Smart ABCD Pattern Structure Indicator (Pullback Logic + EA Compatible + Visual Entry Box)

Specification

This indicator detects ABCD structure-based trading setups using a custom pullback and breakout logic, as discussed below. It works for both bullish and bearish scenarios (mirror logic), with user control over direction selection on the chart.

───────────────
🔹 1. Pullback Logic:
- Pullback is confirmed only after at least 2 red candles (in bullish case) have formed.
- The body of one of these red candles must close below the wick of the last bullish green candle (the one that made the last swing high).
- It doesn’t matter if the red candles are continuous or appear after gaps with green candles in between — what matters is that:
  → There are minimum 2 red candles.
  → The 2nd red candle must close below the 1st red candle (not be a baby candle).
- If a red candle immediately after green closes below the wick, still wait for the second red candle to confirm the structure.

───────────────
🔹 2. Point A Logic:
- After the pullback condition is satisfied, the next green candle is *assumed* as Point A.
- This A point can update dynamically if higher green candles form.
- Once 2 valid red candles form after A, no further A reassignment is done.

───────────────
🔹 3. Point B Logic:
- This is the lowest wick formed between Point A and the candle that confirms Point C.
- Only after Point C is confirmed, B becomes fixed.

───────────────
🔹 4. Point C Logic (Breakout Confirmation):
- A bullish breakout is confirmed only when a candle body closes above the wick high of assumed Point A.
- As soon as this close happens, A, B, and C become fixed.
- Wick breakout is NOT sufficient — body close required.

───────────────
🔹 5. Point D Logic (Entry Trigger):
- After Point C is confirmed, the system waits for any candle (body or wick) to touch Point C's price level.
- If this happens, the setup is marked as ✅ triggered and the box turns GREEN.
- If no candle touches C and price keeps going away, setup remains untriggered (YELLOW).

───────────────
🔹 6. Invalidation Logic:
- If, after assuming Point A but before confirming Point C, any candle breaks below the leg of Point A (lowest point of pullback) — the setup is INVALID.
- Invalidation causes that entire box to be marked RED (if enabled) or removed (based on settings).
- After invalidation, a new structure search begins from the next candle.

───────────────
🔹 7. Visual Display:
- Each valid setup will be drawn as a shaded box on the chart:
  → Yellow box: Pattern formed but Point D not yet triggered.
  → Green box: Point D triggered (entry valid).
  → Red box: Setup invalidated.
- Each Point (A, B, C, D) will be labeled optionally.
- A separate smaller box will mark the Pullback zone (2+ red candles).
- All box styles, label visibility, and colors should be user-editable.
- Boxes should have a thin outline that covers the candles included in the setup.

───────────────
🔹 8. Settings & Inputs:
- Enable Bullish or Bearish pattern (drop-down or checkbox)
- Max candles to scan in history (date-based or candle-based)
- Show triggered boxes: Yes/No
- Show untriggered boxes: Yes/No
- Show invalidated (red) boxes: Yes/No
- Show pullback boxes: Yes/No
- Label Points A/B/C/D: Yes/No
- Color and Style customization for all elements

───────────────
🔹 9. Box Numbering and EA Integration:
- Each box should have an auto-generated unique number shown on chart.
- Only the currently active (most recent valid) box will remain active for EA.
- When a new valid box forms, the previous active one is deactivated.
- This allows EA to target the current live setup only.
- The indicator should be designed with EA-compatibility in mind.
- Entry can be semi-automated (manual click on the box), or fully automated when D is touched — developer will decide based on EA requirements.

───────────────
🔹 10. Additional Optional Features:
- Box expiry feature: option to auto-expire a box if D is not triggered within X candles.
- Stats Panel (optional): show total boxes, triggered, invalidated, etc. on chart.

───────────────
🔹 11. Bearish Setup (Mirror Logic):
- All above logic applies in reverse for bearish patterns.
- Pullback = 2 green candles; breakout = red close below wick of assumed bearish Point A.
- User can select from settings whether to activate bullish or bearish side.

This description covers almost all visual logic, confirmation structure, invalidation rules, and inputs necessary to build a complete indicator for both real-time trading and historical backtesting. Please follow each logic point exactly as outlined.
