Ultimate MT5 Trend-Aligned Pattern Indicator (Engulfing/Hammer) with Dual EMA & HTF Fil

CRITICAL ARCHITECTURE REQUIREMENT:
The indicator must run SILENTLY in the background. It must ONLY send Mobile Push Notifications and Laptop Pop-Up Alerts. Absolutely NO lines, arrows, shapes, or panels should be drawn on the chart to ensure maximum execution speed and zero chart clutter.

Core Requirements:

1. Time/Session Monitoring (Customizable UAE Time):
   - The indicator must actively look for setups during user-defined hours entered in UAE Local Time (GMT+4) (e.g., 16:30 to 22:00).
   - The code must automatically handle the conversion from UAE Time to the specific Broker's Chart Clock, including automatic adjustments for US/Broker Daylight Saving Time (DST).

2. Multi-Timeframe Selection & Candlestick Pattern Recognition:
   - User dropdown menu to select the scanned timeframe (M5, M15, or M30).
   - The indicator must detect the completion of the following 3 patterns strictly on the selected timeframe's candle close:
     * Engulfing (Bullish Engulfing for BUY / Bearish Engulfing for SELL)
     * Hammer (Bullish Rejection candle for BUY)
     * Shooting Star (Bearish Rejection candle for SELL)

3. Dual EMA Zone Filter (Execution Timeframe):
   - Add two customizable EMAs calculated on the selected timeframe: Fast EMA (Default: 9) and Slow EMA (Default: 20).
   - The candlestick pattern must form/close inside or touching the gap between the 9 EMA and 20 EMA (the Value Zone).

4. Higher Timeframe (HTF) Trend Filter (CRITICAL FOR 75%+ WINRATE):
   - To prevent trading against the major market trend, the indicator must automatically check a Higher Timeframe trend using a customizable Trend EMA (Default: 50 EMA).
   - HTF Mapping Rule: 
     * If the scanned timeframe is M5 or M15, the HTF Trend Filter is automatically calculated on the H1 (1-Hour) chart.
     * If the scanned timeframe is M30, the HTF Trend Filter is automatically calculated on the H4 (4-Hour) chart.
   - BUY Alert Validation: Only trigger a BUY alert if the execution EMAs are in a bullish structure (9 > 20) AND the current close price on the HTF chart is strictly ABOVE the HTF Trend EMA.
   - SELL Alert Validation: Only trigger a SELL alert if the execution EMAs are in a bearish structure (9 < 20) AND the current close price on the HTF chart is strictly BELOW the HTF Trend EMA.

5. Non-Repaint & Zero Delay Alert Logic:
   - The Mobile Push Notification and Laptop Pop-Up must trigger within 1 to 2 SECONDS exactly at the millisecond the scanned candle closes and all filters align.
   - The alert text must explicitly state the Symbol, Scanned Timeframe, Direction, and Pattern Name (e.g., "XAUUSD M15: BUY - Hammer (HTF Trend Aligned)").
   - Signals must be strictly non-repaint.
