H4 C2 detector

This script is a multi‑stage tool for detecting CISD-based reversals, H4 C2 setups, and related liquidity structures on any chart timeframe.
​

Purpose
The indicator combines a CISD swing/reversal engine (Stage 1) with higher‑timeframe H4 Fair Value Gaps (FVGs), Order Blocks (OBs), and swing levels (Stage 2 & 3) to confirm a C2 reversal signal with higher‑timeframe confluence.
​

Stage 1 – CISD swing engine
Stage 1 tracks bullish and bearish swing sequences using pivots and liquidity‑sweep logic.
​

You can choose the detection method: Classic vs Liquidity Sweep, plus swing length and minimum/maximum sequence duration.
​

The script builds and maintains arrays of swing highs/lows and “bins” (bullish/bearish lines) that turn from one color to the other once price breaks them with enough duration, flipping an internal trend state between bullish, bearish, or neutral.
​

Labels (“CISD”) and dashed lines are drawn when a valid CISD swing reversal is confirmed, visually showing where the current trend flipped.
​

Stage 2 – H4 structure (FVG, OB, swings)
Stage 2 pulls H4 data on any chart to add higher‑timeframe context.
​

It requests H4 OHLC, then detects H4 bullish/bearish FVGs and optionally plots their CE (consequent encroachment) levels with boxes and dashed lines.
​

It marks confirmed H4 order blocks (bullish from down candles broken up, bearish from up candles broken down) and tracks whether they remain mitigated or not.
​

It also identifies H4 swing highs and lows, draws dotted lines for active swing levels, and flags when they are mitigated or should be hidden.
​

Stage 3 – C2 confirmation and alerts
Stage 3 ties the CISD trend state with the H4 structure to define and confirm C2 signals.
​

Boolean flags c2_bull and c2_bear turn true when the CISD trend aligns with price interacting correctly with H4 swing lines and, optionally, FVG/OB context.
​

The script plots C2 markers (up/down triangles) on the chart when bullish or bearish C2 conditions are met.
​

It defines alertcondition() for bullish, bearish, and “any” C2 reversals and also triggers a bar‑close alert when any C2 signal confirms, so you can set TradingView alerts for automated notifications.
​

Final table and bias display
To summarize state, the script shows a compact table in the top‑right corner of the chart.
​

Row 1 shows “Daily Bias” derived from the CISD engine (BULLISH, BEARISH, or NEUTRAL) with matching colors.
​

Row 2 shows the H4 C2 status as CONFIRMED or WAITING, helping you quickly see whether a valid higher‑timeframe‑aligned reversal has printed.
