Request for Adding a News Filter Feature to Existing Forex EA

I am interested in enhancing my current Forex Expert Advisor (EA) by integrating a news filter functionality. The primary objective of this feature is to prevent the EA from executing trades shortly before high-impact news events. Below, I have detailed the specifications for this feature:

1. Feature Overview:

• The EA should automatically fetch upcoming news events from a reliable financial news source or economic calendar (e.g., Forex Factory, Investing.com, or any other preferred provider you suggest).
• The news filter should specifically look for high-impact news events related to the currencies my EA trades with.
• Trading should be temporarily disabled starting from a predefined period before the scheduled news event (e.g., 1 hour) and resume after a predefined period post the news event (adjustable parameters).

2. Functional Requirements:

• Automatic News Fetching: The system should automatically retrieve the upcoming high-impact news events, including the event time, affected currency, and impact level.
• Time Parameters: The EA should have adjustable input parameters in the settings that allow me to define:
  • How long before a news event the EA should stop trading (e.g., "StopTradeBeforeNews" in minutes/hours).
  • How long after a news event the EA should resume trading (e.g., "ResumeTradeAfterNews" in minutes/hours).
• Filter by Currency Pair: The news filter should analyze the currency pairs in the market watch or those that the EA is intended to trade and correlate with the news events related to these currencies.
• Visual Indicator: (Optional) A visual display on the chart indicating the 'no-trade' periods before and after high-impact news events.

3. Technical Considerations:

• Please ensure the solution is efficient and doesn't excessively consume resources, as it will be running continuously while the Forex market is open.
• The implementation should handle any data fetching errors gracefully and not cause the EA to crash or behave unexpectedly. It should also log errors for troubleshooting.
• Ensure the news source's API or data feed is reliable, has good uptime, and the terms of use allow for our intended usage.

4. Testing and Validation:

• Please provide a method for testing the new feature in a demo trading environment to validate functionality before any live trading occurs.
• I'd appreciate a brief walkthrough of how the feature was implemented and how to adjust the settings.

5. Delivery:

• Kindly provide an estimated timeline for when you expect the modification to be completed.
• Please include detailed documentation on the new feature's functionality and any changes made to the EA.

I am open to any suggestions you may have for improving the functionality or efficiency of this feature. Please provide a quote for this service and an estimated time of completion. If you need any further information or clarification to provide an accurate quote, feel free to ask.

Thank you for your assistance.
