Техническое задание
Hello Developers 👋
I already have a fully working EA skeleton (MT4) that:
Deletes all pending orders closer than a configurable distance (in points) to the market price.
Uses WebRequest() to load the ForexFactory JSON calendar every 2 hours.
Filters USD news by impact (High / Medium / Low) and pauses trading 1 min before to 120 min after each event.
Displays the next 5 USD news events directly on the chart, including broker time, UTC time, and a time-difference (Δ) countdown.
Supports Broker ↔ UTC offset and a manual nudge (± minutes) for fine-tuning.
Now I’m looking for a skilled MQL4 developer to finalize, clean up, and stabilize this EA for production use.
---
✅ What’s already done (I provide):
Full working .mq4 source (clean, structured, well commented).
All logic: order-deletion, timer, parsing, panel drawing, and pause logic already implemented.
ForexFactory JSON URL + WebRequest access confirmed working.
---
🔧 Tasks for the freelancer:
1. Code cleanup & optimization
Organize structure, ensure stable execution (no freezes during WebRequest).
Add error handling / fallback if JSON temporarily unavailable.
2. JSON Parsing improvement
Optionally replace string-search parser with a small JSON lib (e.g. JAson.mqh).
Make sure future field-name changes (impact, country, timestamp) won’t break parsing.
3. On-Chart Panel refinement
Add optional color-highlight when a news event is within the pause window.
Optionally add a countdown display ("Next High Impact: in 12 min").
Keep lightweight and compatible with low-latency VPS environments.
4. Broker ↔ UTC synchronization
Verify offset logic and manual nudge (± minutes) accuracy.
Ensure displayed times and pause logic are 100 % in sync.
5. Final test & delivery
EA must compile with no warnings.
Run stable on standard brokers (IC Markets, Vantage, RoboForex etc.).
Documentation of parameters (short readme).
📎 Deliverables:
Final .mq4 source + compiled .ex4
Short change log (what was improved)
Optional small video/screenshot showing panel & pause logic working
Demo test for 5 days
