Overview
Alpha News Shield is an MT4 indicator designed to help you plan and reduce trading activity around scheduled economic events.
It displays upcoming events on the chart (panel, countdown, and optional vertical lines) and can control terminal-wide protection using global variables.
When the protection window is active, the indicator can set a “trading allowed” flag that other Expert Advisors can read before sending new orders.
Optional auto-close rules can close positions before selected events (if enabled).
The indicator requires an internet connection and WebRequest permission to download the calendar feed.
What the Indicator Does
The indicator downloads economic calendar data via WebRequest and parses upcoming events.
It shows a compact list of upcoming events and a countdown to the next event.
It can draw vertical event lines on the chart at the scheduled time.
When protection is enabled, it sets terminal global variables to indicate whether new trading should be blocked during a configurable time window.
Optional auto-close rules can close positions before events based on your settings (for example, close all or only profitable positions).

Risk Management & Safety Notes
This indicator does not open trades by itself. Trading decisions and execution remain your responsibility.
Trading involves risk, and losses are possible—especially during fast news moves where spreads and slippage can increase.
Auto-close and trading-block logic depends on terminal connectivity, broker execution, and correct time settings.
Calendar availability depends on the data source and your terminal’s ability to connect via WebRequest.
For terminal-wide blocking to work, your EAs must be designed to read the provided global variables before opening trades.
Always test your settings on a demo account first.

If you want your EAs to respect the block, ensure they read the trading-allowed global variable before sending new orders.
Recommended Evaluation
Verify that the panel updates and events appear on a live or demo chart (internet/WebRequest required).
Check that the countdown matches your broker time and that event lines align with the expected time on the chart.
Enable protection with a wide window at first to confirm the “blocked/allowed” status changes as expected.
If using auto-close, test on a demo account to confirm which positions are closed and when.
Validate EA integration by confirming your EA skips new entries while trading is blocked.
Review logs in the Experts/Journal tabs to confirm feed updates and any access errors.
Compatibility
Platform: MetaTrader 4 (MT4).
Requires WebRequest and an active internet connection to download calendar data.
Works on live and demo charts; it is not intended for Strategy Tester because online data is required.
Terminal-wide protection requires EAs that check the global variable flag before opening trades.
