Which indicator is best for beginners?
For a beginner trader, Moving Average (EMA 50 or EMA 200) combined with RSI 14 is the most accessible starting point. The EMA shows you the dominant trend direction, while RSI helps you identify overbought/oversold conditions. As you gain experience, add MACD for momentum and ATR for stop-loss calculation. Avoid placing more than 3-4 indicators on the chart during the first 6 months.
How do I choose indicators for gold (XAU/USD)?
Gold is a high-volatility instrument with strong moves. The most effective tested combination is: EMA 20 + EMA 50 on H4 (trend), MACD divergence (reversal timing), ATR for stop-loss (risk management proportional to volatility). For scalping on M5, add VWAP for institutional entry. Avoid purely oscillator-based setups (single RSI) — gold can stay overbought for weeks in a strong trend.
Are indicators enough to make consistent profit?
No. Indicators are tools, not systems. A profitable trader combines indicators + price action + risk management (the 1-2% rule per trade) + psychological discipline. Indicators give probabilities, not certainties. A system with a 50% win rate and 1:2 risk/reward is profitable; a system with a 70% win rate and 1:0.5 risk/reward is a loser.
Which indicators work best for scalping?
For scalping M1-M5: EMA 9 and EMA 21 (fast cross-over), VWAP (institutional price reference), Stochastic 5,3,3 (fast momentum), ATR on M5 (stop calculation). The EMA 50/100 crossover strategy on M1 GBP/USD is documented by Admiral Markets as a popular scalping strategy. Avoid slow indicators (standard MACD, ADX) on M1 — they generate signals too late.
How do I install a custom indicator in MetaTrader 4?
Steps: (1) Download the `.ex4` or `.mq4` file. (2) In MT4 → File → Open Data Folder. (3) Go to MQL4 → Indicators → paste the file there. (4) Restart MT4 or right-click "Indicators" in the Navigator → Refresh. (5) The indicator appears under Navigator → Custom Indicators — drag it onto the chart. For MT5, the folder is MQL5 → Indicators and the extensions are `.ex5`/`.mq5`.
What is the difference between MT4 and MT5 in terms of indicators?
MT4 has approximately 30 built-in indicators and uses the MQL4 language. MT5 has more than 38 built-in indicators, supports more non-standard timeframes (M2, M3, M10), and uses MQL5, which allows multi-currency back-testing. Many popular indicators (LuxAlgo SMC, UT Bot) have versions for both platforms. MT5 is better suited for complex indicators and professional back-testing; MT4 remains preferred for legacy EAs and simplicity.
Do indicators repaint? How do I recognize a repainting indicator?
Yes, many custom indicators repaint — they change historical signals when new price data arrives. This makes them unusable for live trading, even if they look perfect on historical charts. How to recognize one: (1) download it, apply it on a demo, observe whether arrows/zones shift after a candle closes; (2) use the Strategy Tester in visual mode; (3) check reviews on MQL5 Market. Standard MT4/MT5 indicators (RSI, MACD, MA) do not repaint. Indicators based on ZigZag, Fractals, or projected pivots repaint by design — they can be used, but with a clear understanding of this.
