How to Read Trading Indicators
The Complete Plain-English Guide

Every indicator explained simply — what it is, what it actually tells you, how to use it correctly, and the exact mistakes beginners make. No jargon. Real examples with real numbers.

RSI

Beginner
Relative Strength Index
Use case: Spotting overbought & oversold conditions
Plain English: A speedometer for price. It tells you if the market is moving too fast — and about to slow down.
What Is It? (Simple Explanation)

RSI measures how fast and how much price has moved over the last 14 candles. It gives you a number between 0 and 100. Think of it like a rubber band. If you stretch it too far in one direction, it snaps back. RSI tells you WHEN the rubber band is stretched too far.

How to Read It — 4 Signals to Know

Price has gone up too fast. Think of it as a car that's been driving at 120mph for too long — it needs to slow down. This is a SELL signal in the right conditions.

Price has fallen too fast. The market has panic-sold and gone too far down. This is a BUY signal in the right conditions.

RSI in this zone means the market is just moving normally. No extreme — don't trade reversals here.

Price makes a NEW high but RSI makes a LOWER high = bearish divergence. Price is going up but the engine is losing power. Big reversal signal.

Real Trade Example
ES (S&P 500) — RSI Overbought + Divergence Short
// Tuesday 10:15 AM EST — 15-minute chart
ES rallied: 5,380 → 5,416 (+36 points)
RSI reading: 78.4 ← Overbought (above 70)
ES makes NEW high at 5,419
RSI only reaches 74.1 ← LOWER HIGH = DIVERGENCE
🎯 SHORT signal confirmed at 5,416
Stop: 5,428 (above swing high)
Target: 5,386 (back to 20-period average)
✅ Result: Dropped to 5,387 in 1h 20min
Profit: +29 pts = +$1,450/contract
❌ Common Mistakes Beginners Make
✗Trading RSI alone without price structure — RSI above 70 can STAY above 70 in strong trends
✗Not waiting for divergence — overbought is a warning, divergence is the actual signal
✗Using the wrong timeframe — RSI on 1-minute charts creates too much noise
Recommended Settings

Period: 14 (default). Overbought: 70. Oversold: 30. Best timeframes: 5m, 15m, 1H.

The Verdict

Use RSI for confirmation, not as your only reason to trade. When RSI divergence matches a key price level, the signal becomes high-probability.
