Moving averages, RSI and MACD are the three indicators you'll meet first — and misuse first. Here's what each one actually measures, how to read it without fooling yourself, and the honest limits every one of them shares.

It repackages numbers you already have — closes, highs, lows — into a smoother or more comparable form. That framing matters: an indicator can summarise what the market has been doing, but it is always built from history. Keep that in mind as you read the rest of this guide, because it's the reason no indicator is a crystal ball.
A moving average (MA) smooths price by averaging the last N closes, so short-term noise gives way to the underlying trend. There are two common types:
Two lengths dominate: the 50-day (intermediate trend) and the 200-day (long-term trend). When the shorter 50-day crosses above the 200-day, that's a golden cross — often read as a bullish regime change. When the 50-day crosses below the 200-day, it's a death cross, a bearish signal. These crosses are slow and lag turns badly, but they capture the big-picture direction well.
The most practical use isn't the cross at all — it's the 200-day as a simple on/off switch. Price above a rising 200-day = uptrend; only look for longs. Price below a falling 200-day = downtrend; be defensive or look for shorts. This single filter keeps many traders out of the worst drawdowns, because it stops you fighting the primary trend.
| Signal | What it means |
|---|---|
| Price > 200-day (rising) | Uptrend — favour longs |
| Price < 200-day (falling) | Downtrend — favour caution / shorts |
| 50-day crosses above 200-day | Golden cross — bullish regime |
| 50-day crosses below 200-day | Death cross — bearish regime |
The Relative Strength Index (RSI) measures the speed of recent gains against recent losses and plots it on a 0–100 scale (usually over 14 periods). It answers "how stretched is this move?" rather than "which direction?"
Here's the trap that catches every beginner: in a strong trend, RSI can sit above 70 for days or weeks while price keeps climbing. Selling the instant RSI touches 70 will repeatedly kick you out of the best trends. Overbought is not a sell signal on its own — it's a description of stretch, and strong markets stay stretched.
A far better use of RSI is divergence. When price makes a new high but RSI makes a lower high, momentum is weakening even though price hasn't turned yet — a bearish divergence. The mirror (price makes a lower low, RSI makes a higher low) is a bullish divergence. Divergence catches fading momentum earlier and more reliably than the raw 70/30 lines.
The Moving Average Convergence Divergence (MACD) is built from EMAs and has three parts:
When the MACD line crosses above the signal line, upward momentum is building — a bullish crossover. When it crosses below, momentum is rolling over — bearish. A cross above the zero line confirms the faster EMA has overtaken the slower one entirely. The histogram often warns you first: bars shrinking toward zero hint that a crossover is coming before it prints.
Every indicator on this page is calculated from past price. That makes them lagging by design — they confirm what has already begun, they don't predict what's next. A moving average turns only after price has turned; an RSI or MACD crossover reports a shift that already happened. This isn't a flaw to fix, it's the nature of the tool.
So treat indicators as context, not commands. Use the 200-day to know which side of the trend you're on, RSI to gauge stretch and spot divergence, MACD to time momentum shifts — but let them agree with each other and with the actual price structure before acting. Above all, never trade an indicator blindly. The traders who last are the ones who pair every signal with strict risk management: a pre-planned stop, a sensible position size, and a loss they can afford. Indicators tell you the odds; risk management keeps you in the game long enough to play them.

All Learn guides →Trading glossary →How leverage works →There is no single best indicator. Beginners usually start with a moving average because it is simple to read: price above a rising 200-day average signals an uptrend, price below a falling one signals a downtrend. Add RSI to gauge momentum and MACD to spot shifts. Use them together as context, never one in isolation.
Not automatically. RSI above 70 is called overbought, but in a strong trend it can stay overbought for a long time while price keeps climbing. Selling every time RSI hits 70 will get you out of winners early. A more reliable signal is divergence — price making a new high while RSI makes a lower high — which hints momentum is fading.
No. Indicators are calculated from past price and volume, so they describe what already happened and lag current price. They help you read context — trend, momentum and stretch — but they cannot see the future. Combine them with risk management and position sizing; never trade an indicator signal blindly.
