correlation triads (SSMT).
Note on originality
This script combines well-established, publicly-discussed ICT community concepts — session Killzones, projected higher-timeframe candles, and SMT/Sequential SMT divergence. These concepts are not original to this script; the contribution here is integrating all three into one configurable overlay with shared session and timezone handling. The script is published open-source so the implementation can be reviewed and reused.
