I need high profitable ea bot I don't have any strategy so i need ready ea to test

I am looking for MQL5 developers to pitch solutions or build an Expert Advisor (EA) for XAUUSD (Gold) designed to capture high-volatility price movements during major high-impact news events (NFP, CPI, FOMC).

Key Requirements:

1. News Filter: Must use MQL5's built-in economic calendar ( CalendarValueHistory ) to automatically detect and trigger during high-impact USD news, remaining inactive during normal hours.

2. Execution Model: Fast Stop-and-Reverse (SAR) or bracket execution logic with dynamic trailing stops.

3. Testing Phase: I want to evaluate performance and behavior in the Strategy Tester / Demo environment before proceeding.

Please let me know if you have a ready-made solution for testing or if you can develop/customize this strategy, along with your estimated cost and timeline.
