Indicators with a job — not with faith
Original guides: what each tool measures, how to read it, common mistakes and what to combine. Then practice in the interactive lab.
Averages
Trend
Smooth price to show the dominant direction. SMA weights all periods equally; EMA weights recent prices more.
RSI
Momentum
0–100 oscillator comparing recent gains to losses. Measures momentum, not an “absolute top”.
MACD
Momentum
Difference between two EMAs, with a signal line and histogram. Shows momentum and impulse shifts.
Bollinger
Volatility
Volatility envelope around a moving average. Touches are not automatic reversals.
Stoch
Momentum
Oscillator of where the close sits in a recent range. Extremes fail often in strong trends.
ATR
Volatility
Measures typical range. Useful for stops, targets and “is the market wide or quiet?”.
VWAP
Volume / flow
Volume-weighted average price. More native to equities/futures; use carefully in retail FX.
ADX
Trend
Measures trend strength (not direction by itself). High ≈ trend present; low ≈ range more likely — with failures.
OBV
Volume / flow
On-Balance Volume idea. In retail FX, volume is a fragile proxy — skepticism required.
Fib
Trend
Ratio grid between swings. Easy to curve-fit; needs clear swings and risk.
SAR
Trend
Trailing dots that flip sides. Useful as conceptual trailing study; whipsaws in ranges.
Combo
Trend
At most trend + momentum + volatility. Three roles, not ten identical lines.
