Trix 4 (MT5) — review, price and free alternatives

The indicator, internally named FEMA.mq5, calculates four sequential EMAs on closing prices to produce a final smoothed output; this layered smoothing reduces whipsaw and provides clearer direction than a single EMA.

What makes Trix 4 unique is its staged exponential smoothing approach and the decision to display results in a dedicated indicator window, which simplifies signal reading and reduces chart clutter. The algorithm calculates EMA1 from price, then applies subsequent EMAs to the prior EMA output through four stages to produce a final value and optional histogram or signal line. Trix 4 performs best in trending markets and on higher timeframes such as H1 and H4 where the smoothing preserves directional moves. Omar Mohamad El Marstani designed the indicator with configurable parameters and conservative defaults; integration with position sizing rules and external risk logic is recommended. Overall, Trix 4 provides an objective technical building block for MT5 systems that need stable trend signals without excessive curve-fitting.

Trix 4 aligns with a moderate risk profile when used with conservative position sizing. The indicator itself does not enforce stops, so traders should apply fixed or volatility-based stop loss strategies externally to limit downside. Recommended position sizing is risk-per-trade based, for example 0.5–1.5% of equity per trade depending on account tolerance. Vulnerabilities include sideways or low-volatility markets where the smoothing can delay signals and increase latency into turning points. For live use, a recommended account size is at least $500 for micro positions, ideally $1,000–$5,000 for meaningful position sizing and realistic drawdown absorption. Integrating Trix 4 into a portfolio with other non-correlated instruments reduces concentration risk.

Install Trix 4 into MT5 by copying the TRIX_4.mq5 file into the Indicators folder in the MQL5 directory and restarting the platform. Attach the indicator to an H1 or H4 chart and review default smoothing periods; adjust stage lengths and signal sensitivity to match your target timeframe. Recommended broker types are ECN or STP brokers with low spreads for forex pairs and reliable execution for higher timeframe testing. Use a demo account for at least 3 months of forward testing and run a 12-month historical backtest on the chosen pair. Monitor live trades with small size before increasing allocation.
