MT4 Multi-Timeframe Forex Signal EA

OSYSTIC engineered an alert-only MetaTrader 4 Expert Advisor to translate multi-timeframe swing-trading rules into deterministic, closed-candle signals. The engagement delivered a robust validation baseline separating signal generation from trade execution.

01 / CONTEXT

The challenge

Translating discretionary multi-timeframe indicator rules into deterministic logic while handling asynchronous pair confirmation within a fixed 12-hour window. The system needed to preserve H4 regime constraints while waiting for M30 confirmation events, suppress duplicate notifications, and maintain an alert-only safety boundary.

What OSYSTIC built

OSYSTIC delivered a specialized alert-only MetaTrader 4 Expert Advisor combining an H4 regime with M30 closed-candle confirmation, pair-group state machines, and a strict 12-hour confirmation gate. The system delivered notifications via MetaTrader mobile push and email without placing or managing trades.

Engineering Highlights

  • Translated multi-timeframe MACD and OsMA rules into deterministic state-machine logic.
  • Engineered asynchronous cross-symbol confirmation with a 12-hour maximum window.
  • Implemented duplicate suppression and new-sequence re-alert handling.
  • Established an alert-only safety boundary separating signal generation from order execution.
  • Created a controlled test-only evidence harness for rare signal validation.

Capabilities

  • Multi-Timeframe Analysis
  • Rule-Based Automation
  • State Machine Design
  • Signal Validation & Notification
  • Asynchronous Cross-Symbol Confirmation
