ICT PDA - Gold & BTC (QuickScalp Bias/FVG/OB/OTE + Alerts)

What this script does
This indicator implements a complete ICT Price Delivery Algorithm (PDA) workflow tailored for XAUUSD and BTCUSD. It combines HTF bias, OTE zones, Fair Value Gaps, Order Blocks, micro-BOS confirmation, and liquidity references into a single, cohesive tool with early and final alerts. The script is not a mashup for cosmetic plotting; each component feeds the next decision step.

Why this is original/useful

Symbol-aware impulse filter: A dynamic displacement threshold kTune adapts to Gold/BTC volatility (body/ATR vs. per-symbol factor), reducing noise on fast markets without hiding signals.

Scalping preset: “Quick Clean” mode limits drawings to the most recent bars and keeps only the latest FVG/OB zones for a clear chart.

Three display modes: Full, Clean, and Signals-Only to match analysis vs. execution.

Actionable alerts: Early heads-up when price enters OTE in the HTF bias direction, and Final alerts once mitigation + micro-break confirm the setup.

How it works (high-level logic)

HTF Bias: Uses request.security() on a user-selected timeframe (e.g., 240m) and EMA filter. Bias = close above/below HTF EMA.

Dealing Range & OTE: Recent swing high/low (pivot length configurable) define the range; OTE (62–79%) boxes are drawn contextually for up/down ranges.

Displacement: A candle’s body/ATR must exceed kTune and break short-term structure (displacement up/down).

FVG: 3-bar imbalance (bull: low > high[2]; bear: high < low[2]). Latest gaps are tracked and extended.

Order Blocks: Last opposite candle prior to a qualifying displacement that breaks recent highs/lows; zones are drawn and extended.

Entry & Alerts:

Long: Bullish bias + price inside buy-OTE + mitigation of a bullish FVG or OB + micro BOS up → “PDA Long (Final)”.

Short: Bearish bias + price inside sell-OTE + mitigation of a bearish FVG or OB + micro BOS down → “PDA Short (Final)”.

Early Alerts: Trigger as soon as price enters OTE in the direction of the active bias.

Inputs & controls (key ones)

Bias (HTF): timeframe minutes, EMA length.

Structure: ATR length, Impulse Threshold (Body/ATR), swing pivot length, OB look-back.

OTE/FVG/OB/LP toggles: show/hide components.

Auto-Tune: per-symbol factors for Gold/BTC + manual tweak.

Display/Performance: View Mode, keep-N latest FVG/OB, limit drawings to last N bars.

Recommended usage (scalping)

Timeframes: Execute on M1–M5 with HTF bias from 120–240m.

Defaults (starting point): ATR=14, Impulse Threshold≈1.6; Gold factor≈1.05, BTC factor≈0.90; Keep FVG/OB=2; last 200–300 bars; View Mode=Clean.

Workflow: Wait for OTE in bias direction → see mitigation (FVG/OB) → confirm with micro BOS → manage risk to nearest liquidity (prev-day H/L or recent swing).

ملخص عربي:
المؤشر يطبق تسلسل PDA عملي للذهب والبتكوين: تحيز من فريم أعلى، مناطق OTE، فجوات FVG، بلوكات أوامر OB، وتأكيد micro-BOS، مع تنبيهات مبكرة ونهائية. تمت إضافة وضع “Quick Clean” لتقليل العناصر على الشارت وحساسية إزاحة تتكيّف مع الأصل. للاستخدام كسكالب: نفّذ على M1–M5 مع تحيز 120–240 دقيقة، وابدأ من الإعدادات المقترحة بالأعلى. هذا إطار سلوكي وليس توصية مالية.
