EURUSD news process notes stay pair-specific so I do not copy-paste gold habits onto a major.

ECB, US Tier-1, and a small set of European prints get written rules: blackout length, size after reopen, and whether I allow continuation or only stand aside. The notes live next to the platform, not in a folder I never open.

Pair-specific lines I keep
1. Which events force flat even if I am "only in a tiny scalp."
2. Which events allow reduced size after the timer if spread is clean.
3. Which events are watch-only because my edge never cleared cost historically.

Generic "be careful around news" advice never changed my behaviour. Written EURUSD lines did.

If you keep pair notes, what is the one EURUSD rule you wish you had written down a year earlier?

When EURUSD notes conflict with a generic news checklist, the pair notes win. Checklists are for coverage; notes are for behaviour. I would rather maintain one sharp EURUSD page than a binder that never gets opened during the open.

Hi LondonScalper,

The one EURUSD rule I wish I had written down a year earlier is: The initial ECB/NFP spike is almost always a liquidity sweep, and the real structural move does not begin until 15 minutes into the press conference.

Trying to fade or join the very first 1-minute or 5-minute candle on a major EURUSD news release is gambling against spread expansion. Waiting for the first 15-minute candle to close dictates the true intent: if it closes back inside the pre-news range, the initial spike was a trap. If it closes near its extreme, the market has repriced and continuation is viable.

Your philosophy of keeping pair-specific rules pinned to the environment where execution happens is the most effective way to combat heat-of-the-moment rationalization. Gold rules will ruin a EURUSD account, and vice versa.

To keep your notes living directly next to the platform, here is an MQL5 script. When executed on a chart, it renders your pair-specific news rules as a persistent on-chart dashboard. It intentionally aborts if dragged onto anything other than EURUSD to enforce your strict pair-isolation rule.

You can bind this script to a hotkey in MT5 or leave it running as an indicator template. The hard stop on the _Symbol check ensures that if you accidentally drag this onto XAUUSD or a GBP pair, it refuses to execute, keeping your pair-specific constraints physically enforced by the platform.

To make this professional-grade, we need to treat it like enterprise software. A script that just dumps raw text onto a chart is fragile.

This upgraded version implements an Object-Oriented (OOP) architecture, uses structs and enums for strict data typing, and renders a dynamic, semi-transparent background panel so your notes are always perfectly legible regardless of your chart template. It also cleanly encapsulates state and handles its own garbage collection.

Architectural Upgrades

Object-Oriented Design: The CNewsDashboard class fully encapsulates UI coordinates, object prefixes, and rendering logic. The main execution block (OnStart) just focuses on data injection.

Strong Typing: Rule categories are now strictly typed using the ENUM_RISK_PROFILE enum, which automatically routes to standard hex colors (Tomato for flat, Gold for reduced, DodgerBlue for execution).

Background Panel: Raw text on a chart gets unreadable when candlesticks cross behind it. This builds an OBJ_RECTANGLE_LABEL behind the text, dynamically calculating height based on array size, creating a clean GUI panel.

Prefix Garbage Collection: All objects are prefixed (EURNews_). The Clear() method only deletes objects matching this string, ensuring it never accidentally wipes out your trendlines or Fibonacci levels.

Posted: **Wed Sep 23, 2026 7:24 pm**

To elevate this to an enterprise-grade execution tool, it must be converted from a static Script into an Event-Driven Indicator.

A Script executes once and dies, leaving "orphaned" objects on the chart. A professional tool manages its own lifecycle. This architecture introduces state management (a collapsible UI to save chart real estate), event listeners (mouse clicks), and bulletproof garbage collection (OnDeinit) so the chart remains pristine when the tool is removed.

It also upgrades the EURUSD isolation rule: instead of just halting execution, it returns INIT_FAILED, which forces the MetaTrader terminal to automatically detach the indicator from invalid charts.

Institutional Upgrades Implemented:

Indicator Lifecycle (OnInit, OnDeinit): Instead of a run-once script, this runs continuously in the background. If you remove the indicator or change templates, OnDeinit fires, executing the class destructor and immediately purging every associated UI object.

INIT_FAILED Hard Stop: If dragged onto Gold, it doesn't just display a warning—it actively returns an initialization failure to the MetaTrader engine, forcing the platform to instantly detach the tool.

Stateful UI (Collapse/Expand): By mapping CHARTEVENT_OBJECT_CLICK to the Toggle label, you can collapse the panel into a tiny title bar while trading, and click [+] EXPAND when a news event approaches.

Z-Order Stacking: Added OBJPROP_ZORDER properties. Text is explicitly assigned 1 and the background panel 0. This guarantees the background panel will never accidentally swallow the text, regardless of how MT5 renders its layers on your specific workstation hardware.
