“OSYSTIC translated the multi-timeframe forex strategy requirements into a clean and dependable MT4 signal system. The team was responsive, technically capable, and careful about ensuring the logic behaved consistently across the required timeframes.”
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.
“OSYSTIC translated the multi-timeframe forex strategy requirements into a clean and dependable MT4 signal system. The team was responsive, technically capable, and careful about ensuring the logic behaved consistently across the required timeframes.”
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.
