RSI — Relative Strength Index

One of the most used indicators in trading. Learn what it’s actually measuring, which settings to use, and how to find the setups that matter.

What is RSI?

RSI measures the speed and size of recent price moves on a scale of 0 to 100. It was created by J. Welles Wilder and published in 1978. It compares the average of up-closes to the average of down-closes over a set number of periods (default 14).

The result tells you how much momentum is behind the current move. It doesn’t tell you where price will go — it tells you how hard price has been pushed in one direction and whether that move is becoming exhausted.

70+
Overbought zone. Momentum is stretched to the upside. Not a sell signal on its own — in strong trends RSI stays above 70 for a long time. Watch for a curl back below 70.
50
Midline. Above 50 = bullish momentum. Below 50 = bearish momentum. The 50 level is underused — a RSI bounce off 50 in an uptrend is often a continuation entry signal.
30−
Oversold zone. Momentum is stretched to the downside. Again, not an automatic buy — but a RSI recovery from below 30 is a meaningful signal, especially with price structure confirmation.

Ideal RSI Settings

Right-click the RSI indicator → Settings. The defaults are close to ideal but the 50 midline is missing and worth adding.

Inputs Tab

Length: 14 Keep the default
Source: Close Keep the default

Period alternatives: Use RSI 9 for faster signals on lower timeframes (5min/15min). Use RSI 21 for smoother swing signals on 4H/Daily. Stick to 14 as your main.

Style & Levels Tab

70 lineKeep — overbought
50 lineADDNot on by default — add it
30 lineKeep — oversold
Background fillKeep — shades zones
80 / 20Only add for crypto scalping

Pro tip: Add the 50 level, set it to a dashed grey line. Once saved, right-click → Save as Default so every new RSI uses your setup.

Reading RSI Correctly

1

Check the trend on a higher timeframe first

RSI in isolation means very little. If the daily trend is up, oversold RSI on the 1H is a buy opportunity. If you’re going against the trend, the same signal has much lower probability.

2

Wait for RSI to exit the zone, not just enter it

Don’t buy just because RSI drops below 30. Wait for it to come back above 30 — that’s the confirmation that momentum is shifting. Same for overbought: wait for RSI to curl back below 70 before considering shorts.

3

Use the 50 midline for trend confirmation

In a healthy uptrend, RSI should hold above 50. If RSI repeatedly bounces off 50 from above, that confirms bullish momentum. A sustained break below 50 can signal a shift in market structure before price even confirms it.

4

In strong trends, adjust your zones

During a strong bull market, RSI often doesn’t reach 30 — it bounces between 40 and 80. Adjust your thinking: 40 becomes the “oversold” level and 80 the “overbought” for that trend. This is called RSI range shifting.

RSI Divergence

Divergence is where RSI becomes genuinely powerful. It occurs when price and RSI move in opposite directions — signalling that momentum is weakening even before price reverses. It’s one of the highest-probability setups in technical analysis.

✅ Regular Bullish Divergence

Price makes a lower low, but RSI makes a higher low. Selling pressure is weakening. Often marks the end of a downtrend.

Price: Lower Low ↓ RSI: Higher Low ↑ Signal: Potential reversal UP

⚠️ Regular Bearish Divergence

Price makes a higher high, but RSI makes a lower high. Buying pressure is fading. A warning that the uptrend may be losing steam.

Price: Higher High ↑ RSI: Lower High ↓ Signal: Potential reversal DOWN

🔁 Hidden Bullish Divergence

Price makes a higher low (trend continuation), but RSI makes a lower low. The trend is still intact — this is a continuation entry, not a reversal.

Price: Higher Low ↑ RSI: Lower Low ↓ Signal: Uptrend continuation

🔁 Hidden Bearish Divergence

Price makes a lower high (trend continuation), but RSI makes a higher high. The downtrend is still intact — a continuation entry to the short side.

Price: Lower High ↓ RSI: Higher High ↑ Signal: Downtrend continuation

Important: Divergence is not a trade on its own. Use it as a warning flag, then wait for price action confirmation — a rejection candle, structure break, or volume shift — before entering.

RSI on NQ, ES & Crypto

🎯

Stack with Fibonacci

RSI oversold at the same time price hits the 61.8% GP zone = very high confluence entry. This is one of the cleanest setups on NQ and Bitcoin.

⏱️

Use multiple timeframes

Daily RSI oversold + 1H RSI curling up = top-down alignment. The higher timeframe sets the bias, the lower timeframe gives the entry timing.

📈

50 level on NQ intraday

On the 15-minute NQ chart, RSI bouncing off 50 during an uptrend is a reliable long entry trigger. Watch for it after a short pullback before resumption.

Crypto RSI extremes

Bitcoin can push RSI to 85-90 in bull markets and 15-20 in crashes. On crypto, don’t fade the extremes during trending conditions — use 80/20 or wait for structural confirmation.

⚠️

RSI is a lagging signal

RSI uses the last 14 candles to calculate. It reacts to price — it doesn’t predict it. The signal comes slightly after the move starts, so always combine with price structure.

🔄

Divergence is rare — don’t force it

Real divergence setups occur a few times a month on any given chart. If you’re finding divergence on every swing, you’re stretching the definition. Be strict about it.

Trading Psychology

Getting the setup right is only half the equation

The other half is what’s happening in your head when you’re in the trade. Fear, ego, revenge trading, breaking your own stops — that’s where most accounts actually lose money. Not bad setups.
