SMC Suite — Order Blocks • Breaker • Liquidity Sweep • FVG What it does: Maps institutional SMC structure (OB → Breaker flips, Liquidity Sweeps, and 3-bar FVGs) and alerts when price retests those zones with optional rejection-wick confirmation. Why this isn’t “just a mashup”? This tool implements a specific interaction between four classic SMC concepts instead of only plotting them side-by-side: 1. OB → Breaker Flip (automated): When price invalidates an Order Block (OB), the script converts that zone into a Breaker of opposite bias (bullish ⇄ bearish), extends it, and uses it for retest signals. 2. Liquidity-Gated FVGs: Fair Value Gaps (3-bar imbalances) are optionally gated—they’re only drawn/used if a recent liquidity sweep occurred within a user-defined lookback. 3. Retest Engine with Rejection Filter: Entries are not whenever a zone prints. Signals fire only if price retests the zone, and (optionally) the candle shows a rejection wick ≥ X% of its range. 4. Signal Cooldown: Prevents spam by enforcing a minimum bar gap between consecutive signals. These behaviors work together to catch the sequence many traders look for: sweep → impulse → OB/FVG → retest + rejection. Concepts & exact rules 1) Impulsive move and swing structure • A bar is “impulsive” when its range ≥ ATR × Impulsive Mult and it closes in the direction of the move. • Swings use Pivot Length (lenSwing) on both sides (HH/LL detection). These HH/LLs are also used for sweep checks. 2) Order Blocks (OB) • Bullish OB: last bearish candle body before an impulsive up-move that breaks the prior swing high. Zone = min(open, close) to low of that candle. • Bearish OB: last bullish candle body before an impulsive down-move that breaks the prior swing low. Zone = high to max(open, close). • Zones extend right for OB Forward Extend bars. 3) Breaker Blocks (automatic flip) If price invalidates an OB (closes below a bullish OB’s low or above a bearish OB’s high), that OB flips into a Breaker of opposite bias: • Invalidated bullish OB → Bearish Breaker (resistance). • Invalidated bearish OB → Bullish Breaker (support). Breakers get their own style/opacity and are used for separate Breaker Retest signals. 4) Liquidity Sweeps (decluttered) • Bullish sweep: price takes prior high but closes back below it. • Bearish sweep: price takes prior low but closes back above it. Display can be tiny arrows (default), short non-extending lines, or hidden. Old marks auto-expire to keep the chart clean. 5) Fair Value Gaps (FVG, 3-bar) • Bearish FVG: high[1] < low[2] and current high < low[2]. • Bullish FVG: low[1] > high[2] and current low > high[2]. • Optional gating: only create/use FVGs if a sweep occurred within ‘Recent sweep’ lookback. 6) Retest signals (what actually alerts) A signal is true when price re-enters a zone and (optionally) the candle shows a rejection wick: • OB Retest LONG/SHORT — same-direction retest of OB. • Breaker LONG/SHORT — opposite-direction retest of flipped breaker. • FVG LONG/SHORT — touch/fill of FVG with rejection. You can require a wick ratio (e.g., bottom wick ≥ 60% of range for longs; top wick for shorts). A cooldown prevents back-to-back alerts. How to use 1. Pick timeframe/market: Works on any symbol/TF. Many use 15m–4h intraday and 1D swing. 2. *Tune Pivot Length & Impulsive Mult: • Smaller = more zones and quicker flips; larger = fewer but stronger. 3. Decide whether to gate FVGs with sweeps: Turn on “Require prior Liquidity Sweep” to focus on post-liquidity setups. 4. Set wick filter: Start with 0.6 (60%) for cleaner signals; lower it if too strict. 5. Style: Use the Style / Zones & Style / Breakers groups to set colors & opacity for OB, Breakers, FVGs. 6. Alerts: Add alerts on any of: • OB Retest LONG/SHORT • Breaker LONG/SHORT • FVG LONG/SHORT Choose “Once per bar close” to avoid intrabar noise. Inputs (key) • Swing Pivot Length — swing sensitivity for HH/LL and sweeps. • Impulsive Move (ATR ×) — defines the impulse that validates OBs. • OB/FVG Forward Extend — how long zones project. • Require prior Liquidity Sweep — gate FVG creation/usage. • Rejection Wick ≥ % — confirmation filter for retests. • Signal Cooldown (bars) — throttles repeated alerts. • Display options for sweep marks — arrows vs short lines vs hidden. • Full color/opacity controls — independent palettes for OB, Breakers, and FVGs (fills & borders). What’s original here • Automatic OB → Breaker conversion with separate retest logic. • Liquidity-conditioned FVGs (FVGs can be required to follow a recent sweep). • Unified retest engine with wick-ratio confirmation + cooldown. • Decluttered liquidity visualization (caps, expiry, and non-extending lines). • Complete styling controls for zone types (fills & borders), plus matching signal label colors.
