MACD, RSI & moving averages,
in plain English.

Adding indicators on OKX

1. Open the candlestick chart (landscape or desktop is easier).
2. Tap “Indicators”.
3. Main-chart overlays: MA, EMA, BOLL.
4. Sub-chart panels: VOL, MACD, RSI, KDJ.
5. Keep default parameters to start.

One overlay and two panels is plenty. Test everything in demo mode first.

Moving averages: the trend

• Price above a rising MA: uptrend bias; the reverse is a downtrend bias.
• Short MA crossing above long MA: “golden cross”; below is a “death cross”.
• EMA vs MA: EMA weights recent prices more — faster, but more false signals.

Moving averages always lag.

MACD: momentum and turns

• Bullish crossover: MACD line crosses above the signal line.
• Bearish crossover: crosses below.
• Zero line: crossovers above zero carry more weight.
• Histogram: growing bars = strengthening momentum.

RSI: overbought and oversold

• Above 70: overbought — may pull back.
• Below 30: oversold — may bounce.
• Divergence: price makes a new high but RSI doesn’t — momentum fading.

The trap: in strong trends RSI can stay above 70 for weeks. Shorting every “overbought” reading gets you squeezed.

Bollinger Bands and KDJ

• Squeeze: narrowing bands often precede a big move.
• Expansion: a move is underway; watch which band price breaks.
• Riding the upper band is strength, not an automatic sell.

KDJ is a faster, noisier cousin of RSI — know it, don’t rely on it.

Why indicators fail — three rules

1. They’re calculated from past prices; they describe, they don’t predict.
2. Confirm with more than one: trend + momentum + volume.
3. Signals don’t size positions — stops do. See risk management.
